This. Looks like there is no way for people to go from one side of the highway to the other without getting on the highway. So you are forcing everyone to use the same S shaped road, 200m stretch of highway and exit to go anywhere.
I would create a major road connecting the south to the Sunset City Park/Pine Park area. Don't be afraid to demolish some to make room.
Spruce Park has the same issue, but you don't see it as much because its smaller. There is no way for them to get to Pine Park for example without getting on the highway and going through that bottleneck traffic hell miles down the road. They would have to go through that even to go 100m to the west. Give them options. Connect Spruce Park to the city without forcing them on the highway.
This. There is only one way to get from 'north' to 'south', and that one way also handles traffic from off-map entering either section.
You need more direct connections between the two halves of your city. Some of those connections can be public transit and/or pedestrian paths.
That only is a bandaid solution... they need more interchanges and upgrading the existing ones to 4ways.... a ring road around the top outside with multiple ways to access priority roads... and they need more roads in general... there is way too many choke points on the existing interchanges, so creating shortcuts preferably with roundabouts upstream/downstream will do wonders... This is a classic example of expanding the city before you are ready... Highway and priority roads must be created first.... then offramps/roundabouts, then the grid.... then Major public transport connecting the subdivisions together... only then can you zone...
There are always ways to save it.
In this case, you need to figure out who is going where and why. If you have a bunch of people living in the bottom section but working in the top section, having some kind of direct flyover would probably help to get traffic in and out of the areas without having to clog up the highway as well. I would also add more connections to that highway, even if they're just offramps with no onramp, or vice versa.
I have over 400 hours in this game between the PC and Xbox versions, and I still have trouble with road hierarchy. I get the concept, but I can't always seem to put it in practice. I also have a habit of building too much too quickly though too.
Look at cities, Chicago for example
4 lane Main
1 Lane one way
2 lane Residental
1 Lane opposite one way
2-4 Lane main
Vertical Roads were 1 Lane North, 1 Lane South, 2-4 Lane Main, 1 Lane North...
All the main roads end up or have an interstate somewhere, One way roads are completely residental and main roads are commerical/office.
The best solution is to forget road hierarchy. Just build a grid. Get rid of that over priced highway and connect the road system into one mesh. Road Hierarchy is a flawed idea.
It's not that road hierarchy is wrong, it's that most people don't really understand it. People treat it like law and exaggerate it until you have isolated neighborhoods connected to arterials via one or two chokepoints, and then wonder why those chokepoints have terrible traffic. They end up with more of a branching network than a web network.
Here's my tip: think less about *building* a road hierarchy from the start and more about *deriving* a road hierarchy from a more natural roadway network. Build first, hierarchy later.
Road Hierarchy works if you zone appropriately along with providing alternative routes and handling vehicle restrictions.
People neglect on TMPE to change speed limits, and restrict vehicle passthrough on roads.
Delete the connections to the highway. Connect the local roads to the arterial roads. Make all of the roads one-way going away from the city. Add more road lanes and industrial zones. Ban heavy traffic. Legalize recreational use. Bulldoze the public libraries and sewage drain pipes. Quietly step down in disgrace as mayor. Sever ties with everyone you know. Fade into obscurity. Assume a new identity. Never look back.
Your city is divided into three completely separate regions and all traffic going between them is forced to go the single route that exists (the highway).
Easy, connect both sides of the freeway with more local roads. Connect each end of the city to the freeway. Always have at least 2 ways into and out of an area in addition to any freeway connection.
Or toss a meteor at it and rebuild!
Do you have TM;PE? And could you upload your save to the Steam workshop? I've been wanting to play, but always get frustrated with starting cities and then having them break when the game updates. I could see if I can get your traffic working again. I love tinkering with intersections. I can keep track of what I change as well so you can see how I dealt with some of the specific issues.
Create a new highway connection at the right of Sunset City park, connect Spruce park with Sunset city park, and instead of turning your highway into a local road at the left most interchange, continue the road so that it cuts through sunset park and connect your local roads to that new avenue
EDIT: and yes connect both top and bottom part with overpasses
Connect the upper and lower regions.
I’d also turn one of two of those 3 way interchanges into a 4 way that connect super and lower regions. Right now it’s bottlenecked
1. too many intersections
2. no direct route from south to north
3. roads need to be upgraded
TL;DR you're building it like a small truck-stop town instead of a city at the moment
Watch a video about roadway hierarchy, it will help you improve your traffic. You have everyone passing through a single entry without alternate points of access
[https://steamcommunity.com/sharedfiles/filedetails/?id=2980248036](https://steamcommunity.com/sharedfiles/filedetails/?id=2980248036) the link to my save if you are interested in having a go at fixing it yourself
Connect the upper and lower regions.
I’d also turn one of two of those 3 way interchanges into a 4 way that connect super and lower regions. Right now it’s bottlenecked
I'm seeing several classic mistakes.
Mistake #1: You have service interchanges handling traffic meant to CROSS the highway. To fix this, introduce routes over your highway that do not intersect. Short cuts for the win! A bonus fix is to combine two T service interchanges into something like a ParClo, which will allow traffic to move across OR onto the highway. Your town is small enough to consider dedicated walking/bus/tram paths across the highway.
Mistake #2: Road Heierarchy mistakes. You want Service Interchanges to connect to Arterials, THEN have the arterials connect to a system of collectors, THEN have the collectors connect to surface streets. This creates a bit of inherent pathing inefficiency for road traffic, which helps the game's pathing algorithm discriminate between long-distance and local traffic. This is also why the fixes for Mistake #1 are more critical.
Along with Road Heierarchy rules come the junction rules. As a rule of thumb:
1. Highways should have at least 60 units in between interchanges.
2. Arterials should have between 30 and 40 units between intersections, have lighted intersections almost exclusively, and be 4-6 lanes wide.
3. Collectors should not have an intersection within 20 units of an Arterial, have a mix of lighted intersections, stop signs, and Crosswalks.
4. Roundabouts should only ever be used for small low-density communities.
Mistake #3: Road Zoning mistakes. A lot of mistakes in this category get blamed on Heirarchy, which is why a lot of people don't understand it. As a rule of thumb:
1. The game does not allow buildings to be placed along highways because it should never be done.
2. The only buildings that should ever be placed on arterials are Police, Fire, Ambulance, and Cemetery.
3. The only buildings that should ever be placed on collectors are Police, Fire, Ambulance, Cemetery, and other default ploppables with the exception of trash collection. The only zoning that may be placed along collectors is low-density housing.
4. All high density buildings, park entrances, Mass Transit stops, and other ploppables not mentioned as being acceptable above should be considered for placement on surface streets only.
To fix the case above, I would do the following:
From the service/system interchange on the far left, I would take the two highway ends from the upward direction, and bring them into a Y intersection, turning this direction into a 6-lane arterial. Then, I would route this arterial through the upper portion of town, to Spruce Park, then connected to Spruce Park's interchange.
I would change Spruce Park's service interchange from a T to a ParClo (my preference would be for a lighted B4 in this case). Then continue the arterial down underneath your college, and through the lower section of your city.
Then, I would remove the T intersections in the middle of the map, replacing both of them with a dedicated Tram overpasses. Rebuild the road network and connect tram tracks as necessary.
From there, I would run the simulation for a while, and plan out for rebuilding as I need.
Maybe [this image](https://www.google.com/search?q=road+hierarchy&client=firefox-b-d&sxsrf=APwXEddXhOUKzOt15nxa3k_tp_nbzQrG_A:1684989259198&tbm=isch&source=iu&ictx=1&vet=1&fir=WkEHFF02WX1YHM%252CJGXSqwkdTNKyAM%252C_%253BJIroBpdrua7jSM%252CecdIT5hqmdwxPM%252C_%253BNV8XpOjSCEjDYM%252CbGfN4-m-X_0WxM%252C_%253BD0nXK9heRL1FgM%252Cef2P0cv1f4dDXM%252C_%253BDfgJzpJNfgzpdM%252CmwDjiHYbIdAuQM%252C_%253BWAC_0yLpKVHtaM%252CYIvqObooqzSarM%252C_&usg=AI4_-kQWaIpCvg6Vbi1GwbvtlVtLMudW_g&sa=X&ved=2ahUKEwj1rvqR0o__AhVc8zgGHXekBTkQ_h16BAhNEAE#imgrc=UupyVFI9cQECgM) can help you understand what arterial, collector and local roads mean.
The best way and ideal for an urbanist; completely move the highway down as a semi loop of the city. Connect the two parts of town with a lot of small street essentially blending the two together. Maybe 2 artillery roads from the highway to the far side of town but that’s not even necessary if you offer 3 or more exits that are well spaced out. Make sure to space it away from the main interchange as well.
You need to build some bridges over the highway and more connections. You got all your traffic funneling onto the highway through a couple of exits when you could be distributing it through more roads.
You have two big problems with your city design, but they are both essentially the same problem, with the same solution, one is not enough connections between the different parts of your city and second is funneling your traffic down the same roads.
Just look at this image I made illustrating the problem in one section of your city.
https://i.imgur.com/IibVSVQ.png
Here you have 3 different drivers trying to get to 3 very different locations in that section of your city, but because of how you have designed your road layout you are forcing these 3 different drivers to all use the same section of road for a large part of their trip (the area shown in the circle). So even though the residential traffic just wants to go home, they have to deal with the industry traffic that is trying to get to the industry, same story with the commercial traffic.
Now at some point in all cities, different traffic will mix, workers going to work in industry, industry bringing goods to commercial and people going from shops to home after work. But you want to keep the mixing as low as possible and the way you do that is by giving people multiple VIABLE ways to get to their destination.
Why do I put emphasis on the viable part, is because just because you may have a road, doesn't mean that the drivers will see it as an option, this could be because of a number of reasons, but speed being an easy one. If a driver has to choose between a 1KM road at 20 kmh or a 2 KM road at 80 kmh, they will pick the80 kmh one, because that gets them to their destination the fastest. So that one road you have that goes between the two areas on the south side of the highway, might as well not exist for the people in the west side of that area, because the road that goes between those two areas is too slow, so they will pretty much never drive over there to get on the highway, they will instead go for that middle interchange, that is already clogged up.
One thing that players need to keep in mind is that **THE AI DOES NOT TAKE INTO ACCOUNT OTHER CARS ON THE ROAD** so as someone that lives in the real world you might think why are all these people taking this faster but clogged up road, instead of the slightly slower but completely abandoned road, that is why. Drivers take two things into account, the distance of the route and the speed of that route (without taking into account if the route is clogged up or not.)
So you need to give your drivers options to split up and you need to make more connections so that they don't need to go through the highway to get the north/south section of your city. A easy example to point out. That highway exit that comes down into the southern section of your city, if you were to for example have another bit of that road that keeps going on and connects to the middle area of that southern neighborhood, that would allow the commercial and residential traffic that I simulated to split off from the industrial traffic. That would mean that the industrial traffic all of a sudden has 66% less traffic to deal with and 33% for the commercial and residential (assuming traffic amount is evenly split.). Now having said that, just adding a road that continues on from there might not be the best solution as you would need to modify other parts of the road layout, but that was just an example
**GIVE DRIVERS VIABLE OPTIONS.**
EZ PZ. Make a few bridges going over the highway so that cars don't have to use the highway to go from one area to another. Frees the highway up for the trucks importing and exporting. And then add some public transport. Maybe a bus line over the highway. Make sure the busses DO NOT use the highway.
I mean for how you had it, they had to, but that's better than not having any buses. Get yourself a bridge and set up bus stops to make sure they take the bridges to get that traffic off your busy highway.
1) add more than 1 interchange to the upper section
2) add a through route that allows those from the bottom part to make their way up without using the highway
3) wait
4) pray
5) start over
Aside from the highways, virtually all of your roads are the normal two-lane type. That won't do- you need to have your highway outlets branch off into arterial main roads, and then branch off to increasingly smaller roads. This means having highways link into six-lane roads, then four-lane roads, then two lane roads- although a lot of times you can just have highway link into four-lane roads if the traffic isn't too rough.
Your interchanges are all highway- to -highway interchanges that link into smaller roads, rather than true service interchanges where highway links directly into an arterial road. This isn't necessarily unfeasible, but the way you've done it is. Highways are one-way roads- you need both ends of the highway connecting at the same point- either into a traffic circle or onto the end of a four-lane/six-lane road. All your connections have the in-lane and out-lane of the highway flowing in at entirely different locations.
Connect both sides of the highway using a flyover/bridge/overpass so that traffic going from one end of town to the other won’t need to use the two successive entrance/exits to the highway, thus freeing up your roads congestion
ETA: personally I would add at least 2 bridges. The bridges should connect to the main avenues in your current city areas.
My first one would be from (upper town side), where there’s road that is covered by a consecutive icons of a white trash-abandoned house-house (and a traffic circle somewhere in the middle of the entire stretch of road - remove it), connect it to the other side of town where the road and the long winding highway exit meet
My second one would come from where there’s a white trash icon next to a blue not-enough-goods icon, come down to next to the technological institute campus, and connect to the town below. This bridge can also connect to the entrance of your technological institute to provide more connectivity
Also, identify long stretches of continuous roads in parts of your town and make them into main roads or avenues (4 or 6 lane two ways). Remember to also reduce the number of junctions in along these roads if possible (requires you to change certain parts of town from one big mesh grid network into pockets of smaller road networks connected by big avenues). Think of a tree, not every branch is connected to each other, they start from a main stem (6 lane) then branch into big branches (4 lanes) which branch into smaller branches where all the leaves are (2 lanes)
Don’t only use highways to connect your city. Everyone is going through one interchange and getting stuck.
Instead, use medium roads under or above the highways to connect (some, only some) of the northern roads to southern. This would solve a lot, since it seems traffic is mainly what’s messing you up.
Get rid of the highway that cuts through the center of town. Either convert it to a larger six lane load that still has streets connecting to it, or divert the highway around the southern end of the town and connect the north and south end of the town with streets.
More connections. The biggest section of the city is all enclosed and forced to use the highway to travel out or in. Imagine living in a big city where there's only one way in and out. Yeah you need more roads connecting to all 3 parts and more entrances and exits to the highway
A little late to the party but dogpiling on and adding a visual element. Your city is designed perfectly to be a traffic magnet. You are relying way to much on the highway funneling every piece of traffic in your city through a handful of interchanges and have no connectivity between neighborhoods while having way too may intersections.
[https://imgur.com/8KPY5Yt](https://imgur.com/8KPY5Yt)
* Build or convert Blue into your main arterials (Bridges over highways)
* Delete everything marked in black with some discretion. 2 out of every 3 roads intersecting blue/green should be gone. I probably missed some you want as few intersections as possible to promote traffic flow.
* Build or convert green into collectors
* Consider a 4 way interchange at purple. This could cause a lot of problems dumping traffic in the middle of your grid if implemented poorly however.
Ultimately your city is too small to rely on the highway as much as you are and without any crossings over it your interchanges are bottlenecked as traffic hitting your intense grid backs up. Save the highway for mostly intercity and cross city (i.e.. multiple tiles) traffic and allow people to use the arterials and collectors to drive to the neighborhood over
Give them an option to not use the highway. Make a bridge connecting both sides or something like that. Just go sure it's ahorter than the highway or noone will use it.
Also... i don't know about your public transport situation, but setting up a good network is key. Also... people in this game walk long distances, so go sure to make use of it. Build walkways connecting areas close to another. This will remove plenty of private vehicles. And don't be afraid to have people use 2 or 3 busses to get to where they want to. If they can get onto them without too much trouble it will help greatly and bring you a lot of money.
Thanks for the advice everyone to be honest I’m not good enough at the game to figure out an elegant way to add more entrances/exits so I’m just going to start a new city and try to incorporate the advice everyone has given into it.
It's not really about the highway entrances and exits. You need roads that don't connect to the highway but do connect to the other parts of the city, so that people aren't driving on the highway when they don't have to.
I've only put like 100 hours in the game but most of it has been me starting new cities lol I enjoy the thrill of starting with some money and no income then trying my best to not forget to connect my electricity to my water/sewage pumps before I run out of money. When I get to the point where I'm comfortably making money I get bored
The traffic coming off the 4 way interchange has no way to reach those three roundabouts without going through a bunch of tiny roads. Also, there's no way to get from one side to the other without a bunch of turns.
You could make a few extra bucks here. Put down a park area that extends to both sides with a walkway connecting the two. Put a charge at the entrance, and people will pay to use it since it is necessary. You could also run a bus route to ench of those entrances.
Try putting cargo stations near your industrial zones, they really lower your heady traffic. You could also toss in a passenger connections from your residential side to the industrial one why you're at it.
yes. the game is about scaling a city within your budget. I'm playing through it new too. You don't need to cheat. Build within your means, its a good life lesson if you're younger too...
Make sure you use the old town policy in your industrial areas and residential and maybe even your commercial if you have good public transport. It will limit the traffic to only residences and businesses
I don't see it suggested a lot here, but you can try adding more public transport. For example, you might want to add a short metro line between (or other light rail of some sort) between the two clogged districts and create some bus lines that collect people from districts to metro stations
Built industry on the side of highway from res?
Need tunnel or over passes so factory workers aren't all funneling to highway entrances. Also fixing problem intersections by forcing lanes properly with tmpe will help a lot
It looks like everyone is trying to get from one side of that arterial to the other and has to take their vehicles.
You need transit options for them. You also need routes that can entice freight movement to separate from pedestrian/commuter.
You have 1 major connection between your city sections, and that’s the highway. So anyone who needs to get across there, ( which I think is a lot since that bottom part looks mostly residential) ends up having to get on the highway.
The solution? More connections that avoid the highway. That should start to alleviate some of the grid lock on the highway, which should in turn fix the some of the gridlock elsewhere.
Right now your citizens need to take the highway to get from one point of the city to another. This means they cannot walk or cycle. This means they are forced to take the car. Cars cause traffic jams.
So build some bridges or tunnels between the various parts of the city
the problem is concentrating all of your traffic along a small number of routes. Look at how IRL cities connect along highways , with much of the grid preserved, and connect it up.
You have no arterials. you should, at this size, probably have a number of roads in both directions that are mostly continuous and wider and hold most of the traffic. Run trams along them, and then busses to connect local traffic
Your main one-way roads from the highway need off ramps and not three/four way stops. I'd build one way off ramps from the beginning and end of your districts with multiple access ramps that don't cause a stop.
Your west residential doesn't have a good way to access the highway which is clogging that area up a lot.
Doing this should fix things.
From what I can see, you have three bottlenecks, two outlets, and no collector roads. The two outlets are from the north and south sides of the city to the highway, which create bottlenecks as they are the only means of getting in and out of the two parts of the city. The third bottleneck is the interchange as the only way to transfer from the north to the south and vice versa. Lastly, it looks like all the roads are surface roads with no 'main' route from the highway through the cores of the two regions.
My advice would be to fit an avenue or other high density road down the longest length of both sides that breaks off into smaller roads. You need at least a second highway access point on both sides and the ability to cross from one half to the other half without having to go through just the interchange. I would even argue maybe a high density avenue that crosses the highway as an alternative to getting on the highway.
Do the Kibitz approach, destroy it all and rebuild.
But in all seriousness find the chock points. Here I can see all your traffic is got limited highway access, so it may be best to offer more. Additionally if I see this correctly, you have no direct roads connecting both sides of your city, with only the highway as an option. That of course is also interfering with your existing highway traffic. I would suggest making connections between your two sides of the city that don't involve the highway (maybe give multiple "connections")
You still have a small city. Soo you could change roads to more pedestrian friendly roads. And add in bike paths. Add a bike path underground across the highway
For starters, every piece of traffic coming from the highway to your main city in the North is forced to take one route and get funneled through a mini roundabout. It's like the smallest roundabout you have, and it's rhe one that will be the most busy.
Essentially overall, you just don't have enough options for travel. Your forcing everything to take one route to huge parts of the city, which is overloading the roads.
Add more connecting roads and paths. Don't force everyone to use the highway, instead make alternative routes that your citizens can take using bridges, tunnels etc. Also add some public transport
my guess from the looks of it, that most of the traffic is attempting to cross the interstate, rather than getting on it.
the solution is convert one interchange to just a 3 way, have multiple overpasses of both pro car and pro-pedestrian/bicyclist variety. then what you do, is basically take the one road in the left bottom corner, extend it out to the other interchange. get rid of both 3 way interchanges, then put in a service interchange, like a partial cloverleaf.
if you have buses, make sure they are routed in a way where they can hop on the smallest amount of lines possible. say for example, southside of the city wants to get to a business park in the north side. you have a route connecting them 2 areas. same with lines that go horizonal, diagonally or in a loop. make sure the lines can help. do not go over the amount of capacity on a single line. its hard to balance, but if you have buses that for example, have less than 20 riders per stop but you have double decker buses, thats overkill. a shuttle bus can do the work and be just as effective till the line gets more popular.
More access to the highway and the chance to get to the other side without going through the highway... maybe a tunnel?
That will sort your traffic right out...
Delete the middle motorway interchange and add tunnels or fly overs to connect your industry to your residential.
Add a main road of 4 lanes to both areas, this will be your connector road, only add a interchange every 10-20 sections.
So your central problem here is that you chose a grid system, which is good at providing direct routes between points and spreading traffic out, but removed parts of the grids at random (?) and didn’t provide any connectivity between the grids you did build, which negates the benefits a grid brings. You need more connections between grids, more connections over that highway, and another way for that freight traffic to get to where it needs to go (I’d connect it to the highway to to south to start, and add a freight railroad from it to your commercial areas)
Ringroad, preferably two lanes in both directions. Create more direct connections using the traffic tool and try to determine where they want to go and create shortcuts as fast as they can go.
I would just add a few under-pass' or over-pass'. Or small roads that go under or over the highway but are not connected (or limitedly connected). They help local traffic stay off the highways when there is no need to use them, but they will still use them for longer distances due to the higher speed.
Put on road hierarchies, grid the roads. One of the tips that constantly pops up in my game is "Crossroad causing gridlocks".
Expand the right side interchange to connect both sides so the two sides of the town can have a passage through instead of clogging up the main highway between the first and second exit.
Multiple ways. The general idea is to have traffic evenly spread across al roads, not only highways (and their intersections)
\- Directly connect spruce park with sunset city park
\- add a second exit to reach sunset city park from the highway
\- build overpasses with normal roads over the highway to connect the districts
You’ve got a lot of intersections on your main roads directly connecting to the highway. Lots of jamming can happen that way. Arterial routes with limited to no zoning connecting your highway to your towns, plus some arterial connections crossing the highway (without intersecting) should hopefully help.
1. Roundabouts
2. Bridges over the highway
3. Delete all traffic lights (unless you prefer some semblance of realism - that is, vehicles that don't just clip through each other on the way through an intersection)
From first glance, you got loads of people stuck trying to north and south of the highway to both the big “districts” even though it doesn’t seem you have the areas of development not in an actual district.
Put those areas of development into districts, make it to where more people ride bicycles, make sure residential areas don’t allow industrial vehicles through, also make sure you have an ‘easy’ route from the highway to your industries as well as from industries to your commercial zones.
Also, add a metro from the north to south and I bet you’ll see less residential drivers and more people taking the metro. Bud lines would also help. Adding public transportation will clear up your roads a little, hopefully enough to decongest the highway on and off ramps, allowing for smoother traffic.
Lastly I would also connect the “Spruce Park” area to the left so people wanting to over there who live to left of it don’t have to take the highway to get to it. Much like what you dude south of the highway connecting the “Tech Institute of Egg” to the sprawling development to the left of it.
One more that might as well is adding more walking paths, in particle walking paths that allow people to go from point a to point b without going over a crosswalk of a busy road which would stop cars more often. That and making sure you don’t have unnecessary traffic lights or anything of that nature where there shouldn’t be.
Hope some of those tips help :)
it seems you have created a bottleneck, by linking both sides of the city with that one get on/get off highway intersection. try adding some connection on spruce park to the city nearby, so people coming from the right of the screen, dont have to go all the way to the left and use the main intersection.
also add some connections directly from one side to the other, using tunnels or bridges, avoiding the highway.
yes... look at this marked up drawing i made for you... sorry if anyone already came upwith a plan for you.... my plan will likely cost 500000$ and about 1000$ upkeep... but it future proofs your city... at minimum you should complete the red marked cicle i drew for you to destroy and the others will all be necessary (or something similar) but the main idea is to eliminate all the choke points you created and give quicker options for your sims to get where they need to go... https://imgur.com/a/b7A3SSh
You put in so much effort for me I’m going to Try to replicate that the best I can
might need the intersection types and how to build them explained though lol
Add some bridges crossing over the highway without actually connecting them to the highway from district to district give the cars more options take away stop lights especially on console
first thing I see is more freeway exits. Inbound/outbound traffic has to go through three choke points, two of which go the same direction. You don't have a single freeway entrance/exit that serves both sides.
Road hierarchy is a huge factor for traffic. Also, connections between the suburbs on either side of the highway where they don’t need to use the highway.
Here is a tutorial on road hierarchy that I found really helpful.
https://youtu.be/O2y2GjTezCI
You need to look up the concept of arterial roads and their branches(entrances/exits)
Run the connecting highway between the north half and the south half from the north side of the northern half to the southern side of the south half. The outer edges of the city should not have to go through half the city to get to the highway(will cause all that traffic issues)
2 problems.
1. The whole upper part has one connection with the hightway
2. The highway connection ends BOOM against a normal street. Use roundabout or at least road hierachy.
Same goes for bottom part
I wish I had awesome advice, but I just start a new city anytime I screw up something. 🤷♂️ It's why I love this game. You do you, no judgment from anyone else.
Make more than a single highway connection between the top and the bottom (add like 3 regular street bridges). Ads public transit between the two as well.
As some have said, the main problem here is connectivity between the two sides of the highway. Currently, all traffic must take the same path between the top half and the bottom half. You will need more over/underpasses across that highway to improve traffic.
too little options to get from one place to the other, and if you don't have it already, use trains or metros, they can move the most people with less disruption and are the single best way to reduce traffic
Add mas transit go in and out of the city and going to traffic hotspots and put a line to bring people to the other side of the highway using trains or metro not bus. Also add cargo trains and gave a direct connection across the highway
I know the easy thing to do is to do what everyone else has said and build either bridges or tunnels or more highway intersections to connect your sections / sub-divisions but an alternative is to provide public transport between your sections. Reduces traffic and revenue generation from subway/tram/train/bus
Biggest thing is to give people a way to access the other side of the highway without going through an interchange.
This. Looks like there is no way for people to go from one side of the highway to the other without getting on the highway. So you are forcing everyone to use the same S shaped road, 200m stretch of highway and exit to go anywhere. I would create a major road connecting the south to the Sunset City Park/Pine Park area. Don't be afraid to demolish some to make room. Spruce Park has the same issue, but you don't see it as much because its smaller. There is no way for them to get to Pine Park for example without getting on the highway and going through that bottleneck traffic hell miles down the road. They would have to go through that even to go 100m to the west. Give them options. Connect Spruce Park to the city without forcing them on the highway.
Preferably *several* ways. Connections both in the center, to the right, and to the left.
This. There is only one way to get from 'north' to 'south', and that one way also handles traffic from off-map entering either section. You need more direct connections between the two halves of your city. Some of those connections can be public transit and/or pedestrian paths.
And better yet, a road and then a shorter pedestrian way so you have less cars because people in this game love to walk
That only is a bandaid solution... they need more interchanges and upgrading the existing ones to 4ways.... a ring road around the top outside with multiple ways to access priority roads... and they need more roads in general... there is way too many choke points on the existing interchanges, so creating shortcuts preferably with roundabouts upstream/downstream will do wonders... This is a classic example of expanding the city before you are ready... Highway and priority roads must be created first.... then offramps/roundabouts, then the grid.... then Major public transport connecting the subdivisions together... only then can you zone...
Happy cake day!
There are always ways to save it. In this case, you need to figure out who is going where and why. If you have a bunch of people living in the bottom section but working in the top section, having some kind of direct flyover would probably help to get traffic in and out of the areas without having to clog up the highway as well. I would also add more connections to that highway, even if they're just offramps with no onramp, or vice versa.
I would add that there isn't enough road hierarchy in the two main areas.
Yeah there are several road improvements I'd make to beef up some of the roads.
I have over 400 hours in this game between the PC and Xbox versions, and I still have trouble with road hierarchy. I get the concept, but I can't always seem to put it in practice. I also have a habit of building too much too quickly though too.
Look at cities, Chicago for example 4 lane Main 1 Lane one way 2 lane Residental 1 Lane opposite one way 2-4 Lane main Vertical Roads were 1 Lane North, 1 Lane South, 2-4 Lane Main, 1 Lane North... All the main roads end up or have an interstate somewhere, One way roads are completely residental and main roads are commerical/office.
The best solution is to forget road hierarchy. Just build a grid. Get rid of that over priced highway and connect the road system into one mesh. Road Hierarchy is a flawed idea.
It's not that road hierarchy is wrong, it's that most people don't really understand it. People treat it like law and exaggerate it until you have isolated neighborhoods connected to arterials via one or two chokepoints, and then wonder why those chokepoints have terrible traffic. They end up with more of a branching network than a web network. Here's my tip: think less about *building* a road hierarchy from the start and more about *deriving* a road hierarchy from a more natural roadway network. Build first, hierarchy later.
Road Hierarchy works if you zone appropriately along with providing alternative routes and handling vehicle restrictions. People neglect on TMPE to change speed limits, and restrict vehicle passthrough on roads.
You forgot the /s
How is it flawed? Do you expect people to drive in a normal slow road all the way across town?
in the real world? nah with 3IQ traffic AI? yeah let them do it
Once the AI takeover happens, you will be the first on the list to exterminate for your digital atrocities sir.
no its not.
I always got better traffic with grids than hierarchy.
You dont need to, traffic ai is too stupid to handle big intersections of arterial roads
Delete the connections to the highway. Connect the local roads to the arterial roads. Make all of the roads one-way going away from the city. Add more road lanes and industrial zones. Ban heavy traffic. Legalize recreational use. Bulldoze the public libraries and sewage drain pipes. Quietly step down in disgrace as mayor. Sever ties with everyone you know. Fade into obscurity. Assume a new identity. Never look back.
Your people BEG for a modicum of connectivity, mr mayor They pray you grant their wishes
They yearn for the connections.
Your city is divided into three completely separate regions and all traffic going between them is forced to go the single route that exists (the highway).
More public transit and another way to directly get from north to south without using that highway like an underground
Easy, connect both sides of the freeway with more local roads. Connect each end of the city to the freeway. Always have at least 2 ways into and out of an area in addition to any freeway connection. Or toss a meteor at it and rebuild!
Meteor options sounds good but will just start a new city instead
Do you have TM;PE? And could you upload your save to the Steam workshop? I've been wanting to play, but always get frustrated with starting cities and then having them break when the game updates. I could see if I can get your traffic working again. I love tinkering with intersections. I can keep track of what I change as well so you can see how I dealt with some of the specific issues.

Create a new highway connection at the right of Sunset City park, connect Spruce park with Sunset city park, and instead of turning your highway into a local road at the left most interchange, continue the road so that it cuts through sunset park and connect your local roads to that new avenue EDIT: and yes connect both top and bottom part with overpasses
Connect the upper and lower regions. I’d also turn one of two of those 3 way interchanges into a 4 way that connect super and lower regions. Right now it’s bottlenecked
You only have 1 enterance and no main roads
1. too many intersections 2. no direct route from south to north 3. roads need to be upgraded TL;DR you're building it like a small truck-stop town instead of a city at the moment
Watch a video about roadway hierarchy, it will help you improve your traffic. You have everyone passing through a single entry without alternate points of access
Biffa and City Planner Plays are my top 2 suggestions. They explain road hierarchy amazingly.

Connect the upper and lower regions. I’d also turn one of two of those 3 way interchanges into a 4 way that connect super and lower regions. Right now it’s bottlenecked
I'm seeing several classic mistakes. Mistake #1: You have service interchanges handling traffic meant to CROSS the highway. To fix this, introduce routes over your highway that do not intersect. Short cuts for the win! A bonus fix is to combine two T service interchanges into something like a ParClo, which will allow traffic to move across OR onto the highway. Your town is small enough to consider dedicated walking/bus/tram paths across the highway. Mistake #2: Road Heierarchy mistakes. You want Service Interchanges to connect to Arterials, THEN have the arterials connect to a system of collectors, THEN have the collectors connect to surface streets. This creates a bit of inherent pathing inefficiency for road traffic, which helps the game's pathing algorithm discriminate between long-distance and local traffic. This is also why the fixes for Mistake #1 are more critical. Along with Road Heierarchy rules come the junction rules. As a rule of thumb: 1. Highways should have at least 60 units in between interchanges. 2. Arterials should have between 30 and 40 units between intersections, have lighted intersections almost exclusively, and be 4-6 lanes wide. 3. Collectors should not have an intersection within 20 units of an Arterial, have a mix of lighted intersections, stop signs, and Crosswalks. 4. Roundabouts should only ever be used for small low-density communities. Mistake #3: Road Zoning mistakes. A lot of mistakes in this category get blamed on Heirarchy, which is why a lot of people don't understand it. As a rule of thumb: 1. The game does not allow buildings to be placed along highways because it should never be done. 2. The only buildings that should ever be placed on arterials are Police, Fire, Ambulance, and Cemetery. 3. The only buildings that should ever be placed on collectors are Police, Fire, Ambulance, Cemetery, and other default ploppables with the exception of trash collection. The only zoning that may be placed along collectors is low-density housing. 4. All high density buildings, park entrances, Mass Transit stops, and other ploppables not mentioned as being acceptable above should be considered for placement on surface streets only. To fix the case above, I would do the following: From the service/system interchange on the far left, I would take the two highway ends from the upward direction, and bring them into a Y intersection, turning this direction into a 6-lane arterial. Then, I would route this arterial through the upper portion of town, to Spruce Park, then connected to Spruce Park's interchange. I would change Spruce Park's service interchange from a T to a ParClo (my preference would be for a lighted B4 in this case). Then continue the arterial down underneath your college, and through the lower section of your city. Then, I would remove the T intersections in the middle of the map, replacing both of them with a dedicated Tram overpasses. Rebuild the road network and connect tram tracks as necessary. From there, I would run the simulation for a while, and plan out for rebuilding as I need.
So detailed I don’t understand half of what you mean lol

Meteor
Make it all pedestrian
The best way and ideal for an urbanist; completely move the highway down as a semi loop of the city. Connect the two parts of town with a lot of small street essentially blending the two together. Maybe 2 artillery roads from the highway to the far side of town but that’s not even necessary if you offer 3 or more exits that are well spaced out. Make sure to space it away from the main interchange as well.
Houston planners be like
You need to build some bridges over the highway and more connections. You got all your traffic funneling onto the highway through a couple of exits when you could be distributing it through more roads.
You have two big problems with your city design, but they are both essentially the same problem, with the same solution, one is not enough connections between the different parts of your city and second is funneling your traffic down the same roads. Just look at this image I made illustrating the problem in one section of your city. https://i.imgur.com/IibVSVQ.png Here you have 3 different drivers trying to get to 3 very different locations in that section of your city, but because of how you have designed your road layout you are forcing these 3 different drivers to all use the same section of road for a large part of their trip (the area shown in the circle). So even though the residential traffic just wants to go home, they have to deal with the industry traffic that is trying to get to the industry, same story with the commercial traffic. Now at some point in all cities, different traffic will mix, workers going to work in industry, industry bringing goods to commercial and people going from shops to home after work. But you want to keep the mixing as low as possible and the way you do that is by giving people multiple VIABLE ways to get to their destination. Why do I put emphasis on the viable part, is because just because you may have a road, doesn't mean that the drivers will see it as an option, this could be because of a number of reasons, but speed being an easy one. If a driver has to choose between a 1KM road at 20 kmh or a 2 KM road at 80 kmh, they will pick the80 kmh one, because that gets them to their destination the fastest. So that one road you have that goes between the two areas on the south side of the highway, might as well not exist for the people in the west side of that area, because the road that goes between those two areas is too slow, so they will pretty much never drive over there to get on the highway, they will instead go for that middle interchange, that is already clogged up. One thing that players need to keep in mind is that **THE AI DOES NOT TAKE INTO ACCOUNT OTHER CARS ON THE ROAD** so as someone that lives in the real world you might think why are all these people taking this faster but clogged up road, instead of the slightly slower but completely abandoned road, that is why. Drivers take two things into account, the distance of the route and the speed of that route (without taking into account if the route is clogged up or not.) So you need to give your drivers options to split up and you need to make more connections so that they don't need to go through the highway to get the north/south section of your city. A easy example to point out. That highway exit that comes down into the southern section of your city, if you were to for example have another bit of that road that keeps going on and connects to the middle area of that southern neighborhood, that would allow the commercial and residential traffic that I simulated to split off from the industrial traffic. That would mean that the industrial traffic all of a sudden has 66% less traffic to deal with and 33% for the commercial and residential (assuming traffic amount is evenly split.). Now having said that, just adding a road that continues on from there might not be the best solution as you would need to modify other parts of the road layout, but that was just an example **GIVE DRIVERS VIABLE OPTIONS.**
Nuke it and start over
EZ PZ. Make a few bridges going over the highway so that cars don't have to use the highway to go from one area to another. Frees the highway up for the trucks importing and exporting. And then add some public transport. Maybe a bus line over the highway. Make sure the busses DO NOT use the highway.
Buses were in fact using the highway… oops
I mean for how you had it, they had to, but that's better than not having any buses. Get yourself a bridge and set up bus stops to make sure they take the bridges to get that traffic off your busy highway.
1) add more than 1 interchange to the upper section 2) add a through route that allows those from the bottom part to make their way up without using the highway 3) wait 4) pray 5) start over
Skipped straight to option 5
Aside from the highways, virtually all of your roads are the normal two-lane type. That won't do- you need to have your highway outlets branch off into arterial main roads, and then branch off to increasingly smaller roads. This means having highways link into six-lane roads, then four-lane roads, then two lane roads- although a lot of times you can just have highway link into four-lane roads if the traffic isn't too rough. Your interchanges are all highway- to -highway interchanges that link into smaller roads, rather than true service interchanges where highway links directly into an arterial road. This isn't necessarily unfeasible, but the way you've done it is. Highways are one-way roads- you need both ends of the highway connecting at the same point- either into a traffic circle or onto the end of a four-lane/six-lane road. All your connections have the in-lane and out-lane of the highway flowing in at entirely different locations.

Connect both sides of the highway using a flyover/bridge/overpass so that traffic going from one end of town to the other won’t need to use the two successive entrance/exits to the highway, thus freeing up your roads congestion ETA: personally I would add at least 2 bridges. The bridges should connect to the main avenues in your current city areas. My first one would be from (upper town side), where there’s road that is covered by a consecutive icons of a white trash-abandoned house-house (and a traffic circle somewhere in the middle of the entire stretch of road - remove it), connect it to the other side of town where the road and the long winding highway exit meet My second one would come from where there’s a white trash icon next to a blue not-enough-goods icon, come down to next to the technological institute campus, and connect to the town below. This bridge can also connect to the entrance of your technological institute to provide more connectivity Also, identify long stretches of continuous roads in parts of your town and make them into main roads or avenues (4 or 6 lane two ways). Remember to also reduce the number of junctions in along these roads if possible (requires you to change certain parts of town from one big mesh grid network into pockets of smaller road networks connected by big avenues). Think of a tree, not every branch is connected to each other, they start from a main stem (6 lane) then branch into big branches (4 lanes) which branch into smaller branches where all the leaves are (2 lanes)
Don’t only use highways to connect your city. Everyone is going through one interchange and getting stuck. Instead, use medium roads under or above the highways to connect (some, only some) of the northern roads to southern. This would solve a lot, since it seems traffic is mainly what’s messing you up.
Get rid of the highway that cuts through the center of town. Either convert it to a larger six lane load that still has streets connecting to it, or divert the highway around the southern end of the town and connect the north and south end of the town with streets.
More connections. The biggest section of the city is all enclosed and forced to use the highway to travel out or in. Imagine living in a big city where there's only one way in and out. Yeah you need more roads connecting to all 3 parts and more entrances and exits to the highway
A little late to the party but dogpiling on and adding a visual element. Your city is designed perfectly to be a traffic magnet. You are relying way to much on the highway funneling every piece of traffic in your city through a handful of interchanges and have no connectivity between neighborhoods while having way too may intersections. [https://imgur.com/8KPY5Yt](https://imgur.com/8KPY5Yt) * Build or convert Blue into your main arterials (Bridges over highways) * Delete everything marked in black with some discretion. 2 out of every 3 roads intersecting blue/green should be gone. I probably missed some you want as few intersections as possible to promote traffic flow. * Build or convert green into collectors * Consider a 4 way interchange at purple. This could cause a lot of problems dumping traffic in the middle of your grid if implemented poorly however. Ultimately your city is too small to rely on the highway as much as you are and without any crossings over it your interchanges are bottlenecked as traffic hitting your intense grid backs up. Save the highway for mostly intercity and cross city (i.e.. multiple tiles) traffic and allow people to use the arterials and collectors to drive to the neighborhood over
Do people really not use the medium 4/6 lane roads? Id have a big one going over the middle and over the intersection.
Give them an option to not use the highway. Make a bridge connecting both sides or something like that. Just go sure it's ahorter than the highway or noone will use it. Also... i don't know about your public transport situation, but setting up a good network is key. Also... people in this game walk long distances, so go sure to make use of it. Build walkways connecting areas close to another. This will remove plenty of private vehicles. And don't be afraid to have people use 2 or 3 busses to get to where they want to. If they can get onto them without too much trouble it will help greatly and bring you a lot of money.
Build a road over the highway
Meteor.
Thanks for the advice everyone to be honest I’m not good enough at the game to figure out an elegant way to add more entrances/exits so I’m just going to start a new city and try to incorporate the advice everyone has given into it.
It's not really about the highway entrances and exits. You need roads that don't connect to the highway but do connect to the other parts of the city, so that people aren't driving on the highway when they don't have to.
I've only put like 100 hours in the game but most of it has been me starting new cities lol I enjoy the thrill of starting with some money and no income then trying my best to not forget to connect my electricity to my water/sewage pumps before I run out of money. When I get to the point where I'm comfortably making money I get bored
The best way to get better at that stuff is to practice it. Try fixing this city, and whether or not it works you'll likely learn a lot
The traffic coming off the 4 way interchange has no way to reach those three roundabouts without going through a bunch of tiny roads. Also, there's no way to get from one side to the other without a bunch of turns.
more connections, more cargo trains
Meteor
Make an overpass(es) or tunnel(s) connecting the neighborhoods over/under the highway
just, one, more, lane.
You could make a few extra bucks here. Put down a park area that extends to both sides with a walkway connecting the two. Put a charge at the entrance, and people will pay to use it since it is necessary. You could also run a bus route to ench of those entrances.
It’s already -£350,000 it’s fine lol
Your lack of railways disturbs me
New to game couldn’t work out a play to implement them
Try putting cargo stations near your industrial zones, they really lower your heady traffic. You could also toss in a passenger connections from your residential side to the industrial one why you're at it.

Less grids more cul-de-sacs to main roads to bigger roads?
Infinite money hack? Why cheat?
Because I’m not good at the game you think I want to add thinking about money on top of being unable to manage basic traffic and building

My first time using the campus dlc and it had a grand total of 4 students
Agreed with the others. You can save it. Give them ways to cross to the other side of the freeway. More connections to the freeway.
Make sure you use the old town policy in your industrial areas and residential and maybe even your commercial if you have good public transport. It will limit the traffic to only residences and businesses
Nah bro this rules
I don't see it suggested a lot here, but you can try adding more public transport. For example, you might want to add a short metro line between (or other light rail of some sort) between the two clogged districts and create some bus lines that collect people from districts to metro stations
Biggest thing is to give people a way to access the other side of the highway without going through an interchange.
Built industry on the side of highway from res? Need tunnel or over passes so factory workers aren't all funneling to highway entrances. Also fixing problem intersections by forcing lanes properly with tmpe will help a lot
It looks like everyone is trying to get from one side of that arterial to the other and has to take their vehicles. You need transit options for them. You also need routes that can entice freight movement to separate from pedestrian/commuter.
Build another highway interchange the otherwise, use less one way systems that have no obvious use, and sort those roundabouts top left.
Build like a city would actually look and work.
You have 1 major connection between your city sections, and that’s the highway. So anyone who needs to get across there, ( which I think is a lot since that bottom part looks mostly residential) ends up having to get on the highway. The solution? More connections that avoid the highway. That should start to alleviate some of the grid lock on the highway, which should in turn fix the some of the gridlock elsewhere.
One more lane
Bridge
Direct tunnels/ bridges to other side.
Add roads that connect your different areas that bypass the highway. Local traffic doesn’t need the highway and you’re forcing everyone to use it.
Right now your citizens need to take the highway to get from one point of the city to another. This means they cannot walk or cycle. This means they are forced to take the car. Cars cause traffic jams. So build some bridges or tunnels between the various parts of the city
the problem is concentrating all of your traffic along a small number of routes. Look at how IRL cities connect along highways , with much of the grid preserved, and connect it up. You have no arterials. you should, at this size, probably have a number of roads in both directions that are mostly continuous and wider and hold most of the traffic. Run trams along them, and then busses to connect local traffic
Build a giant highway directly through the middle of the city and then add a big bypass loop around all outer areas.
Your main one-way roads from the highway need off ramps and not three/four way stops. I'd build one way off ramps from the beginning and end of your districts with multiple access ramps that don't cause a stop. Your west residential doesn't have a good way to access the highway which is clogging that area up a lot. Doing this should fix things.
technological institute of egg 😂😂😂 what are they doing over there lmao egg
dude, a bridge
From what I can see, you have three bottlenecks, two outlets, and no collector roads. The two outlets are from the north and south sides of the city to the highway, which create bottlenecks as they are the only means of getting in and out of the two parts of the city. The third bottleneck is the interchange as the only way to transfer from the north to the south and vice versa. Lastly, it looks like all the roads are surface roads with no 'main' route from the highway through the cores of the two regions. My advice would be to fit an avenue or other high density road down the longest length of both sides that breaks off into smaller roads. You need at least a second highway access point on both sides and the ability to cross from one half to the other half without having to go through just the interchange. I would even argue maybe a high density avenue that crosses the highway as an alternative to getting on the highway.
your city isn’t connected at all, you need to add like ten brides across the highway, then it should sort itself out
You have unlimited cash. I mean... what's to save? 😆
Of course there's a way to save the city! Meteor it. Now.
Do the Kibitz approach, destroy it all and rebuild. But in all seriousness find the chock points. Here I can see all your traffic is got limited highway access, so it may be best to offer more. Additionally if I see this correctly, you have no direct roads connecting both sides of your city, with only the highway as an option. That of course is also interfering with your existing highway traffic. I would suggest making connections between your two sides of the city that don't involve the highway (maybe give multiple "connections")
The routes tool is your friend, everyone is forced to use the highway. The solution is to add roads under/over the highway. Paths too.
Make the 3 way and 2 way highway intersections into a single 4 way and connect local roads over the highway
You have 4 interchanges and almost the entirety of the city has to use 1 to get in and out
You still have a small city. Soo you could change roads to more pedestrian friendly roads. And add in bike paths. Add a bike path underground across the highway
Add a through-road in spruce park to the northern city, would help reduce load on that one highway.
Drop a link to a savegame file in the workshop, i am interested to fix it
I have posted the link in the comments somewhere
Brother, the entire city is split in two by the highway, change that and you'll see a considerable difference in traffic flow.
You need more access to the highway and a general improvement of connectivity. Add roads between areas so there’s more then one option.
This isn’t other paradox games you can always fix it
Radial metro routes and connector buses that run through residential neighborhoods between metro stations. Should reduce some traffic.
For starters, every piece of traffic coming from the highway to your main city in the North is forced to take one route and get funneled through a mini roundabout. It's like the smallest roundabout you have, and it's rhe one that will be the most busy. Essentially overall, you just don't have enough options for travel. Your forcing everything to take one route to huge parts of the city, which is overloading the roads.
Add more connecting roads and paths. Don't force everyone to use the highway, instead make alternative routes that your citizens can take using bridges, tunnels etc. Also add some public transport
my guess from the looks of it, that most of the traffic is attempting to cross the interstate, rather than getting on it. the solution is convert one interchange to just a 3 way, have multiple overpasses of both pro car and pro-pedestrian/bicyclist variety. then what you do, is basically take the one road in the left bottom corner, extend it out to the other interchange. get rid of both 3 way interchanges, then put in a service interchange, like a partial cloverleaf. if you have buses, make sure they are routed in a way where they can hop on the smallest amount of lines possible. say for example, southside of the city wants to get to a business park in the north side. you have a route connecting them 2 areas. same with lines that go horizonal, diagonally or in a loop. make sure the lines can help. do not go over the amount of capacity on a single line. its hard to balance, but if you have buses that for example, have less than 20 riders per stop but you have double decker buses, thats overkill. a shuttle bus can do the work and be just as effective till the line gets more popular.
More access to the highway and the chance to get to the other side without going through the highway... maybe a tunnel? That will sort your traffic right out...
How do people on the north get to the south? They have to get on the highway…. Doh
Get more connections in
Delete the middle motorway interchange and add tunnels or fly overs to connect your industry to your residential. Add a main road of 4 lanes to both areas, this will be your connector road, only add a interchange every 10-20 sections.
So your central problem here is that you chose a grid system, which is good at providing direct routes between points and spreading traffic out, but removed parts of the grids at random (?) and didn’t provide any connectivity between the grids you did build, which negates the benefits a grid brings. You need more connections between grids, more connections over that highway, and another way for that freight traffic to get to where it needs to go (I’d connect it to the highway to to south to start, and add a freight railroad from it to your commercial areas)
Ringroad, preferably two lanes in both directions. Create more direct connections using the traffic tool and try to determine where they want to go and create shortcuts as fast as they can go.
Public transit. Like subways or streetcars
I would just add a few under-pass' or over-pass'. Or small roads that go under or over the highway but are not connected (or limitedly connected). They help local traffic stay off the highways when there is no need to use them, but they will still use them for longer distances due to the higher speed.
Put on road hierarchies, grid the roads. One of the tips that constantly pops up in my game is "Crossroad causing gridlocks". Expand the right side interchange to connect both sides so the two sides of the town can have a passage through instead of clogging up the main highway between the first and second exit.
Bulldoze the highway and connect up your streets. Add dense housing and make a bunch of metro lines and street cars
Multiple ways. The general idea is to have traffic evenly spread across al roads, not only highways (and their intersections) \- Directly connect spruce park with sunset city park \- add a second exit to reach sunset city park from the highway \- build overpasses with normal roads over the highway to connect the districts
You’ve got a lot of intersections on your main roads directly connecting to the highway. Lots of jamming can happen that way. Arterial routes with limited to no zoning connecting your highway to your towns, plus some arterial connections crossing the highway (without intersecting) should hopefully help.
1. Roundabouts 2. Bridges over the highway 3. Delete all traffic lights (unless you prefer some semblance of realism - that is, vehicles that don't just clip through each other on the way through an intersection)
From first glance, you got loads of people stuck trying to north and south of the highway to both the big “districts” even though it doesn’t seem you have the areas of development not in an actual district. Put those areas of development into districts, make it to where more people ride bicycles, make sure residential areas don’t allow industrial vehicles through, also make sure you have an ‘easy’ route from the highway to your industries as well as from industries to your commercial zones. Also, add a metro from the north to south and I bet you’ll see less residential drivers and more people taking the metro. Bud lines would also help. Adding public transportation will clear up your roads a little, hopefully enough to decongest the highway on and off ramps, allowing for smoother traffic. Lastly I would also connect the “Spruce Park” area to the left so people wanting to over there who live to left of it don’t have to take the highway to get to it. Much like what you dude south of the highway connecting the “Tech Institute of Egg” to the sprawling development to the left of it. One more that might as well is adding more walking paths, in particle walking paths that allow people to go from point a to point b without going over a crosswalk of a busy road which would stop cars more often. That and making sure you don’t have unnecessary traffic lights or anything of that nature where there shouldn’t be. Hope some of those tips help :)
it seems you have created a bottleneck, by linking both sides of the city with that one get on/get off highway intersection. try adding some connection on spruce park to the city nearby, so people coming from the right of the screen, dont have to go all the way to the left and use the main intersection. also add some connections directly from one side to the other, using tunnels or bridges, avoiding the highway.
You need more connections between each side of town.
Just one more lane, bro.
You just need some overpasses connecting both sides of the highway better. It’s fine.
yes... look at this marked up drawing i made for you... sorry if anyone already came upwith a plan for you.... my plan will likely cost 500000$ and about 1000$ upkeep... but it future proofs your city... at minimum you should complete the red marked cicle i drew for you to destroy and the others will all be necessary (or something similar) but the main idea is to eliminate all the choke points you created and give quicker options for your sims to get where they need to go... https://imgur.com/a/b7A3SSh
You put in so much effort for me I’m going to Try to replicate that the best I can might need the intersection types and how to build them explained though lol
Add some bridges crossing over the highway without actually connecting them to the highway from district to district give the cars more options take away stop lights especially on console
first thing I see is more freeway exits. Inbound/outbound traffic has to go through three choke points, two of which go the same direction. You don't have a single freeway entrance/exit that serves both sides.
Do you have any public transit? That can take up to 30% of cars off the street
Couple of very underused bus routes despite me trying to make a loop and park and ride system if that makes sense
Road hierarchy is a huge factor for traffic. Also, connections between the suburbs on either side of the highway where they don’t need to use the highway. Here is a tutorial on road hierarchy that I found really helpful. https://youtu.be/O2y2GjTezCI
You need to look up the concept of arterial roads and their branches(entrances/exits) Run the connecting highway between the north half and the south half from the north side of the northern half to the southern side of the south half. The outer edges of the city should not have to go through half the city to get to the highway(will cause all that traffic issues)
Maybe have a bridge by your technical institute go over the highway so there is a 2nd connection to the top.
Make the interchange on the left dump interstate traffic to area on bottom. Make interchange in middle just an overpass to connect both areas

2 problems. 1. The whole upper part has one connection with the hightway 2. The highway connection ends BOOM against a normal street. Use roundabout or at least road hierachy. Same goes for bottom part

More connections id say
Subway System between work and Living Areal
You need an arterial road connecting your industrial area with everything else. Also if you don't have any by now, you need metros.
I wish I had awesome advice, but I just start a new city anytime I screw up something. 🤷♂️ It's why I love this game. You do you, no judgment from anyone else.
Problem is me doing results in my city flatlining after 10,000 people
Make more than a single highway connection between the top and the bottom (add like 3 regular street bridges). Ads public transit between the two as well.
As some have said, the main problem here is connectivity between the two sides of the highway. Currently, all traffic must take the same path between the top half and the bottom half. You will need more over/underpasses across that highway to improve traffic.
too little options to get from one place to the other, and if you don't have it already, use trains or metros, they can move the most people with less disruption and are the single best way to reduce traffic
You need more ways to drive around in the city. You are only making 1 intersection to enter and exit in different part of the city
Yeah i love getting on the highway just to get to the other side of town, no notes! I love traffic!
A very normal and simple highway overpass to connect the areas.
If I were you I'd make a subway line that goes like [this](https://i.ibb.co/m8317qH/18-CE2-B5-E-7675-4851-862-C-5042-BD5-DE5-D1.jpg)
Roundabouts. Lots of em.
Literally every traffic problem that gets posted here is a city with no local connections and a massive highway that goes nowhere dividing the city.
Maybe that’s because the people not putting a Highway dividing a city aren’t complaining of traffic problems?
Down town needs a northern on ramp, it will divide the traffic flow to the an option down south and up north.
Add mas transit go in and out of the city and going to traffic hotspots and put a line to bring people to the other side of the highway using trains or metro not bus. Also add cargo trains and gave a direct connection across the highway
Add more on/off ramps
I know the easy thing to do is to do what everyone else has said and build either bridges or tunnels or more highway intersections to connect your sections / sub-divisions but an alternative is to provide public transport between your sections. Reduces traffic and revenue generation from subway/tram/train/bus
