Traffic AI is still stupid

[What a disaster]

I've seen several posts with people praising the improvements to the traffic AI, but I think they may just be confusing improvements with less overall traffic. I already have over 30 hours in the game and I am constantly noticing extremely stupid and frustrating traffic behaviour. For example, cars feel the need to cut across 3 lanes of traffic 5 meters before the intersection, when they had plenty of time to get in the correct lane, which backs up the whole street. There's cars doing 3 point turns on the middle of intersections. Some cars will take stupidly long out of the way routes to get where they are going, even when the optimal route has light or no traffic. Cars still drive down to the end of cul-de-sacs to turn around when they have already passed an intersection that they could have used to reach their destination. I feel like even with TMPE tools, I would have to spend a lot of time figuring out ways to deal with the traffic because the AI is just not very good. Am I the only one who is underwhelmed by the new traffic AI?

Isn't it pretty realistic then, based on the things you said :)

On a more serous note, substantially better than in C:S1 but not perfect. For example in roundabouts, lane connections are a bit funny sometimes and cars wait far too long for their turn even if there is space to go in.

Traffic uses all lanes most of the time as opposed to just 1 lane, that is an improvement.

I saw huge influx of traffic at 6000 population, but dead traffic at 17,000 population, then back to 6,000 population amount of traffic. My roads are mostly congested that's because I got rid of the buses and replaced it with trams.

They all seem to like riding buses huh? *gets rid of bus depot* and bus stops.
TMPE took years in development.

Stop using mods vs. base game.

You do know that rush hours are a thing? Roads will be empty during the day time and nights, Morning and evening sees the most traffic.

Yes I agree, there is a lot of unnecessary "stop-and-go" where cars will slam on the brakes or even stop fully before turning even when the lane is clear. I feel like TMPE lane connectors would really smooth out intersection traffic, especially for advanced intersections, by forcing traffic to pick a lane further up the road from the intersection. This was one of my most used tools in CS1 and I feel that it would solve a lot of problem in CS2.

They use more lanes, but still end up picking the wrong one for their destination a lot of the time, which results in traffic jams at intersections. TMPE lane connector could largely take care of this. The base game (in its current state) just doesn't provide the necessary tools to deal with the AI. If they improve the AI or the traffic management tools, we wouldn't need mods. Also, TMPE gave us the ability to set specifically which lane leads where at intersections. Multiple times I've had to find workarounds to get the desired number of turning lanes, and I still can't control which lanes are turning only or combination straight and turning lanes.

Three-point turns in the intersection is just Tuesday where I live.

Frankly I'm fine with it and it looks like the people aren't complaining.

Using roundabouts on some intersections may also smooth this out too.

It's it's both better cause generally traffic isn't a problem. but there's one spot in my city where the traffic behavior is baffling. Nowhere else is as bad as that one spot and nothing i've done can fix it.

And the way it's borked changes each time it happens.

I think the cars try too hard to fill lanes.

Well that's a fair point in cs1 b4 quite a few updates/patches and TMPE you would get massive single lane ques on six lane roads.

There was 4 cars in a 5 lane road

Only if you didn't know how to lay down road network.

Yes? And I got empty 4 lane road sections during the day time. But at rush hour, there is a queue.

Biggest reason i bought CS2 is traffic management but yeah AI is not as good as expected.

- Traffic stops on the rondabouts to let the other cars pas. (normally you stop before the rondabout
- In some cases the tracfic stops a second on the rondabout. aven without any other cars. backing up all trafffic.
- Car enter a road and turn back after 1 meter. All other traffic yield for some reason. (result traffic jams)
- I don't care if one car does it but when 90% of cars change his line just infront of the stop sign, is not good.
- all cars that change lane sometimes always driving in reverse, creatingg traffic jams.
- AI does not always travel the best way. I mad a small alley-road next to the main road to have some extra lane for the traffic to enter parking spots. But everybody started to use the longer alley road.
- Fire fighters need to drive up norht, then take on left to reach to burning houses. But they decided lets take the longer, slow roads that are S-shaped. everybody died. all Hearse-cars were already pulling out the dead out of the fire.
- ambulances stop on places without ppl or cars/houses . just becaus
- car accident are nice but...


all these things above causes traffic jams. I could live with that but this also causes traffic to get stuck. aan most cars will disapppaer. So evertything does not matter. Its a immersion killer.



I fond out the best way to deal with lane changes make your road in sections long. not in pieces of a few meters. Specially infront of intersection. It will help a little bit.

And raised pedestrian walkways would be nice. They take up a full block to make and the pedestrians ignore them and use the crosswalks anyways. Biggest issue in game, along with not being able to create main roads with stops for othe roads but not main. And please give us move it mod.

I would say people cutting 3 lanes, u turns in middle of the road, and going through red lights is pretty real.

Just last week I seen someone on the highway drive straight through a red light. Thankfully it was night so low to no traffic.

This can be probably be lowered though too fix this issue

[Befitzero]

I will say its better than CS1 , one thing I noticed that often causes problems is cims crossing busy intersections. I kind of miss the mods that let you remove cross walks on some roads and being able to build walkways that bridge over your busiest intersections.

Parking lost I notice cause traffic back up too if you place too close to an intersection.
