We've talk a lot about public transport and so. But the main transport of a lot of city maintain to be the car. So I created this thread to talk about road in Cities Skyline, and in which direction they could improve the system ( considering it's the same as in CIM2 )..

Something missing from Cim2 is the bridge structure. There's so many beautiful bridge out there, but we only have viaduc in the game. I think it would add some aesthetic aspect for a city, even a landmark for certain city if we had more develloped bridge.

A usefull tool would be the ability to draw freeway in both direction at one time. In Cim2, to build a freeway, you have to draw it in one direction and after in the other trying to make the central median homogeneous and it's really hard. I know it, I made it. ^^ The median could be narrow or wide if the freeway is urban or rural and so. A cool thing would be to have a wide median and to add some railway in the middle to make it look like LA's metro line. Or in a further DLC, we could add HOV lane in the empty space or again simply adding more lane as the traffic become more dense.

I also seen in the closer view of Cities Skyline that there's only one type of road. And in Cim2, there was no local street. I would love to see a different sort of road which disabled transit traffic, have stop signs at intersection and no mark in the middle. This street would be use for residential area/ access road for building complex or industrial area and would only be local. They would have a low speed limit and the possibility to park on both side. These street could also be used as rural street in addition to bigger road. A street connected to road/avenue n so won't have lights and only give way's sign.

One of the big issue in Cim2 is the traffic. in many ways, gridlocks occure for some random reason as cars changing lane at the wrong time blocking all traffic. People only use one lane which is overcrowded., and many others. CO should really do something about that and change the patterns of cars especially on freeway. All lane of freeway should be use by car especially if the traffic is heavy. The only reason why only one or two lane have to be used is approching interchange, so maybe 500m before intersection, car would choose the correct lane, but NOT all in the same time.

Something really bad is that cars change lane when the traffic is block or they can't finish the movement because of cars stop and so block two lanes the same time. Cars shouldn't be able to make a lane change if they want to go in an obstructed lane, or if they wouldn't finish it as I described above.

Parallel flow traffic in the Bay Area.

A purely aesthetic construction are retaining wall. In Cim2, even if you just made a proper viaduc from the ground. Below a certain point, the land is just raised and take much place. If you want to build a sunken highway, some ugly cliff appear, and it should be replace by wall. The result would be cleaner and structure would take less space.

The turning bay is something I really want to see in Cities Skyline. I was surprised when I've seen they haded some of them in GTA V and I didn't understand why No one is making them in City builder game. Those lane are really needed to smouth traffic, and would solve a lot of problem. Left turns won't gridlock traffic if there's too much wait and median wouldn't be useless. I'd really love to seem them in CS. :)

Two different sort of approach for a turning bay.

And youself? What are you thinking of my idea ? What would you add to the game? What do you wish to see in Cities Skyline?

Thanks for listenning and sorry if it's hard to understand sometimes. I've tried to be as clear as possible for my english level.

Yeah, I know! These city builder games should pay more attention to road infrastructure. That's why I find only SimCity 4 with the NAM mod to be the best city game - turning lanes, different road skins, custom intersections and everything! But scrolling through all the hundreds of plots ruins the experience. So I thought how the Cities: Skylines could make roads awesome (and realistic), but for intrigue (and also because the developers will be back from holidays only then) I will reveal my idea with beautiful illustrations only after the 5th of January.

My idea would allow you to build the city you truly desire - from a city with wide boulevards for cars (America), to a city which prioritizes buses and restricts cars (Swiss), to a city which prioritizes bicycles and restricts cars (Netherlands). (BTW it's weird that no city builder game has taken bicycles seriously - that could have been forgiven in 2000 but not in 2015!) There would be generic streets for people not interested in the infrastructure part (so it wouldn't be complicated) but also a possibility for the enthusiast to create almost any street he wants! And the type of street, just like Cities: Skylines bus stops, sewer, electricity and other infrastructure, would influence happiness.
So, for example:
parking would increase happiness for all driving to-from that area
each car lane decreases happiness for the local residents (due to noise increase and difficulties crossing) but increases for all drivers using that street.
trees increase happiness for all using or living on that street
bicycle lanes increase small business happiness and decrease driver happiness

that's it for now

Was traffic representational in CIM2? or was it actual cars driving here and there, with actual AI making driver decisions? (SC4 is representational and so is CXL)

SC2013 tried but didn't execute to well. I fired up SC2013 the other day...cars making a left turn would drive right through oncoming traffic. So it looks like they removed left turn collision detection to fix the traffic problems. Cars don't have rear enders because there seems to be collision detection.

My firetruck instead of going into the free lane, just sat there while the city burned...

Anyone know of a game with actual cars driving like actual people (AI) not representational animations...?

Actual cars driving.
Main issue CiM2 had and that CS still has when looking at the stream (dev say they will try to adress it) is that the drivers are too likely to go in a specific lane when trying to reach the same place.
This result in 4 lanes road with 1 lane filled of all the cars wanting to turn right to another 4 lanes road when they could use 2 lanes to turn.
Or even when going straight, they mostly pill up on the same lane.

And there is little to no take over and because they all respect the rules, even if they go in 2 lanes, one will be blocked because of the rules.

Hope they have a dev session on AI.

I think its a interesting problem, driving is pretty complicated...its more than a A* or D* pathfinding excercise.

Wouldnt that line be the correct AI thing to do though? If everyone is going to the mall and if the mall has one entrance then everybody needs to be on the proper turn lane to get to the mall? You cant use two lanes to turn right, right turns have to be done on the inside lane. Unless the roads are marked for a two lane turn.

The problem is people who arent going into the mall but who are on the right lane should switch lanes. Right turns arent bad it is the left turns that are killer. Real life and in game.

Lol then they can figure out cars pulling over for emergency vehicles problem :)

The best I can tell you is to look at this stream @32:50. It's quick, so better use the pause button.

You will see a giant highway round about on which all cars are on the same lane despite the multi-lanes intersections.
There is a little bit more after the round about and you'll see it's not just in one place.

This was my biggest irritation with the Cim2 pathfinding.
A way to get around this would be to assign a speed and a takeover ability to a specific car and household income level. For instance, a sports car, likely to be purchased by a rich Cim, would have the ability to go faster and overtake other cars or butt into lanes at the last moment. Yes, irritating behavior, but probably realistic. On the other hand, a poorer Cim with a lousy old beater car, would not be able to go as fast and maybe respect the driving rules better - resulting, unfortunately, into a slower commute to work.
Not a perfect solution, but it could maybe prevent the pathfinding from having one used lane that is backed up for miles while the other lanes are lightly used.

I really hope this is fixed because it was one of the most irritating things of CiM2. I also hope they add in road upgrading tools so we can add lanes as they get busier. And the ability to choose which lanes do what, such as turn or go straight!

They've shown pretty conclusively that they don't care about the butchering they have committed to of even what was in CIM2, and completely ignores the concerns. But your hope for a single way to draw both carriageways of the motorway are realised; only you can't have any sort of lane control, it's 3 lanes or nothing, and with a median that makes American rural motorways with mandated 11 meter separation look less than wasteful.
