Anyone built an advanced one way road system?

[Sailing_Bob]

Hi,
I am testing various solutions on building a city between two highways were the idea is to have all the traffic flow through the city from one highway to the other using only one way streets. Any one tried that and have some screen shots to share?

Your service coverage would be sevierly hampered since they can only tracel in one direction.

I don't have a solution for a complete system, but through experimenting I've found that it helps to alternate between pure incoming and outgoing traffic in intersections to avoid crossing traffic stopping the flow. Something like this: Example[i.imgur.com]

I do things like this:

two one ways to get in, one big road to flush everything out. It's not without its problems and service coverage can get a bit tricky though. It's a good idea to make the middle of less transited roads two-ways.

The second one uses two ways to get in and out, and the district itself is one ways for the circular roads and alternating one ways for the radials. Just on the tips though, middle is two ways so people don't have to go around the whole thing.

My way is:

Top and bottom: Highway->Offramp->2-lane 1-way street->Offramp->Highway.
Regluar 2-lane 2-way streets between.

The citizens can drive around their whole neighbourhood using right turns only.
No trafficlights.

In the end one ways will give you a harder time than building well built systems.

Wow you have some pretty impressive city building skill :)

My city look very boring compared to yours

[Sailing_Bob]

Impressive! Thank you all for sharing your excellent cities.

Thanks I know! My findings so far is that the more one way streets you use, the higher the total cost of services. Maybe a system with only one way streets are to expensive from a service point of view, or is it? I think for instance the pattern MK_Blackbird shared is reallyinteresting.

This looks really interesting, thank you for sharing that pattern! I am going to loan that idea from you and do some testing :) Cheers

Oh, well I wouldn't call them "excellent", but it's the system I managed to get working. But at any rate, my advice would be to combine one ways (with overpasses to prevent crossings) for critical accesses and two-ways for easy access on the lesser ones. Just switch to the traffic layout, see where there's congestion and figure out where the cars causing them are coming from and where are they trying to get and make direct roads so they can skip to destination without clogging other roads. Also make sure you put one-way mergers and branchings on the proper side of two-way roads so one lane doesn't have to completely stop to let the cars on the other one pass.

Thanks though :P

Thanks for sharing! I too have used street systems were I (virtuallly)only use right hand turns, but I get traffic lights on all my crossings. What do you do to not get traffic lights? Is it the combination of certain types of roads?

Define 'well built systems' :)

I made a new city based on combinations of one way roundabouts connected by two way streets which strikes a balance between advantages between one way roads and services coveridge. This way traffic can only turn right in virtyally all crossings. I use some of the roundabouts to place special buildings in which has worked resonably well.

There are some heavy traffic in some of the major roundabouts but never becomes an issue. Service coverage is good.
