Road junction options needed?
Since a lot of this game revolves around traffic control...

I'm just trying to get some clarification about more detailed road junction possibilities and then maybe the need for some more options.


As far as I can make out there is no way to manually alter things like when a road joins another road a stop junction/crossing is automatically made that covers the whole junction for all roads concerned.

In other words... it does not seem possible to make a *no right turn* or a *no left turn* possibility for the joining road (and thus making it possible for traffic on the opposite side of the joining road to be free from any kind of stop/crossing or any traffic crossing in front on them).

On small 2-lane roads it could be argued that making an automatic crossing is valid, but on larger six-lane roads not allowing for a more complex flow of traffic seems crazy, since large roads often have exactly the kinds of things I am talking about: ie a way for outer lanes of traffic to not be affected by traffic coming from other (inner) adjoining roads.

Maybe it is possible to do this already, but I have not found a way yet.....?

If such a thing does not exist in-game it seems this would be one addition to the road mechanisms that would make a lot of difference.

Also why do roundabouts have crossings to the middle island? That really makes no sense at all.

Because some roundabouts are large enough to be zoned in the centre. So the option is there.

There is a small collection of traffic (intersection) rule to the base game this is true. This is a simulator so not all traffic rules from all countries have been crammed into the game. It is challenging at times to figure your way out of some traffic rule issues but being a game creativity is the key.
Personally I built (just last week) an intersection in where only left turning traffic will need to stop for a red traffic light (vanilla build).
It would be cool to have more rules to mess with for sure in the base game. There are hidden functions such as multi-state traffic lights you can construct and different types too. Where a four way intersection can have up to four separate traffic light states (vanilla build) but the more states the longer the light and can cause de-spawning at the front of the traffic light for those waiting the longest for the green light.

I agree with the OP, I can't build realistic highway exits because of this logic. For example, I merge two exits at a six-lane road, but I can see cars taking a left turn and cause traffic congestion because that exit, *sigh*, is designed for right-turns only.

The two-lane highway is useless because of this.

Yes that kind of thing happens a lot and it's very difficult to stop.

The only way to counteract that seems to be to make roads one-way, but then that might mess up what you were trying to do in the first place.

In vanilla game, the angle of the junction determines whether the vehicles can cross over to other side of road or only go straight on.

You can use "Traffic Manager: President Edition" mod (Stable version is recommended) to get much more control over junctions - you can route lanes (or just change lane arrows), you can set advanced priorities (stop, yield, priority signs), you can customise traffic lights, allow turn on red, etc.

There are a number of "vanilla curb" assets in the workshop you can use to create medians across your junctions (you'll need mods like Move It, Find It, etc). Alternatively there are now some road assets where you can toggle medians at junctions by turning traffic lights on or off (like the one shown below; that author has several similar assets). Note that you will still need mod like Traffic Manager to control the lane routing, otherwise vehicles will drive over these medians.

The angle doesn't do anything. When I place a highway exit that is realistic looking, cars still take left turns and cause traffic congestion as only one car can turn left at a time, because the angle is too sharp to have left turns.

That is a problem for us on the low-end or medium-end PCs, the features we want is on TMPE, which eats a lot of CPU power, I would have accepted if some of TMPE's features were a seperate mod, not all-in-one (I only use TMPE because of the blocked intersections thing, yet I can still notice my game runs slower because of TMPE, so I had to remove it).

The sharp exit I am talking about can be seen on this video, at the beginning:

EDIT: Just watched the vid; those highway junctions weren't sharp enough.

If the angle is sharp enough (which might need mods like Fine Road Anarchy, I didn't mention that above), it affects which lanes are connected at the junction. I've seen this myself, it definitely works but relies on quite sharp angles. Even the lane arrows will reflect this effect.

Another alternative is to place two one-way roads in parallel - this works really well and allows a great deal of customisation flexibility in the 'median' area between the two roads.

Thanks for posting the mod links.

I think, however, that such an essential feature needs to be made available without the use of mods (which as we all know can often cause side-effects, compatability problems & performance issues). Every time a new DLC is made for this game there are problems with mods being compatible with the new update.

Such a fundamental road-traffiic mechanism used a lot in real-life to control traffic flow.

~

The placing of 2 parallell one way-roads is not actually always providing a solution since that that limits you to using highways (which cannot be built from) or either low-traffic roads or high-traffic roads.

~

It would help a lot if medium roads with central blocks/areas (like the medium avenue type roads with trees etc) if there were be an option to retain the integrity of the middle when placing a road junction.

Iv'e subscribed now to that workshop item from RyanCat which actually looks really useful and seems to do exactly this (retains the integrity of the middle isle). He also has 4 lane road junctions that do the same thing.

Thanks for posting that. Much appreciated.

I have played CS for coming up to 240 hours now and this is one aspect of the game that I have never found a satisfactory solution to.

You can turn off some of TMPE's features in the options menu to improve performance.

Update.

RyanCats assets sadly do not work without TMPE

These screenshots show that even though the road middle should theoretically stop traffic from moving accross .....it isn't!
