Vanilla traffic light is stupid on T junctions #544

Open kianzarrin opened 4 years ago

kianzarrin commented 4 years ago

Screenshot (3) In the picture above the traffic light has 2 phases. phase 1: the tree road and the basic road have green lights phase 2: the road with grass has green light. during phase 2 the road with trees should be able to turn right. there is nothing blocking it. Can we fix the functionality of the vanilla traffic lights?

Notes:

It is possible to allow right turn at red traffic light but its tedious. Also this method has speed disadvantage because right turn at red light is slower than right turn at green light which is intentional because cars have to check if they have to yield (although in this case no car is coming).
- Its possible to fix this with a timed traffic light but its too hard. much easier for the user if we fix the vanilla timed traffic light.

I vaguely remember that the vanilla traffic lights gets even more stupid if there is no straight segment.

I totally agree that default traffic lights should be more intelligent.

Turn on red feature can be applied to whole city via TM:PE mod options (Policies tab I think?), so does not need setting per junction in that scenario.

Also, what about vanilla traffic lights when there are roads with dedicated turning lanes?

No this is not what I am talking about. Turn on red is slower than genuine green light. Sorry if it is not clear I tried to make a video to explain what I am talking about but the game crashed for half an hour and I gave up.

What I mean is that if there are no cars coming from the other roads because they have red light, then turning right should have a green light.

Aren't you forgetting the pedestrian crossings? During phase 2, pedestrians can cross the road with the trees, so the default makes sense to me.

kianzarrin commented 4 years ago

@graup in a + junction vanilla traffic lights have 2 phases and cars always go over pedestrian crossings the road. so that is not a problem.

Sorry for the late response. I took me a while remember this.

graup commented 4 years ago

@kianzarrin Ah, yeah, makes sense. I was thinking that if turning-right was green, pedestrians would be red. But of course, they can both be green.
