quick setup of meduim prioirty road

[kianzarrin]

Introduction

In #621 (comment) , #621 (comment) , and @aubergine10 requested an alternative high priority road (lets call it medium priority road) that does not allow pedestrian crossings but does allow going through blocked junctions (@aubergine10 what about far side turn?) .
I created this uncommitted branch that uses alt key for the said medium priority road for demo.

The problem is the number of modifier keys is getting out of hand. I think too many modifier keys and state machines can confuse users.

So the question is what should be the UI that supports alternative priority roads for user?

related #557 #710 #691 #711

Proposed solutions:

• Put it in road selection panel (Mass-edit road selection panel #631)
• Create a GUI panel for priority road GUI pannel for prioirty signs #711
• an in game panel to select which rules we want to be affected like the roundabout mod:

@aubergine10 In the medium priority road I assume you want:
1- going through blocked junction
2- pedestrian crossings on the main road

Do you want cars to be able to do left turn? (I think you should otherwise cars have to go round the city to turn left.)

Yes to 1 & 2. And yes for far-side turns. That should be sufficient to differentiate the medium vs. high priority road.

Maybe we should also default to medium priority if user has selected a 'small road' (or high priority if its a medium/large road)...?

I worry that if users go round splatting their roads with the high priority settings that their city will be a nightmare for pathfinder.

Also, on the high priority one we already have, I assume that traffic lights will enable vehicles to reach the other half of the city? (I can't remember if I tested that yet but will check next time I'm in game).

EDIT: Only if they put default timed traffic light.

Nope!!!! see Warning! you will need a collector road (EDIT: having a clear NODE button can help a lot here :) )

So I am worried about that to but I don't know what to do about it. The user should limit the range of the high priority road to exclude one road at the beginning or the end. Maybe I can do a path-find my self to see if the car has to drive too far or not. if the path is too far away then I can pop-up a guide message (hey did you know with these new settings your car has to drive all the way around the city now? please give your cars more options and create a collector road).

But even if the cars are driving all the way across the city its still better than some nightmare setups that people have with too many junctions close together. At the very least the traffic can flow!

Yes to 1 & 2. And yes for far-side turns

Got you!!!!!! this is in contradiction to #424 . If 454 #424 is implemented and far side turns is enabled then cars should nomraly keep clear of intersection.

If #424 is implemented then there is no need for a medium priority road (as you described above) and you can simply use the yield/stop button.

in any case #889 should fix this issue for the most part. Should I close this as duplicate of #889?

In #889 I'd ideally want to be able to define settings for high priority and medium priority separately, and then maybe have Alt + Click modifier to decide what clicking the priority road button does. In fact, in that situation the distiction would be 'normal vs. alternate' rather than 'high vs. low' - essentially I have two profiles to choose from, the normal profile (just normal click the button) or the alternate profile (Alt+Click button). The same could apply to roundabouts; eg. I could set up two profiles, one for big roundabouts, one for small roundabouts and choose to apply the alternate one with an Alt+Click.

Also, not sure why you referenced #454 "Trace in RELEASE build"? Did you mean #424 ?

[kianzarrin]

where do you setup the alternative profile though?
and if #424 is implemented you cannot have what you described so at least the issue has to change. I should change issue description.
But if we cannot setup enter blocked junction I think the alternative profile would not be so useful anymore. this also means in #889 I might not actually implement the alternative profile to simplify things. Instead I provide a bulk edit button which is fully customizable.
