can't make vehicles follow traffic light controls using mesoscopic simulation
Closed this issue · 7 comments
I use TraCI to control when traffic lights switch between phases. The general control is to remain red unless a vehicle has approached the traffic light. Then it will switch to green to allow the vehicle to pass.
My simulation models a large quantity of vehicles and simulates a 24 hour period. I started looking into using mesoscopic to help speed up the simulation. However, when I use "--mesosim True", the vehicles ignore the traffic lights because they jump over the nodes. To try to fix this, I also implemented "--mesosim-junction-control True", but the vehicles remain at the first set of traffic lights and don't move.

We have a test example scenario for mesoscopic simulation with junction control available. You can download it and compare with your own scenario to see where differences are.
@corinnegroth Did you succeed to make the vehicles respect the signal?
Closing for inactivity. Just post here again if you still have the same problem.
Thank you for your response. I was out for 3 weeks because of the holidays and illness.
Unfortunately, I'm still experiencing the same issue, even after looking at the test example.
@corinnegroth Then you can attach a small working example of your problem here.
Currently, this configuration obeys the traffic light control logic I've implemented using TraCI. Again, the general logic is the light should switch to green when a vehicle is approaching; otherwise, it should remain red. However, when trying to implement mesosim capabilities, it appears that the vehicles remain stopped until the end of the simulation.
Some remarks:
- the switch is named
--meso-junction-control(not--mesosim-junction-control) - use edge-related TraCI calls to detect vehicles (because lane-based/detector-based calls have no meaning in mesoscopic simulation/no approximative fallback solution has been implemented for them)
