I am doing a research that includes an intersection. Simulation should be done by SUMO, OMNeT++ and Veins. when an emergency vehicle is approaching to the intersection the state of traffic light should be changed to green for that road after crossing the state should be returned to the previuos state. I have generate XML and SUMO files also some codes on OMNeT++ but the state of traffic light cannot be changed. I think even onBSM function doesn't work!!! I would be thankful if someone can help me.
