[sumo-user] Edge-List is expanding unnecessarily when I reroute via trac

[Valentin Klamka <valentin.klamka@xxxxxxxxx>]

Hi,

I use Sumo Version 1.3.1

So basically I want to drive back and forth:

            if (traci.vehicle.getRoadID(vehicle) =='gneE28'):
                traci.vehicle.changeTarget(vehicle,'gneE11')
            if (traci.vehicle.getRoadID(vehicle) =='gneE11'):
                traci.vehicle.changeTarget(vehicle,'gneE28')
               

when I print (traci.vehicle.getRoute(vehicle)) I see that the Edges-List gets longer, the longer the simulation runs. But to save space I only want to save the edges which I need to reach the destination. I tried traci.vehicle.setRoute(vehicle,traci.vehicle.getRoadID(vehicle)) to reset the route, but it only appends the new edge to the previously traveled route. Is there a way to reset the route? If not, what is the reason behind it?

Best,

Valentin
