Hey guys,
I'm trying to trigger the rerouting of a vehicle via TraCI in python, using
the traci.vehicle.rerouteTraveltime function. It seems to be causing an
issue with an assertion 'startLane !=0' in MSVehicle.cpp:1932. Going
through the backtrace, it seems that the current Edge of the vehicle
doesn't contain any lanes. Have any of you run across this issue before?
super simple python script:
import traci
step = 0
traci.init()
while step < 1000:
traci.simulationStep()
veh = traci.simulation.getLoadedIDList()
if len(veh) > 0:
traci.vehicle.rerouteTraveltime(veh[0])
print step
step += 1
traci.close()
backtrace of sumo started in gdb, with --remote-port 8813 option, a grid
generated using netgenerate, and trips generated via randomTrips.py.
Simulation started with time: 0.00
sumo: MSVehicle.cpp:1932: void MSVehicle::updateBestLanes(bool, const
MSLane*): Assertion `startLane != 0' failed.
