Hi, I have a simple TraCI scripts that add a vehicle to a network composed of a single long link.
The vehicle is added correctly, but when that vehicle reaches the end of the
link, SUMO crashes.
The script is as follows (also attached, with the rest of the required network
and config files).
Why is it crashing?
import traci
sumo_binary = "sumo"
sumo_cmd = [sumo_binary, "-c", "single_highway.sumocfg"]
traci.start(sumo_cmd)
step = 0
route_id = "!type1"
while step < 300:
traci.simulationStep()
if step == 50:
print(f"Adding vehicle at {step} route {route_id}")
traci.vehicle.add(vehID="added_vehicle",
routeID=route_id)
traci.vehicle.setColor(vehID="added_vehicle", color=(255,0,0))
step += 1
traci.close()
The error when crashing is:
Traceback (most recent call last):
