Most likely, the vehicle has already arrived and thus left the simulation. You can either - check for the vehicles presence by confirming its presence in traci.vehicle.getIDList - monitor all arrivals with traci.simulation.getArrivedIDList - handle the exception with 'except traci.TraCIException' (the simulation will continue to work)
