A1) possibly your vehicle has a different vClass from the defaut vClass="passenger" assumed by simulation.findRoute. You can avoid this by calling findRoute(from, to, traci.vehicle.getTypeID(vehID)). If that doesn't solve it, print the found route and then insert a vehicle on this route via XML inputs for a more comprehensive error message.
A2) the function simulation.findRoute uses the global edge travel times whereas you only penalized the vehicle-specific traveltimes (traci.vehicle.setAdaptedTraveltime). Use traci.edge.adaptTraveltime instead. The values of vehicle.setAdaptedTraveltime are only used when calling traci.vehicle.rerouteTraveltime. A3) Either by calling edge.adaptTravelTime(traci.edge.getTravelTime) for all edges or by using findRoute(..., routingMode=traci.constants.ROUTING_MODE_AGGREGATED) - see https://sumo.dlr.de/wiki/Simulation/Routing#Travel-time_values_for_routing A4) you cannot reset edge traveltimes at the moment ( see https://github.com/eclipse/sumo/issues/5827 ) but you can limit the scope of the change by setting the begin,end arguments (or just setting it explicitly to length/speedLimit). regards, Jakob Am Do., 11.
