Re: [sumo-user] Rerouting by traci python

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

If vehicles perform automated rerouting based on the "device.rerouting" options they will use
ROUTING_MODE_AGGREGATED and ignore the values set with traci.edge.setEffort.

For details, see https://sumo.dlr.de/docs/Simulation/Routing.html#travel-time_values_for_routing

To route periodically according to custom weight values either

a)

- disable automated updating of aggregated weights by setting option <device.rerouting.adaptation-interval value="0"/>

- call traci.vehicle.setParameter(ANY_VEHICLE_ID, "device.rerouting.edge:EDGE_ID", str(TRAVEL_TIME))  for every EDGE_ID you wish to change (vehicle id is arbitrary but the vehicle must exist)

b)

- don't use device.rerouting

- trigger rerouting with customized edge weights (setEffort) by calling traci.vehicle.rerouteTravelTime(vehID, False)

Dear SUMO users, hello

I want vehicles to reroute according to the current road conditions probabilistically during the simulation with traci Python.

Also, I would like to modify the weight used for reroute to edgeEffort.

The code of traci Python I wrote is as follows.

while step < 86400:

    traci.simulationStep()

    if traci.simulation.getTime() % 360 == 0:

        for edge in edges:

            if edge.getID() in tazlist:

                traci.edge.setEffort(edge.getID(), traci.edge.getTraveltime(edge.getID()) + 30)

            else:

                traci.edge.setEffort(edge.getID(), traci.edge.getTraveltime(edge.getID()))

        for vehId in traci.simulation.getDepartedIDList():

            traci.vehicle.rerouteEffort(vehId)

    step += 1

I am not sure how the code written in <routing> in sumo.cfg is applied together with the rerouteEffort written in traci Python, and how to apply it through traci Python. I want the following codes to be applied.

weights.random-factor 

device.rerouting.period, 

device.rerouting.adaptation-steps, 

device.rerouting.adaptation-interval,

device.rerouting.with-taz,

device.rerouting.threads,

device.rerouting.synchronize,

You have reviewed my question, thank you very much. I hope you have a great day ahead.

Thank you.
