Re: [sumo-user] Traci + Sumo : Drive vehicle based on edge weight from Source to Destination
The function setRoute requires that the list of edges starts with the current vehicle edge.
This means, once the vehicle has reached ed05 it is no longer valid to set the route

Dear Sir,

Successfully implemented following code : 

 """execute the TraCI control loop"""
    step = 0
    while traci.simulation.getMinExpectedNumber() > 0:
        traci.simulationStep()
        print("Vehicle List")
        my_vehicle_list = traci.vehicle.getIDList()
        print(my_vehicle_list)

        for vehicle_id in my_vehicle_list:
                traci.vehicle.setRoute(vehicle_id, ['ed04','ed05','ed06','ed07','ed08','ed10','ed03'])
                print (vehicle_id)
        step += 1
    traci.close()
    sys.stdout.flush()

But When I am executing following line :
                traci.vehicle.setRoute(vehicle_id, ['ed04','ed05','ed06','ed07','ed08','ed10','ed03'])

I got Error : 
traci.exceptions.TraCIException: Route replacement failed for veh1
 

My Route File is :
<routes>
    <vType accel="1.0" decel="5.0" id="Car" length="2.0" maxSpeed="100.0" sigma="0.0" />
    <route id="route0" edges="ed01 ed02 ed03 ed04 ed05 ed06 ed07 ed01"/>
    <route id="route1" edges="ed04 ed05 ed06 ed07 ed08 ed10 ed03 ed04"/>
    <vehicle depart="0" id="veh1" route="route1" type="Car" />
</routes>

Sorry sir for asking such a silly questions,But I am new to this.

your script starts with the lines:

while traci.simulation.getMinExpectedNumber() > 0:
        traci.simulationStep()

This loop runs the simulation until all vehicles are gone. Your whole code comes afterwards.
Instead put your traci code inside the loop.

Thanks sir for your reply.

I am attaching my Traci_runner.py file.

Sir, I am trying your suggestion. But I am not able to get why my_vehicle_list Prints Blank --> () ??

   my_vehicle_list = traci.vehicle.getIDList()
    print(my_vehicle_list) // Why this Prints Blank --> () ??

    for vehicle_id in my_vehicle_list:
        traci.vehicle.setRoute(vehicle_id, ['ed04','ed05','ed06','ed07','ed08','ed10','ed03','ed04'])
        print (vehicle_id)
        step += 1

Thanks for reply sir.

But what about following?

How to drive vehicle based on Edge weight given Source & destination Junction using Traci?

You can set custom edge weights either for individual vehicles or for all vehicles at the same time. See:

Dear Listing,

I have implemented code for Traci to Start SUMO. [Attached Here With]
My target is to drive car using Ant colony algorithm from given Source to destination Junction.
But for now I want help to drive vehicle based on Edge weight.

So my Question is :

1. How to give weight to the edge using Traci Code?
2. How to drive vehicle based on Edge weight given Source & destination Junction?

Please advise me to resolve my query.

:)

Thanks & Best Regards.
