Re: [sumo-user] Traci + Sumo : Drive vehicle based on edge weight from Source to Destination
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.
