Hello,
I am trying to make some simple applications using TraCI.
*usingtraci1.py*
This code executes correctly and vehicle with vehicle ID v1 is stops
whenever the traffic light is red irrespective of it's position.
traci.simulationStep()
if traci.trafficlights.getPhase("B2") == 0: #signal at B2 in state
GGrr
traci.vehicle.setSpeed("v1", 0)
else:
traci.vehicle.setSpeed("v1", 20)
step = step + 1
But the problem once the vehicle v1 leaves the network the execution stops
and an error is generated because v1 is no longer in network. Please help
understand how may I avoid it.
*My approach to avoid this error*:
I thought of capturing vehicle ID and writing that to txt file. I'll
re-structure the if statement and only if v1 is in the network then the
previous command will be executed.
However I am getting an in file *usingtraci3.py*
*Error: tcpip::Socket::recvAndCheck @ recv: Socket reset by peer*
*Quitting (on error).*
I think it's for the wrong usage of command:
get_id = traci.vehicle.getId()
Please help me identify the correct command.
Next, I plan write all the values to text file:
with open ("vid.txt", "w") as vehicle_id:
get_id = traci.vehicle.getLastStepVehicleIDs()
vehicle_id.write (str(get_id) + '\n')
Is there a standard syntax for using commands retrieving vehicle ID?
How can we use these values in run time?
For eg:
if (traci.vehicle.getId() == 'A1')
traci.trafficlights.setPhase("traffic_light_index", phase_index)
Thank you.
