[sumo-user] Adding a new vehicle

[謝昀宸 <sdfg014025xx@xxxxxxxxx>]

Hello,

I want to add vehicles randomly in the simulation. 

I try traci.route.add and then traci.vehicle.add

But when I run the simulation, an error message appears as follows:

traci.exceptions.TraCIException: Invalid route 'i_r1' for vehicle 'i_v1'

I have confirmed that the route is error-free because even if there is only one edge left on the route, there is still this problem

What can I solve?

Many thanks,

Yu Wang
