Dear Jakob,
Thank you in advance for the useful information. in the following, I want
to change the class of the vehicle added after copying the vType_1 , for
instance, to taxi. So, I used these methods as follows:
if step == 20:
traci.vehicle.add('vehicle_0','route_0','vType_0')
if step == 30:
traci.vehicletype.copy('vType_0','vType_1')
traci.vehicle.add('vehicle_1','route_0','vType_1')
traci.vehicletype.setVehicleClass('vType_1','taxi')
traci.vehicletype.setShapeClass('vType_1','passenger')
But the vehicle class of the vType_1 vehicle remains as same as the vehicle
class of the vType_0 vehicle when the simulation is run in GUI. I would be
thankful for any point in this case.
Regards,
Ali
