Hi Robbin,
Thanks for your answer. However, specifying the lane with its string identifier
is not working for me. Did you actually insert a vehicle in an edge other than
the first one of the route?
The following call works, inserting the vehicle on lane 1 (2nd one) of the
first edge in the route:
traci.vehicle.add('block', routes[0], depart=0, pos=20, speed=0,lane=1)
However, if I specify the lane with a string, so that I can insert it to an
edge other than the first one, with:
traci.vehicle.add('block', routes[0], depart=0, pos=20, speed=0,lane='AtoB_1')
I get the following error:
Traceback (most recent call last):
[omitted]
File "c:\XXXXXX\sumo-0.23.0\tools\traci\vehicle.py", line 874, in add
traci._message.string += struct.pack("!BB", tc.TYPE_BYTE, lane)
struct.error: cannot convert argument to integer
Looking into traci\vehicle.py in the add method, there is:
traci._message.string += struct.pack("!BB", tc.TYPE_BYTE, lane)
so it seems that it is actually expecting "lane" to be an integer (i.e.
TYPE_BYTE) and not a TYPE_STRING.
If tried to use addFull, since the parameters are string:
traci.vehicle.addFull('block', routes[0], departPos="20",
departSpeed="0",departLane='AtoB_1')
but then I get the following error regarding the "departLane":
traci.TraCIException: Invalid departLane definition for vehicle 'block';
must be one of ("random", "free", "allowed", "best", "first", or an int>=0)
Any way around it?
Thanks

Hi Didac,
I recently used this Traci command. The whole command specification includes a
position and laneID as well, so you can just specify which lane you want the
vehicle to start (a lane is even more precise than an edge, when an edge has
multiple lanes). The route is needed by SUMO so it knows where the vehicle has
to go after it leaves the lane where you injected it.

Subject: [sumo-user] Adding a vehicle at a given edge/lane/position
Hi,
I'd like to add a vehicle (to simulate a lane block) to a given position of a
given lane of a given edge.
I've seen that TraCI has the vehicle.add(...) method, but it only mentions
routeID, not edgeID.
How can I do so?
Thanks,
Didac
