Hello all,
I have a problem with using traci vehicle subscription filters in python. I
am subscribing to the host car and using a Lane filter to filter out the
traffic objects in specific lanes. Basically I want to filter out all other
vehicles except for the ones in host car's lane and its left and right
neighboring lanes. I used the following code for this purpose:
traci.vehicle.subscribeContext('10001',tc.CMD_GET_VEHICLE_VARIABLE,0.0,[tc.VAR_POSITION3D,
tc.VAR_SPEED,tc.VAR_ANGLE])
traci.vehicle.addSubscriptionFilterLanes([-1,0,1], noOpposite=False,
downstreamDist=200.0,
upstreamDist=20.0)
As per the documentation, 0 and -1 are the lane indices of the Ego car and
its right neighboring lane. As for the left neighboring lane I used '1' as
Lane index. This is where the problem is occurring. I am getting the
subscription results of the traffic objects in Ego car and its right
neighboring lane, but not from the left neighboring lane. The attached
image shows one such situation where the subscription results of the car in
the opposite lane is also getting filtered out by the Lane filter.
How do I get the subscription result of the traffic object on the opposite
lane (left neighboring lane) as well?
Thank you and regards,
Shreevatsa
