Dear Joseph,
in the case of two vehicles following each other on the same lane, you can
use the TraCI function traci.vehicle.getLeader
<https://sumo.dlr.de/pydoc/traci._vehicle.html#VehicleDomain-getLeader> .
It will search downstream of the current vehicle whether it can find a
leader within a given distance (100m by default). If you want to know the
distance between random vehicles, you can get their positions using other
Traci functions like traci.vehicle.getPosition
<https://sumo.dlr.de/pydoc/traci._vehicle.html#VehicleDomain-getPosition>
, traci.vehicle.getLanePosition
<https://sumo.dlr.de/pydoc/traci._vehicle.html#VehicleDomain-getLanePosition>
, traci.vehicle.getLaneID
<https://sumo.dlr.de/pydoc/traci._vehicle.html#VehicleDomain-getLaneID> .
Then you can use them as input of a distance metric (euclidean distance,
routing in the road graph using sumolib.net.getShortestPath
<https://sumo.dlr.de/pydoc/sumolib.net.html> ,...).
Best regards
Mirko

Hi,
I need to find a way to get the distance between any two vehicles in the
simulation. Is there a TraCI function that can do so?
Thanks,
Joseph Grech
