Re: [sumo-user] How to use the getLeader in python to retrieve the leade

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

with traci, either check whether the vehicle '00' has departed yet or catch the TraCIException (it's harmless).

for logging, see https://github.com/eclipse/sumo/issues/7864

I want to use traCI to get the distance of the car in front and log it, how
can I do it? please help

I started with trying the following in python script but this gave me error
that the vehID is not known, that in my case is 00

 tl = traci.vehicle.getLeader("00", "200")


Also how can I log the getLeader parameter at each time step of simulation?

I have also attached the code getLeader_python_code_example.txt

Thanks in advance,
