  • Thread-topic: Libsumo usage with taxi vehicles
Dear all!

I tried to use libsumo instead of traci for new taxi routing algorithm to reduce overheads. 

The algorithm which worked for traci now crashes with libsumo.libsumo.FatalTraCIError: bad allocation error, when I use vehicle.getParameter() function e.g. like that: 

vehicle.getParameter(taxi, "device.taxi.currentCustomers")

  1. Is it the case mentioned in the documentation (so this function, indeed, should not work for libsumo):

The following things currently do not work (or work differently than with the TraCI Python client): subscriptions that require additional arguments (except for vehicle.getLeader)?

  1. More general question would be, then, should I consider using libsumo for taxi vehicles if I need to obtain information about reservations, taxi fleet, current routes etc from SUMO or it would be better to stay with traci? I am currently creating Gym environment for applying RL for ride-pooling problem, and already feel that the performance will be really an issue.
Thank you in advance,
Klavdiia Bochenina
