Re: [sumo-user] Keeping track of vehicles entering and exiting an edge

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

the proposed method would mostly work except for edges that are very short (vehicles might pass that edge in a single simulation step without showing up in getLastStepVehicleIDs).

If you do not need the data while the simulation is running you could post-process the vehicle route output in FILE using options

--vehroute-output FILE --vehroute-output.exit-times

This gives you the time each vehicle exited for each edge in the route.

regards,

Jakob

Hello

Is there an efficient way to keep track of vehicles entering and exiting an edge. I'd like to keep track of the vehicle ID, when they enter an edge and when they exit for the entire network.

My first thought is to use Traci to get edge.getLastStepVehicleIDs() for consecutive time steps. Convert them to sets and take the difference between them. 

Thanks
