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

[Shekar V <gv....@gm...>]

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
