The occupancy here is defined as the ratio of the sum of vehicle lengths on the edge divided by the edge length (sum of the lengths of all lanes). Vehicles which are partly on the edge count only with the part which is on it. > BTW, is there any other traci function that can be used to measure if an edge > is congested? It depends on your definition of congestion. We usually use average speed or occupancy.
