Hi Jane, The text refers to the length of the vehicle and its speed. It explains the errors that can be made if you try to aggregate the outputs of the simulation spatially.

" https://sumo.dlr.de/docs/Simulation/Output/Lane-_or_Edge-based_Traffic_Measures.html#how_to_aggregate_derive_further_values How to define vehicles that are long and slow? Does it mean the type of vehicle or the route of vehicels? Best regards, Jane
