Hello, the method takes the average speed of all vehicles on an edge at the specified second and computes the travel time from that. This estimation may be subject to strong fluctuations, especially near a traffic light. In addition there is more than one possible way for weighing speed differences among the lanes. To be on the safe side you could track the average speed for the individual lanes and do some averaging (over time) yourself. regards, Jakob
