Hi Menno, This is what the mannaul says: *getLastStepMeanSpeed(self, detID)*
*getLastStepMeanSpeed(string) -> double Returns the current mean speed in m/s of vehicles that were on the named e2*. I am looking for a tool by which I can extract the flow characteristics at the time the vehicle is on the detector. So, is there any option to get more data of vehicles in traci.lanearea module?
