In urban area, traffic light is a contrived obstacle, in the same traffic state, traffic lights will affect the travel time and therefore can not rely on the travel time to determine the traffic conditions. This paper to drive through the actual record in Taipei collected GPS location and time information to be converted to temporal mean speed and spatial mean speed.
