The invention includes steps: (1) establishing corresponding table between number of road junction and name of road section; (2) discriminating and processing error data; (3) obtaining average speed of road section. Average time of travel on road section is equal to sum of average running time and average waiting time. Running length of vehicle is equal to length of road section minus length of vehicle queue at road section under average meaning. Roads are divided into rapid road, main road, secondary road, and branch road. Detecting speed on the spot obtains anticipant speed on different grades of road. Average running time is obtained from average running length of vehicle divided by anticipant speed on different grades of road. Based on M / M / 1 theory in queuing theory, the disclosed method obtains average waiting time. Based on length of road, average running time and average waiting time, the method obtains average speed on road. Features are: easy, quick and high reliability.
