Abstract: Aiming at solving the problems of low accuracy, low robustness to shadows and incapability of measuring multiple vehicle speed simultaneously in current methods, this paper introduces a new vehicle speed measurement method based on the model for vehicle speed measurement through video. A vehicle speed measurement system through video based on this model has achieved satisfactory results, and the error rate of the speed measurement is below 3 percent in some conditions
