The invention relates to a vehicle parameter identification method based on deceleration strip sound analysis. According to the invention, acoustic waveform is acquired by a senor in real time when a vehicle passes two deceleration strips, and the speed of the vehicle is acquired by using the wave crest time and the distance between the two deceleration strips; the wheelbase between two wheels of the vehicle is further acquired on the basis of acquiring the speed of the vehicle, and the acquired wheelbase is compared with basic vehicle type wheelbase information so as to deduce the type of the detected vehicle, thereby finishing vehicle classification. The vehicle parameter identification method only needs one sensor, thereby overcoming a defect of difficult synchronization in a multi-sensor detection environment. The method provided by the invention acquires the acoustic waveform of the deceleration strip easily, mainly completes vehicle speed measurement and vehicle type identification within a time domain, and is simpler and more accurate than other existing methods.
