Determination of the Vehicles Speed Using Acoustic Vector Sensor

Abstract

The method for determining the speed of vehicles using acoustic vector sensor and sound intensity measurement technique was presented in the paper. First, the theoretical basis of the proposed method was explained. Next, the details of the developed algorithm of sound intensity processing both in time domain and in frequency domain were described. Optimization process of the method was also presented. Finally, the proposed measurement method was tested in real conditions. The obtained results confirm that the proposed method may complement the currently used vehicle speed measurement techniques.
