Abstract

The existing automatic detection and recognition methods of traffic incidents were analyzed, a recognition method with vehicle acoustic signals was proposed based on wavelet decomposition(WD) and support vector machine(SVM). Vehicle acoustic signals were decomposed with WD, the powers in different frequencies were regarded as different incident eigenvectors, and the traffic incident classifier composed of multiple SVMs was trained. The acoustic signals of normal driving, braking and crash incidents were recognized. Test result shows that various traffic incidents can be recognized with vehicle acoustic signals, the recognition rate reaches 95%, so the proposed method is feasible.
