| Abstract: | Based on the model of incident in VISSIM software,we simulated an incident that caused by a car suddenly stop on it,and then collect the traffic parameters before and after the incident.After obtaining the original simulated data,we use DB2 wavelet analysis to deal and process the traffic parameters,and then propose the results based on BP neural network.After the simulation of MATLAB language,the results shows that this new method has many advantages and has a such higher detection rate,lower false alarm rate and shorter mean detection time. |
