Abstract:Traffic violations and the traffic conflict discrimination difficulties at present this problem, according to the characteristics of the doppler effect is applied to the real-time road traffic conflict discrimination in the process of building system, realize the vehicle running status and operation parameters of real-time display, we design a light Banks display, implement automatic discriminant for traffic violations, traffic accident, the hd camera targeted forensics and linkage. Select the west coast of Qingdao economic district Jiang Shanna road and river road intersection validated peccancy vehicles and traffic accident analysis and using the Vissim simulation equivalent simulation display doppler radar detection system of traffic condition, to verify the effectiveness of the technology, for the intellectualized control platform of urban road construction, traffic running situation forecast, traffic conflict discriminant provides real-time and reliable information support.
