Abstract In order to manage the traffic well and eliminate traffic safety hidden troubles in traffic safety,the way of detecting speed with radar (Doppler effect) is usually adopted to identify and sample speed of illegally running automobile (too fast or too slow). However,another wireless receiving equipment,called electric dog,appears in the recent market. Installed in the automobile,the system can help capture the radar speed detecting signal and an alarm signal will be produced when the automobile approaches the radar detection areas,then the automobile will turn to normal run and escape the traffic management. Once the automobile has passed the radar detection areas,it can run illegally again and the danger still exists. To prevent this circumstance,a new speed identification system with infrared sensor has been developed. It can not only identity the speed,but also show how much it exceeds (+ΔV) or lags (-ΔV) the speed limits. According to the information,it can drive the sampling system to work (to print or take pictures). This way the traffic management can be strengthened effectively,minimizing hidden accidents.
