Design of Traffic Accident Sensor Based On Binary Detector

According to the difficulty of highway traffic abnormal event detection and high cost,a design method of highway abnormal event sensor based on binary detector is proposed.By using the characteristic of binary detector, through the design of the SCM and the combination of state recognition algorithm to obtain the traffic flow, time share and other traffic status parameters. In order to reduce the design difficulty of the abnormal event detection algorithm of the control center and improve the operating efficiency of the overall system, the sensor selectively provides the necessary traffic status parameters. Finally, the control center analyzes the traffic state parameters Processing, enabling abnormal events detection; simulation results show that the design is feasible.
