System and method for monitoring vehicles to pass through intersections

The invention provides a system and method for monitoring vehicles to pass through intersections. The system comprises a client and a cloud server, the client receives the differential data to calculate the high-precision position information, fuses the sensor data to correct the high-precision position information and uploads the corrected high-precision position information and the vehicle information to the cloud server, and the cloud server dynamically divides electronic fences for the intersections, collects the corrected high-precision position information and vehicle information, combines with a high-precision map to judge whether the vehicle enters the electronic fences or not, judges whether the behaviors of the vehicles entering the electronic fences are abnormal or not, generates the warning information for the vehicles with the abnormal behaviors, and sends the warning information to the client for storage. The system and the method have the real-time interaction capability, and can cultivate good
