The highway monitoring system is an important means of adjusting the highway system to achieve safe, efficient, energy-saving, and environmentally friendly operation. The function of the highway monitoring system is to achieve real-time monitoring and traffic control of the highway network. Under the existing road and environmental conditions, by analyzing, processing, and predicting the collected information in real time, effective traffic control measures can be taken to prevent possible traffic incidents, accidents, and blockages; When sudden traffic accidents or changes in road environment cause traffic congestion, the system should promptly detect and take effective measures to alleviate and eliminate them, in order to prevent greater impact on road network traffic and improve the efficiency and safety of road network operation.
The highway monitoring system is generally divided into two parts according to its functions: toll monitoring system and road monitoring system. The toll monitoring system mainly observes and records the toll situation of the toll station's lanes, toll plaza, and toll booth, the types of vehicles passing through the toll lane, the operation process of toll collectors, as well as unexpected and special events during the toll process, and implements effective supervision. The road monitoring system is mainly used to monitor key sections of highways such as highways, interchanges, tunnels, etc., to grasp the traffic conditions of highways, timely detect traffic congestion and illegal vehicles, provide timely guidance, and ensure the safety and smoothness of highways.
