The expressway is a fully enclosed and all-overpass road. Its ideal characteristics are safety, speed, efficiency, comfort and convenience. With the rapid development of my country's national economy, the number of motor vehicles has increased rapidly, and the traffic demand on expressways is also increasing. At the same time, traffic congestion, traffic accidents, traffic violations, road pollution and other behavior events frequently occur, causing huge traffic safety hazards to the operation of road vehicles, making highway pavement monitoring become the focus of traffic facility construction and management departments.
The highway monitoring system is an important part of the highway and an important means to ensure the high-speed and safe operation of traffic. Its hardware equipment includes control facilities, monitoring facilities, intelligence facilities, transmission facilities, display facilities, and control centers. The working method is that the traffic information obtained by the monitoring and intelligence facilities is transmitted to the control center through the transmission facility, and the analysis and processing results of the control center are transmitted from the transmission facility to the control facility and display facility to control the traffic.
The HRUI highway monitoring system mainly uses industrial Ethernet technology to connect high-definition network cameras, various sensors buried on the road, variable information boards and other front-end equipment. By collecting traffic flow, operating conditions, environmental weather and other data, the high-speed Real-time information on the road surface is communicated to the road supervision department in time. After the information is processed by the preset traffic control strategy plan, it is then provided to the drivers through the information board and other methods to realize the monitoring of the key sections of the expressway, grasp the expressway traffic conditions, find the problems in time, give prompt guidance, and ensure The highway is safe and smooth.
