Highway monitoring system is an important means to adjust the highway system to achieve safe, efficient, energy saving and environmental protection operation. The function of expressway monitoring system is to realize real-time monitoring and traffic control of expressway network. Under the existing road and environmental conditions, through real-time analysis, processing and prediction of the collected information, effective traffic control means are adopted to prevent possible traffic incidents, accidents and jams; In case of traffic jam caused by sudden traffic accident or road environment change, the system should find out in time and take effective measures to alleviate and eliminate, so as to prevent greater impact on road network traffic and improve the utilization efficiency and safety of road network operation.
Expressway monitoring system is generally divided into toll monitoring system and road monitoring system according to the function. The toll monitoring system is mainly to observe and record the toll situation of the lane, toll plaza and toll booth of toll station, the type of vehicles passing through the toll lane, the operation process of toll collector, and the emergency and special events in the process of toll collection, so as to implement effective supervision.
