The highway video surveillance system mainly monitors toll stations, tunnels, service areas, etc. After more than 10 years of development, the monitoring technology system and equipment manufacturers selected in different periods are different for each road section, resulting in the monitoring system of each road section.

 Fully compatible and interoperable, unable to give full play to the functions of traffic monitoring of global path guidance, multi-path traffic flow control, networked dispatch, and timely and unified dispatch in response to emergencies. It is also unable to maximize expressway traffic capacity and build interconnectedness. The networked video surveillance system is imminent.
