At present, video surveillance and toll collection systems of traditional electromechanical systems have been operating stably for many years in expressway operation management, but their functions are relatively unitary and the phenomenon of information islanding is relatively serious. In order to resolve this problem, focuses on how the intelligent management and control system of the expressway seamlessly connects with the dedicated short-range communication (DSRC) road traffic flow outside the system, traffic flow monitoring data of the whole section, meteorological state monitoring data and video detection data of traffic events. At the same time, information services at the road network level are taken into account to achieve data sharing and exchange with the Ministry of Transport, the road network center of the provincial department of transport, the surrounding expressway network, local road management departments, meteorological departments, etc. It provides data support for expressway operation monitoring, early-warning, auxiliary decision-making, emergency management, information release and other functions.
