Overview of the highway industry
In recent years, remarkable achievements were made in highway construction in our country, the highway as the skeleton, the provincial trunk highway basic form as the main body of the national trunk road
network. The highway monitoring system has also made great progress as the core of the highway system. As a kind of visual management, highway monitoring system provides operation management with
real-time, accurate, complete traffic and traffic information. In the case of abnormal traffic, through the system can timely find the accident or blocked area, real time linkage release corresponding induction and
rescue information, avoid secondary accident, ensure the highway traffic efficiency and traffic safety.
Existing problems HD intelligent level highway monitoring system, and information collection cover is not complete, each subsystem information island, low degree of networking, regional coordination ability is
insufficient, public travel service level is not high. These problems severely restricted the highway informationization level of ascension, restricts the high speed highway network operation monitoring and
scientific management ability, also affects the highway emergency disposal ability and the ability of public service.
Along with the rapid development of security technology, how to utilize the existing advanced technology, enhance the level of highway network operation monitoring and scientific management, improve national
trunk highway network security performance and service quality, improve the highway emergency disposal ability and the ability of public service, to achieve national trunk highway network "visible, measurable
and controllable" development goals, and promoted the people safety, smooth, convenient and green road travel services has become a new generation of expressway monitoring system of the construction of the
