Intelligent transformation of traffic intersection

With the increasing urbanization rate of the population and the popularity of cars, the pressure on urban transportation is increasing.In order to realize smart city, intelligent transportation, intelligent transformation of traffic intersections is the most important node in the whole urban traffic system.Real-time perception and effective communication of traffic intersection information can effectively carry out intelligent management of road traffic flow, reduce congestion, ensure traffic safety, and improve the quality of life of residents.

The traffic intersection is an outdoor environment, and all kinds of bad weather are possible, such as frost and snow, high temperature and heat, heavy rain, typhoon, dust storm and so on.In this harsh environment, stable and reliable real-time signal transmission is required, and wireless communication cannot meet the requirements.The most ideal transmission mode is wired, such as network cable or optical fiber. With the implementation of national and local smart cities, intelligent transportation and other strategies, the newly built roads have basically laid optical fibers, and the intersection wired network has been covered.

Due to historical reasons, the earlier built traffic junctions have backward facilities. Because no signal cable is laid and no pipeline wiring is reserved, communication is a primary problem for intelligent transformation.If the network is re-laid, it is necessary to cut the road ground slot wiring, or drilling and eyeballing and threading, requiring professional equipment and construction personnel, huge project, high requirements, long cycle, low efficiency and high cost.
