Intelligent Transportation System Structure and Development Status

Judging from the hierarchical structure of the system structure, theintelligent transportation system主要由感官控制层、big data sharing service platform layer and an application platform layer (including: management and control platforms/intelligent management platforms for intelligent management departments, and transportation to the public The composition of the information service set should also consider the system operation and maintenance management platform that ensures the continuous healthy operation of the entire system. At present, the perception of the control layer and the single-domain application system layer are relatively well-developed in the traditional traffic management model. In addition, the traffic information service under the collision of technology and capital, innovation model, rapid development and obtain a certain scale of application. Big data sharing service platform, research and decision platform and system operation and maintenance management platform are still in the stage of exploration, practice and seeking ground.

In traditional intelligent traffic systems, key equipment includes traffic flow detection, signal control, video surveillance, induced release, event detection, bayonet and electric police. In comparison, traffic flow detection, traffic signal control, video surveillance, bayonet, and electric police are almost standard products for project construction, and traffic-induced release and traffic incident detection are niche products with a limited share. Traffic video surveillance is well-known domestic enterprises such as Hikvision, Dahua, Yushu, Dongfang.com, Zhongxingwei, and Tianweiye. In the geomagnetic field of traffic flow detection, Beijing Marui Data, Wuxi Sensing Technology, Tianjin Shuntong, and U.S. Sishen accounted for more than 80% of the geomagnetism market; while signal control manufacturers had about 150 domestic companies, including Hisense, Rice, Huatong. Tongxiang and Jerry, etc. accounted for relatively high; the threshold for competition in the electric police bayonet is relatively low, but in the past two years, major enterprises such as Hikvision, Dahua, Yushi have monopolized advantages.

As the Internet of Things, RFID technology, standards and regulations, and automotive license plate applications become more and more mature, the concept of thorough perception will gradually be integrated into intelligent transportation system equipment. The integration of traditional sensing devices and new technologies, application system upgrades, or will set off a new round of construction boom, product technology innovation will also bring new opportunities for corporate competition.
