Nanjing accelerates the creation of a smart city

Recently, the first phase of the Nanjing Smart Public Transportation System was officially launched. A total of one bid section is set up for the project. The bid section number is A1 bid section. The work includes: software development (including total system integration), decoration project (including integrated wiring), procurement of terminal equipment related to pilot projects, and “Qingao” passenger transportation guarantee. Regional coordination and dispatch center network equipment procurement, supporting multimedia equipment procurement, office and living furniture procurement. Software development includes: government command decision system software development, enterprise production management system software development, public travel service system (part of business) software development and third-party software procurement.

The total investment of the Nanjing Intelligent Public Transportation System is about 150 million yuan, of which the first phase investment is 83.50 million yuan and it is planned to be completed by the end of June next year. The entire system will consist of data center, government emergency command supervision and decision system, enterprise safety production operation dispatch system, intelligent public platform and other application systems. This system will support 35,000 vehicle dispatch terminals, 35,000 vehicle electronic monitoring terminals, and 1,000 Electronic stop signs, 200 sets of stations and 500 half-way electronic monitoring terminals, and millions of citizens inquiries online through multiple channels.

Traffic safety, traffic congestion and environmental pollution are three major problems that plague today's international transportation sector, with the most serious problems being traffic safety. With the use of intelligent transportation technology to improve the level of road management, the number of deaths per year in traffic accidents can be reduced by more than 30%, and the use efficiency of transportation can be improved by more than 50%. For this reason, various developed countries in the world have invested large amounts of funds and manpower to carry out large-scale intelligent traffic technology research experiments. At present, many developed countries have moved from the research and testing of the system to the overall deployment stage. The intelligent transportation system will be the mainstream of transportation development in the 21st century. This system can increase the existing road usage by 15% to 30%.

With the continuous development of sensor technology, communication technology, GIS technology (geographic information system), 3S technology (remote sensing technology, geographic information system, global positioning system technology) and computer technology, the collection of traffic information has gone from manual acquisition to The historical development process of traffic information collection from a single magnetic detector traffic information collection to multiple collections of multiple sources, and at the same time the gradual deepening of traffic information processing research at home and abroad, statistical analysis technology, artificial intelligence technology, data fusion technology, Parallel computing technology has gradually been applied to the processing of traffic information, making the processing of traffic information continuous development and innovation, and more satisfying the needs of ITS subsystem administrators and users.
