"Tenth" Shanghai ITS Planning and Implementation 2003-2-24 China Third Party Logistics Network
I. Shanghai ITS research, problems and gaps in the application process
1. Road network infrastructure is not perfect
ITS can play a lot of role in practical applications, to a large extent, depending on the construction of urban infrastructure. Although ITS can monitor and dispatch vehicles, improve the efficiency of transportation systems, but unable to solve the deep contradiction between limited road resources and huge, rapidly growing travel needs. ITS needs to further improve system operation efficiency on the basis of perfect urban transport infrastructure, solve traffic congestion, safety and environmental issues. At present, Shanghai's overall road network system is still not developed, has not formed a modern, stereo modern traffic network.
2. Fund issues
Realize the intelligent scheduling of the entire urban transportation system or bus and taxi, realize intelligent traffic management of each road, each vehicle needs to be equipped with information receiving system, and each road must be installed and monitoring system, you need to invest huge funds. At present, our economic strength has a large gap between the developed countries in Western countries. It is impossible to invest huge funds in the United States, Europe and Japan to carry out the comprehensive research and development of ITS, which can only be based on our ability to select the target. ITS research and application in the project.
3, institutional problem
In the field of urban transportation, due to the self-contained system of various professional transportation systems, the inter-information cannot be shared, and it hinders the full play of each sub-system benefit, and the integrated ITS is difficult to build and operate. For example, the intelligent traffic management system established by the Public Security Traffic Management Department. However, in real time monitoring road traffic, but because the bus and rental schedule system does not connect, the effective information of the public transportation system is lacking, and its system monitoring and traffic information release. vice versa. Therefore, how to organize, coordinate the competent authorities and various professional transportation systems to promote ITS research and application, become the key to the "10th Five-Year" ITS planning and application.
4. Quality issues of traffic participants
Every traffic participant's behavior affects the operational efficiency of the entire transportation system. For example, pedestrians are not bad, and the awareness of road power is not allowed. The pedestrians are in crossing the road, the streets and the underground passages are not going, and they should find shortcuts in the traffic. They will be able to limit ITS better. Play a role.
5. ITS unified planning framework and construction operation standard problem
ITS unified planning framework and construction operation standards are the premise and foundation of ITS coordinated development, related hardware equipment and software products form a huge industry. Currently, Shanghai is actively studying to develop their own ITS architecture frameworks and standards.
6, Shanghai still has a large gap compared with foreign countries in ITS technology, equipment, talent and capital investment
At present, Shanghai has mainly tracked foreign advanced technology in ITS research and development, and combined with my country's national conditions for digestion, although there is a certain foundation, the capital investment and research power is still insufficient, and the industrialization is still to start.
