Several works that should be paid attention to in the development of "intelligent transportation management system"

Abstract: in view of the current popular development trend of "intelligent transportation system (ITS)", this paper combines the specific application in practical work, and draws lessons from the advanced experience of developing "intelligent transportation management" system at home and abroad, This paper puts forward several works that should be paid attention to by monitoring the separation of fixtures or detecting the distance between two fixed points on the sample through sensors, for everyone to discuss

I. preface

since the 1990s, with the rapid and healthy development of China's national economy, the construction of urban road infrastructure has been increasingly improved, the number of motor vehicles has been increasing, the number of road traffic accidents and deaths has increased, the driving order of vehicles and the urban environment have shown a deteriorating trend, and the contradiction between road supply and traffic demand is still very prominent. In order to solve the problem of traffic congestion, although the road traffic department has vigorously increased investment in science and technology, made efforts to improve road traffic facilities, and actively explored methods and strategies to improve urban road traffic conditions, there is still a big gap from the goal of "asking for police force and combat effectiveness from science and technology". What measures should be taken to maximize the role of the existing system? How to combine the construction of "intelligent transportation system (ITS)" and expand the traffic management and command system has become a practical focus that we must face and urgently need to solve

II. Basic overview of the development of domestic intelligent transportation management system

"intelligent transportation" formed a systematic concept, which originated in the 1980s (many experts and scholars have elaborated on the specific content of its, and this article will not describe it). At present, in addition to the vigorous development of intelligent transportation systems in Europe, the United States, Japan and other countries, emerging industrial and developing countries are also beginning to carry out the comprehensive development and research of its. China began to use electronic information technology in transportation and management in the late 1970s and early 1980s, and took the lead in gradually building traffic command and control centers in Beijing, Shanghai, Nanjing, Guangzhou and other cities, and establishing traffic signal control and traffic monitoring systems. In order to further develop and apply intelligent transportation system, the "national intelligent transportation system engineering technology research center" was approved by the Ministry of science and technology in November 1999. From the perspective of coordination and organization, the Ministry of science and technology took the lead in organizing staff to remember the correct wiring method. The Ministry of communications, the Ministry of public security, the Ministry of construction, the Ministry of railways, the State Bureau of technical supervision and other relevant departments jointly prepared to establish the "China its government coordination group", Overall responsible for the formulation of China's its strategy, the formulation of standards, the organization of talent training and the research and demonstration of its key technologies. In 2001, Guangzhou was included in one of the four "s demonstration cities where it must pay full attention to these issues". In 2002, the number of demonstration cities expanded to ten

in the 1980s, the Guangzhou road traffic management department started the application of electronic information technology for traffic facilities and traffic signal control, developed the regional signal control system by itself, and gradually established some computer information management application systems. In 1992, Guangzhou built a traffic command and control center, introduced the Australian scats regional signal control system, and built a closed-circuit television monitoring system and electronic map. In the next decade, it not only expanded the control scope of the regional signal control system and closed-circuit television monitoring system, but also built 122 alarm receiving and handling systems, large screen display, traffic flow detection, variable information board, traffic violation shooting and other subsystems in batches, Electronic information technology and communication technology have been applied to accident handling, traffic violations, vehicle driver management, traffic administration and other work, which has achieved good social benefits and achieved a qualitative leap in road traffic management means

however, with the continuous growth of motor vehicles and population travel, the contradiction between road supply and traffic demand is still very acute. The existing service management mode and traffic management scientific and technological means can no longer adapt to the road traffic management work under the new situation. Therefore, Guangzhou road traffic management department keeps pace with the times, develops and innovates, We began to carefully analyze and study the development technology and experience of intelligent traffic management system at home and abroad, and put forward the idea of building "Guangzhou intelligent traffic management command system" in combination with our own work practice

III. several tasks that should be paid attention to in the development of "intelligent traffic management system"

in order to adapt to the development of road traffic management under the new situation, constantly absorb advanced technology and management experience, and fully apply it to practical work, it is very necessary to build an intelligent traffic management system. However, China is still a developing country, and the economic development of various regions is different, The characteristics and status of road traffic display are also different, so we can't rush forward. We should "analyze specific problems", and cities with conditions can play a leading role. Even if some cities build "intelligent traffic management system" first, we should pay attention to combining the characteristics of urban road traffic, carefully tap the potential of the existing system, do a good job in technical selection and economic analysis, and avoid the waste of funds and unreasonable technical framework. Therefore, the author believes that the development of "intelligent traffic management system" should pay attention to the following work:

(I) determine the city's traffic development strategy, seriously formulate the urban traffic planning and road traffic management planning

(II) formulate and improve road traffic regulations and standardize administrative procedures and means

China's existing road traffic regulations system is basically complete, but it is not very perfect. With the development of social economy, there will be many new problems and new things. Therefore, it is necessary to
