I. Urban intelligent traffic construction will turn to system sharing and information mining. Yang Jincai, President of Shenzhen Intelligent Transportation Industry Association: The China Urban Intelligent Transportation Forum has been held for five sessions. We discussed different topics in the five forums. It reflects the development process of urban intelligent transportation in China. Before the Shenzhen Universiade, we held the 6th China Urban Intelligent Transportation Forum to discuss the topic of “The Construction and Application of Integrated Transportation Information Systemâ€, which has a more positive significance.
Today, the infrastructure construction of large-scale urban traffic information systems in our country has taken initial shape. The next step is to turn system infrastructure construction into system sharing and information mining and utilization. As a practical means of service function, traffic information system not only serves large-scale social activities, integrates information resources of various transportation means, but also highlights safety and emergency functions. It is an important development direction of urban intelligent transportation.
Second, the construction of intelligent transportation system will usher in a period of 30 years of development Opportunities Guo Wenlong, director of the National Development and Reform Commission’s Traffic Technology Development and Standards Research Center: At present, China’s traffic modernization has been found from the comparison of China’s per-capita travel times and travel distances with international standards. The level is relatively low and there is a 40-50 year gap with Western countries.
At present, China's main transport investment is: the central government accounts for 15%, local governments account for 45%, domestic firms account for 35%, and foreign banks account for 5%. By 2050, China plans to complete the modernization of transportation. Its main sign is that the infrastructure network has been fully completed. The technical level and composition have fully met the needs of transportation development, and the quantity and quality have been optimized. The highway transportation infrastructure network has a clear hierarchy, reasonable layout, optimized structure and complete functions. The major coastal ports have become important regional or international logistics centers. The advantages of inland shipping have been fully realized. A modern water transport system has been built with the same infrastructure, water and land transport, regional network, and rivers and seas. The focus of traffic construction has shifted to the safety, efficiency, and connectivity of the maintenance system. It has built an integrated transportation system that is characterized by rapid passenger transportation, logistic logistics, intelligent operations, and optimized safety and environment.
If we look at the demand for expressways from the perspective of increasing urbanization level, the national highway network layout scheme can be summarized as 7918, that is, 7 Beijing radio lines, 9 longitudinal routes, and 18 horizontal routes, with a total scale of approximately 85,000 kilometers. To achieve the strategic goal of “high-speed encryption in the east, network integration in the middle, and connectivity in the westâ€.
Therefore, as a means of management, the construction of intelligent transportation systems will have a period of development opportunities of more than 30 years with the construction of national highway networks.
3. The overall goal of intelligent transportation is to improve road network utilization and energy conservation and emission reduction. Wang Xiaojing, chief engineer of Highway Research Institute of the Ministry of Transport and director of the National Intelligent Transportation System Engineering and Technology Research Center: According to Beijing’s practical experience, the construction of intelligent transportation systems is mainly Including the following three aspects:
1. ETC (non-stop charging system) lane construction using ETC (non-stop charging system) can reduce carbon dioxide emissions by 48.9% compared with manual cash collection methods. Therefore, Beijing plans to implement the lanes using ETC charging methods in 2010. The proportion reaches 30%.
At present, China's inter-provincial and city-to-city electronic non-stop charges have been applied in more than 15 provinces and cities. The largest inter-provincial and city-networked toll collection system has exceeded the 10,000-kilometer coverage. The construction of the ETC system has provided tremendous opportunities for banks such as ETC payment cards such as Peony Express Card.
2. Construction of Traffic Information Service System Taking Beijing as an example, the urban traffic information system includes 22 subsystems including the four systems of information collection and support system, control system, command system and emergency management.
In the construction of traffic information service centers and roadside systems, in addition to information collection, processing, and release technologies and systems, as well as the provision of effective information services, it is even more important to establish a capital chain and value chain for the sustainable construction of intelligent transportation systems. . For example, vehicle navigation services, vehicle guidance systems, traffic broadcasting stations, real-time traffic information websites, and the like.
3. Strengthening road network operation supervision, emergency response and service The key to the construction of the future intelligent transportation system is to construct the national road network emergency management system architecture, including basic settings such as highway safety design and basic information and communication system platform. For the vast number of security system integrators and contractors, the opportunity for the construction of intelligent transportation systems is to participate in the construction of facilities monitoring and early warning subsystems, night vision enhancement subsystems, emergency command centers, and video management systems.
The use of information provided by the National Road Network Emergency Management System to provide value-added services to the public through websites, PDAs, ETCOBU, dedicated broadcasting, VMS, lane control, etc. will be a very large market. In the process of realizing the intelligent transportation system, the key is to build an intelligent infrastructure consisting of sensor networks, communication facilities, network supercomputers, and intelligent software, and build a ubiquitous information network system in accordance with the requirements of reliable and low-cost informatization. Make data-based and knowledge-based industries an important emerging pillar industry.
Fourth, to build Shenzhen as a smart transportation innovation city Shenzhen City Public Security Bureau Traffic Police Bureau Traffic Technology Division Lin Weiwang: At present, Shenzhen Intelligent Traffic Management Information Service System construction includes a platform and eight systems, "a platform" that traffic sharing information Platform, “The Eight Systems†includes traffic information collection system, traffic signal control system, trunk line traffic guidance system, parking lot traffic guidance system, traffic incident system, intelligent traffic violation management system, gridded vehicle identification integrated application system, closed-circuit television surveillance system.
At present, the application of Shenzhen Electronic Police has greatly improved the efficiency of traffic law enforcement. According to statistics, in 2008, 327,000 traffic violations were seized at the traffic scene, and 170 cases were seized per person, accounting for 11.3% of the total seizures. In the same period, 1,850 sets of electronic police equipment seized 2.589 million traffic violations. The average number of seized equipment was 1,399, accounting for 88.7% of the total. The work efficiency was 8.2 times that of manual enforcement, which was equivalent to a 7.9-fold increase in road police.
In order to speed up the construction of Shenzhen Intelligent Traffic Management Information System, in the next few years we will build more than 1,000 sets of coil detectors, 425 closed-circuit television systems, more than 210 digital high-definition camera surveillance points and radio stations, road patrols, road construction, and microwave inspections. system.
In the future, the direction of intelligent transportation development in Shenzhen includes traffic signal control systems, trunk line traffic guidance systems, parking lot guidance systems, command centers, etc. The goal is to comprehensively use traffic management information and comprehensively control traffic to meet people’s convenience. The requirements of comfort and safety should be changed from passive control to active guidance, so as to achieve the purpose of improving the comprehensive operational efficiency of the roads, alleviating traffic congestion, reducing traffic accidents and increasing travel speed.
The Shenzhen Transportation Police Detachment's experience in developing intelligent transportation systems includes the following aspects:
1. After 10 years of development, the electronic police system has undergone great changes in terms of equipment functions and construction scale. The main innovations include: (1) The function of the equipment has expanded from the initial capture of the red light to the capture of vehicles. Various illegal activities such as retrograde, speeding, compacting lines, driving without lanes, and refusing orders for large trucks have met the needs of traffic management. (2) With the application of various new technologies such as digital imaging, photoelectric detection, pressure detection, and wireless transmission to electronic eyes, the performance of electronic police is becoming increasingly powerful. (3) The installation method has evolved from the traditional vertical rod type to the cantilever type, broadening the horizon and scope of monitoring, and the high-speed continuous shooting and lane detection technology has improved the rigor and impartiality of illegal picture evidence.
2. The grid-based license plate recognition system has expanded new fields for traffic law enforcement by participating in the work of assisting in the investigation and punishment of traffic violations, assisting in investigation of cases, discovering fake set-type vehicles, analysis of traffic flow and travel habits, and road traffic management. Improve the efficiency of law enforcement.
3. The traffic command center uses the GPS device of the police vehicle to quickly locate the nearest police car at the point where the incident occurred, reasonably dispatches the police force, improves the ability to handle emergencies quickly, and reduces the degree of negative impact of the incident on the traffic.
4. The mainline traffic guidance system is gradually induced by the induced large screen placed on the main road to form a continuous induction to the vehicle, effectively improving the existing road usage rate, and achieving a balanced distribution of road network traffic.
We believe that comprehensive information collection methods and rich information content are prerequisites for providing sound information services. In the future, the direction of Shenzhen's intelligent transportation system construction is to use integrated control systems to realize rapid event processing and reduce information under the support of information. The impact of traffic time on road traffic; the application of all scientific and technological information technology to achieve a reasonable and rapid dispatch of the police force; through a variety of information collection methods, the application of sophisticated time detection algorithms to achieve rapid discovery events, so as to provide people with convenient And safe traffic.
V. Construction of parking transfer system to ease the traffic in the core area of ​​large-scale activities Zhu Hao, director of the Shanghai Urban Comprehensive Transportation Planning Institute and Intelligent Transportation Center: With the rapid growth of cars, the development of parking and transfer systems in the central area of ​​Shanghai is the solution to the central area. One of the ways out of parking difficulties is also an important transportation strategy that meets the needs of the city's scale expansion and layout adjustment, and it is also an important link for the integration of transportation in the Yangtze River Delta region. In addition, the public welfare of the parking and transfer system is reflected in the relief of road traffic congestion in the central area, which is an important part of the implementation of the “Public Transport Priority†traffic development strategy, regional differentiated traffic management policies, and implementation of energy conservation and emission reduction policies.
At present, we have divided the development of the Shanghai parking transfer system into three phases: (1) The lead-in period - from now to 2010, the demand for regular commuting parking and transfer will gradually emerge during this period, and spontaneous demand will dominate; (2) Long-term - During the period from 2010 to 2020, the basic network of rail transit will be completed, the attractiveness and service level of Shanghai's public transport will be greatly improved, the proportion of passenger traffic in public transport will increase rapidly, and there will be spontaneous and government-led demand; (3) maturity Period - After 2020, the parking transfer system is an integral part of the city's comprehensive transportation system. The coordinated development of mobility and public transportation will lead the adjustment of urban planning layout and outward migration of population. The public transportation-oriented TOD land development model is fully utilized.
The parking transfer system includes a parking and transfer fee system, a parking reservation system, an off-site guidance system, an on-site guidance system, and a location inquiry system.
