"Intelligent transportation is a field with strong national conditions." Jia Limin, a professor at Beijing Jiaotong University, told the Science Times that since the 1980s, governments and experts all over the world have been exploring localization according to their own national conditions and American research contents.
"The requirements for transportation are not only different due to different countries, regions and cultures, but even the same traffic situation will have different feelings and evaluations due to the different roles of travelers-walking or driving." Jia Limin said, "Further, the same character will have different feelings due to different personal temperament. Therefore, transportation is an area closely related to culture and participants' behavior. "
The biggest traffic problem is the large population. In addition, the composition of traffic flow is also very complicated. In addition to the huge flow of motor vehicles, pedestrians and bicycles, there are more and more modes of transportation such as bicycles and tricycles.
Wang Gang, director of the Traffic Information Service Center, told the Science Times reporter: "From the perspective of urban structure, the urbanization process in China is also very different from that in foreign countries, mainly reflected in the differences in urban structure and road network." Compared with new york, London, Tokyo and other representative international cities, the urban functional areas of foreign cities are relatively scattered around the city center. Few cities are as concentrated as Beijing, with nearly 10 million people living and working in the center of small cities, and the traffic pressure of cities is highly concentrated in this area. This is a prominent feature of China's traffic compared with foreign countries.
After decades of construction and improvement, Beijing's road network has basically formed a ring and radial road network. Because the urban population density has been maintained at about 27,000 people/square kilometer for a long time, the urban population agglomeration has further intensified and the population flow is large. Building an intelligent transportation system has become the only way for the sustainable development of Beijing's transportation.
During the 2008 Beijing Olympic Games, there will be 120 traffic signals around Olympic routes and Olympic venues controlled by this system. In addition, a comprehensive traffic monitoring system is constructed, which includes three subsystems: video monitoring, traffic flow detection and traffic violation detection. At the same time, 80 TV monitoring points, 15 sets of automatic traffic incident detection systems and 80 sets of digital video systems have been built around the Olympic venues and related roads.
At the beginning of 2008, one of the focuses of Beijing residents' attention-about Beijing traffic, various media reported a news that the electronic toll collection system for beijing expressway road network will be opened soon. Drivers in Beijing can use the national standard card supporting the new system to swipe their cards at expressway (ETC) in Beijing without stopping, or they can use the Beijing municipal bus card to pay by swiping their cards (MTC) in the new system.
