Amazing Intelligent Transportation
According to the Beijing Traffic Management Bureau of Statistics data show that the rapid growth of motor vehicles is much higher than the construction of road traffic, then how to solve traffic congestion problems?
Intensive family car trip
1-11 months of last year's vehicle sales exceeded 10 million, an increase of 42.39%. Motor vehicles in Beijing from 3 million to 4 million spent only two years and six months, this growth is the transportation construction in any case can not match.
Yang, Tsinghua University, Research Associate, Institute of Transportation analysis of traffic jams formed Emerging Artists reasons that: "motor vehicle ownership and use of excessive growth, and road construction, traffic management, energy and talent development of the reserves can not keep up the speed of motor vehicles. In particular, the use of a motor vehicle, family car travel, Beijing, intensity (frequency and distance of travel) is 8 times the family without a car, so that relatively great pressure on road transport. "
Frequency of use of motor vehicles is a very important factor, only "four million" figure does not tell the whole story. Sample survey data show that the frequency of use of each car 5 times higher than the U.S., which increases the likelihood of traffic congestion.
According to deputy chief engineer of the Ministry of Communications Research Institute, Transportation Research Center, Jiang Yulin, director of sustainable development description: "The ownership of motor vehicles and road construction is unbalanced, and we are the construction of urban road space is constrained resource conditions, and only 10 % -15% of the urban space can be used for transportation construction. Beijing rapid rate of population growth, many of the current road network is compressed the original transform walking and bike paths, there are historical problems. "growth and use of motor vehicles is no doubt become the most direct reason for traffic jams.
In fact, any international city has undergone a rapid growth as a result of motor vehicle traffic congestion stage. Data shows that the late 70s of last century, the Tokyo motor 300 million, far more than the current congestion in Beijing, known as the "commuter hell." 1995, Seoul, South Korea reached 2,000,000 vehicles, already crowded, almost to the extent could not leave. Currently, the total motor vehicles in Tokyo nearly 800 million, but the traffic is better in Beijing, this is why?
Some experts believe that international experience shows that urban transport can be optimized through the management structure, differentiated charging policy to take reasonable limit car, the implementation of measures such as tail number limit line can ease the congestion to some extent.
Intelligent Transportation to improve road traffic management is to improve the utilization efficiency of urban road system, an effective way. According to Jiang Yulin describes: "the major cities are using the latest information technology to build intelligent traffic management system, GIS system management bus lines, installation of the bus map, e-stops, visual query to achieve the bus." These technology to facilitate people's travel. Such as Chang'an new traffic probe, which can automatically measure traffic junctions, thereby controlling the traffic lights change, is the visual impression of intelligent transportation.
Young Emerging Artists stressed: "Intelligent Transportation should be a full range of social services for the whole system, traffic data and related transportation information should be open to the entire community." Jiang Yulin who agree with this attitude, "The government should support intelligent transportation, cooperation on strengthening the management to change the public security and traffic situation of asymmetric information and data, better integration of traffic information and transit information. "
However, the traffic problem is a matter of economic, social, cultural and administrative complex system problems, many structural problems can not simply rely on can not be resolved, such as information technology. Tongji Intelligent Transport System (ITS) Research Center, Yang Xiaoguang that "when the basic pattern of the city and traffic is determined, including the use of information technology to improve the traffic problems may well be one of the measures, but the technology is no different from drugs alone is not symptomatic . promote the Intelligent Transport System technology, to fully achieve the government, industry and academia combine attention to the service function of intelligent transportation systems and industrial properties.
