Intelligent traffic expectation

In the world of intelligent transportation, traffic jams will no longer exist, instead of the flow of the flow of the transport environment.　　But to make the dream come true, intelligent transportation still needs to conquer a lot of puzzles. The reporter Guo Lu the intelligent Transportation system, which began to arouse the common expectation of government managers and travelers. Imagine a scene: living in Beijing Chaoyang District, a white-collar workers near the hospital, early in the morning 7 to go downstairs, driving, car GPs with beautiful voice broadcast today's weather and traffic conditions, then automatically chose a road smooth driving route. 30 minutes later, he hummed a song to drive to the center of the ITC parking lot, GPS real-time broadcast garage parking spaces, parking spaces are clearly more than sufficient.　　It was 10 minutes away from work and he had plenty of time to get a mocha latte at the Guomao Mall Starbucks.　　This is not the scene in 2020, in the National Intelligent Transportation System (Intelligenttransportationsystem, referred to as its) center laboratory Director, engineering Doctor Zhang Ke, this is the initial popularity of intelligent traffic after the obvious fact. The ideal world in the 2030 Liquidity study, published by the World Business Council for Sustainable Development, the intelligent transport system is defined as "a transportation-oriented service system based on and includes modern electronic information technologies such as Wired, wireless, and satellite." It is characterized by the collection, processing, dissemination, exchange, analysis and utilization of information as the main line, providing a variety of services for traffic participants.　　"This vast system will advance information, the technology of electronic communication, automatic control, computer and network is applied to the whole traffic system including city bus, BRT (rapid transit system), Subway, ferry, light rail, renting, expressway and so on, and can be integrated management and control of the transportation. Zhang can be interviewed by reporters that the intelligent transportation system is at home and abroad to solve the problem of urban traffic congestion is the best solution. "Through the intelligent transportation system, the real-time road condition is entered the information platform by the electronic camera, after the Monitoring center processing, the shunting task gives the traffic dispatch, and publishes the situation to the end user in real time." In other words, users can use mobile phones, car GPS, etc., the first time to master real-time road conditions. "" This is only the most basic situation, in the integration of intelligent transportation system, private car GPS, traffic monitoring center and Global Positioning System satellite will be networked, drivers can interact with the dispatch center to generate information, so that commercial vehicles, buses and taxis operating efficiency greatly increased, Control of vehicles across the country and beyond.　　"The challenge of a big city abroad: The stakeholder perspective reports that transport is the single biggest infrastructure challenge facing cities at all stages of development, and that heavy congestion can have huge economic costs for cities, which are 1% and 3% per cent of GDP in developed and developing countries respectively. Can save economic cost and solve the problem of congestion efficientlyIntelligent transportation system, so the city managers of all countries attach great importance to.　　A Japanese study reported that intelligent transportation can reduce the number of deaths in traffic accidents by more than 30% per year, reduce the amount of congestion in the early peak period by more than 10%, and improve the efficiency of transportation more than 50%.　　According to data from the city traffic administration of Cologne, Germany, the city center has reduced the number of 21 million kilometres a year since 1992, when the city opened its intelligent transportation System (the unit's travel itinerary), saving 18 million euros a year, rather than before the system was enabled. However, the rapid development of information technology today, intelligent transportation has not only represented the above definition. In the view of Zhang, "in the advanced stage of intelligent transportation, the vehicle is placed with a magnet sensor and a highly sensitive radar device to detect the location of the vehicle on the road, detect the speed and avoid obstructions." This is the highest level of intelligent transportation system, it can magically create a near no accident driving environment. "With a good vision, global investment in intelligent transportation is increasing." Data show: The U.S. federal government since 1990 began the development of intelligent transportation system, 20 years of investment to 30 billion U.S. dollars, will continue to invest 50 billion of dollars in the future, the Japanese government in 1996 and two years in 1997 for the development of intelligent transport system budget will be up to 16.1 billion yen,　　The budget for utility and infrastructure for intelligent transportation systems is 128.5 billion yen; The European Union has invested more than 28 billion euros over the years since it developed its intelligent transport system in 1984. Localization problem China began to develop the highway information system (ie, the early stage of intelligent transportation) 15 years ago. Data from China's Intelligent Transport Association show that as of December 31, 2008, there are as many as 31 cities in China that have completed or are building intelligent traffic management systems. Among them, 2008 Beijing in the City intelligent Traffic Management system total investment of 108 million yuan, by the Beijing Transportation Development Research Center independent development.　　According to China's Intelligent Transport Association data, to 2016, the national total investment in intelligent transportation will reach 107.8 billion yuan. Professor Chang, the former deputy director of the Beijing Municipal Bureau of Traffic Management Geriren told reporters, "large and medium-sized cities in the general presence of congestion crux mainly from the setting of traffic lights." such as the morning and evening peak, normal road traffic lights when the length of the basic unchanged, increased the vehicle's stay time, through the intelligent transportation system can quickly improve the traffic capacity. "" At present, the traffic system of the domestic city because of the very few uses the traffic light induction control and the half induction control system, at the intersection turn cannot give priority to keep the green light. In the section with induction detectors, the traffic flow of the direction of the green light with automatic induction growth flashing time, the flow of small direction is to increase the flashing time of red light, to use this shunt congestion time.　　"Geriren said. It looks beautiful. "Intelligent transportation", but in China frequently "ineffectiveSpirit. The huge investment does not mean the improvement of traffic. During the Guangzhou Asian Games, the subway is free for a week BRT, taxi vacancy rate is high, the subway is packed; Hangzhou in the trial BRT, the city Road card fees and other information systems, every day around 4 o'clock in the afternoon rental shift period still can not hit the car, the West Lake along the Lake Road Block 2, 3 hours are normal　　Even in Beijing, where the highest levels of intelligent traffic, bus and subway have taken over most of the trip, the 1-hour traffic jam is commonplace. In the concept of intelligent transportation system, its primary stage is the intersection of urban transport network-like, the ground, underground traffic transfer, BRT, light rail, subway in all directions, people can choose the appropriate way to travel according to the road situation at any time.　　The traffic construction in Beijing, Shanghai, Guangzhou and other cities is not lack of transport facilities and passenger tools, why are they still indigestion? "A prominent feature is that the domestic bus station information is not complete, most bus stops can not provide passengers with the transfer or when the bus arrival tips, which often increased the traveler's transfer time, forming a transfer point of the congestion state, transfer points are generally located in the central area, resulting in a larger road congestion.　　Geriren. In cities that use intelligent public transport systems, in Cologne, Germany, the bus stop has an electronic information display across the entire operating network, which not only allows passengers on the platform to understand the exact arrival time of the vehicle and transfer information, but also to learn about the traffic events and the major events of the future from the title Information column,　　Convenient for passengers to travel.　　In Beijing, Shanghai, Guangzhou and other cities in the country, in addition to the BRT through the road sections, most of the bus stop can not realize the electronic information. In addition, Jamiehoughton, an expert on intelligent transportation systems at IBM's global Technology Service, told Caijing National Weekly that "while most cities are developing intelligent transportation systems, they are influenced by a variety of factors, such as the stage of urban development, physical characteristics, the level of existing transport infrastructure and public preferences." , the nature of the challenges faced by each city and the solutions that are feasible are different.　　"For example, in the rugged mountain city, congestion tends to occur at toll stations, and in coastal and economically more developed cities, congestion usually occurs during morning and evening rush hours." However, the domestic urban intelligent transportation system platform often appear homogeneity of the situation, and even the North and South cities successively to foreign companies to buy the same set of intelligent transportation system software.　　The two cities in the same province, because there is no unified information exchange, interactive networking platform, can not finally achieve road information integration. Another reason for the "failure" of intelligent traffic is the surge in private car travel rates. "China is still in the primary application stage of the intelligent transportation system, and there are few studies on the choice behavior of travelers." And in Beijing and other private car travel ratio of the city, the intelligent Transportation System can only guide the traffic flow, but also can not do the prediction of the traveler, so often also led to the selectiveWall。　　"said Wang, deputy researcher at the Department of Industry and Economic research at the Development Research Center of the State Council. "Now the impression of intelligent transportation technology is that you can get a real time road forecast by mobile phone before you leave, but it will change the road in the future." If quite a few of the people in the House know that a certain route is going to be stuck in 30 minutes, and a considerable number of people choose to bypass, the result is that road after 30 minutes is actually very smooth, because there are a lot of people who have to go through that road to choose the prior diversion, 30 minutes after the original forecast of the road is diverted to the past traffic blocked. Therefore, now intelligent transportation to solve not only the problem of predicting road conditions, but also to predict the driver's response. For example, Guangzhou Asian Games during the subway congestion, this is entirely by the choice of passengers to travel mode caused. "Wang said.
