Traffic safety, traffic jam and environmental pollution are the Three Difficult Issues perplexing current international traffic field, especially serious with traffic safety problem.After adopting intelligent transport technology to improve road management level, be often only toll on traffic and just can reduce more than 30%, and the service efficiency more than 50% of the vehicles can be improved.For this reason, each developed country of the world competitively drops into substantial contribution and manpower, carries out large-scale intelligent transport technology development test.At present, a lot of developed country proceeds to this systematic research and test the stage of making the overall arrangement for.The main flow that intelligent transportation system will be 21 century transport development, this system can make existing highway utilization rate improve 15% to 30%.
U.S., Europe, day are the best countries of intelligent transportation system Application and Development in the world, and from they developments, the development of intelligent transportation system, has been not limited to the problems such as transport solution blocks up, traffic hazard, traffic pollution.Through the development of more than 30 years, the Application and Development of ITS obtains great achievement.U.S., Europe, Deng developed country complete ITS System Framework substantially, are giving priority to field large-scale application.Can say, the progress of science and technology has greatly promoted the development of traffic, and the proposition of ITS implementing, again for hi-tech development provides wide development space.
Along with sensor technology, the communication technology, GIS technology (Geographic Information System), 3S technology (remote sensing technology, Geographic Information System, GPS three kinds of technology) and the development of computer technology, the collection of transport information experienced by from manually collecting the history development procedure of single magnetic detector traffic information collection to the traffic information collection of the multiple acquisition mode combination of multi-source, domestic and international progressively going deep into transport information treatment research simultaneously, statistical analysis technique, artificial intelligence technology, Data fusion technique, parallel computings etc. are progressively applied in the process of transport information, the process of transport information is made constantly to be developed and reform, more meet each management subsystem person of ITS, the demand of user.Information acquisition and treatment facility industry present following features:
Based on the car networking data collecting unit method characteristic of 3G network
1, the variation of information acquisition and processing mode
The mode of traffic information collection is divided into artificial acquisition mode and automatic acquisition mode.Automatic acquisition mode comprises magnetic detector (comprising inductive coil detecting device, magnetoresistive transducer etc.), fluorescence detector (comprising video detector, laser detector), microwave detector (comprising microwave detector and radar meter), surface conditions and load cell (misty rain detecting device, detecting device icy on road, wheel, axle load meter etc.).Along with the development of science and technology, automatic acquisition technology obtains continuous research, development and application.Various acquisition technique has respective merits and demerits, utilizes the carrying out of multiple acquisition mode to combine and gathers the focus and focus that transport information is research both at home and abroad at present.
Develop the Quality Control Technology of information, multisource traffic information fusion technology, the Multiple Time Scales forecasting techniques of information, Technique of Information Integration, compressionism and memory technology etc., substantially increase the kind that the precision of information and information provide.
2, the content of information and geographic range wide
The parameter limitednumber that different traffic acquisition modes gathers, such as inductive coil can only collect the cross section traffic parameter of the fixed locations such as the magnitude of traffic flow, occupation rate, speed; Video detector can only collect the traffic parameter of the fixed locations such as the magnitude of traffic flow, speed, occupation rate, queue length; Along with the combination of multiple traffic acquisition mode, the magnitude of traffic flow, speed, occupation rate, queue length, journey time, overall speed uniform cross section and road section traffic volume parameter can be obtained, while having enriched the collection content of transport information, also improve the range gathering geographic range.
Along with traffic data obtains the increase in source, transport information user is to the progressively raising of mass traffic information real-time demand.In recent years, gradually Distributed Parallel Computing technology, high performance computing service device and high performance data processing algorithm were applied among the process of mass traffic information both at home and abroad, improved the processing speed of information.
3, the precision of information acquisition and economy improve
Along with the development of the raising of magnetic and optical sensor technique, image processing techniques and location technology, the acquisition precision of transport information is also constantly improved.Meanwhile, along with in recent years to the research that deepens continuously of traffic detector configuration optimization technology, transport information be captured in the prerequisite of the comprehensive and dynamic of guarantee information under, also improve the economy of traffic information collection.This development and application being ITS system is laid a good foundation.Along with the maturation gradually of artificial intelligence, statistical study, fuzzy logic, chaology etc., have developed some information processing methods that are theoretical based on these and method gradually, substantially increase precision and the quality of information processing.
The fast development of data acquisition IT and the communication technology makes the issue of information be no longer bottleneck, and roadside is issued, mobile phone is issued, portable terminal is issued, internet is issued, car-mounted terminal is issued, etc., all there is huge application market.Visible, realize the explosive growth of transport information application, how obtaining original traffic data and being processed into transport information is accurately that it is crucial.
For the collection of real time traffic data, mainly contain two kinds of modes at present: one is static traffic detection mode, the fixed point detecting device mainly utilizing position fixing or video camera; Another kind is dynamic traffic detection mode.Usually, the fixed point detecting device being used for gathering traffic flow data has induction coil checker, ultrasonic detector, radar detector, photoelectric detector, infrared detector etc.Dynamic traffic detection mode refers to that the vehicle that position-based constantly changes or mobile phone are to obtain the data acquisition modes of the transport information such as real-time road speed and hourage.Dynamic traffic detection typical way comprises transponder, vehicle detects automatically, GPS (GPS) device and mobile communication etc.
Coil and video camera (video monitoring) are the exemplary means that fixed point detects.Coil is the one distortion of magnetic detector, and its dependence is embedded in the electromagnetic induction change of one or one group inductive coil generation under road surface, detects the situation of the vehicle passed through.This technology is very ripe, and precision is higher, is applicable to the road that the volume of traffic is larger.But also clearly, namely acquisition range is limited, spoilage is high, construction cost is expensive, long construction period for its shortcoming.The Typical Representative of this kind of data has " certain urban loop microwave detection history record data ", " certain urban road intersection detection history record data ".
Video monitoring is then utilize video camera as recording unit, by drawing the particulars of traffic flow to the image analysis in certain hour section.For the investigation of intersection traffic situation, often adopt in this way.The advantage of this method is relatively more directly perceived, can obtain transit information information the most completely; Shortcoming is that cost is high, data preparation workload large (needing a large amount of image processing work), sometimes fiduciary level lower (as oversize vehicle may block accompanying dilly etc.)." traffic video database ", " car plate picture database " that this kind of data typical case gathers as data hall etc.
As the Main Means of Dynamic Traffic Flow information acquisition, GPS technology is widely used abroad, domesticly also have excellent way, the company such as beautiful and intelligent developed can be commercial product.GPS is a kind of global, round-the-clock satelline radio positioning system, the spatial information such as three-dimensional coordinate, speed can be provided in real time, be characterized in that precision is high, speed is fast, but also have a lot of problem in practical application, be mainly manifested in exist gather blind area (as the road overhead under does not collect gps signal), sample size is little, construction and operation cost high.The typical case of this kind of data is as " certain North City taxi GPS location data ", " certain Shelter in South China Cities taxi GPS location data " etc.
Traffic information collection technology based on mobile communication utilizes the signaling information in cell phone network to analyze and calculates dynamic traffic situation, its feature may be summarized to be that routes coverage is wide, data acquisition advantage of lower cost, dispose convenient, data precision is more high.As a kind of emerging dynamic traffic detection means, this technology takes full advantage of existing cell phone network resource, and its practicality is just proved in the country such as the U.S., Europe and promoted.
Industrialized country, under the guidance of market economy, mostly experienced by the development that expanding economy promotes automobile, and the process that the development of automobile industry stimulates economic development, thus these countries achieve the epoch of motorize in advance.The such as traffic jam that motorize society brings, traffic hazard, the social concern such as energy-consuming and environmental pollution worsens increasingly, the economic loss that traffic jam causes is huge, make the U.S. that road equipment is very flourishing, Japan etc. also has to turn to from the thoughtcast only satisfied the demands by supply in the past take to supply, the techniques and methods of two aspect managed together is needed to improve the traffic problems be becoming increasingly acute, these industrial countries be based upon on wheel of the bus had both safeguarded motorize society in exploration, alleviate in the way of congested in traffic problem again, be intended to improve traffic by modernization science and technology reach and " ensure safety, raise the efficiency, environmental protect, economize energy " the ITS concept of object just progressively formed.
The continued change of human environment
Industrialized country is faced with day by day serious shortage of resources and environment deterioration problem in the process of industrialization, Development of Urbanization, this problem exists equally in developing country, since the 1950's, survival and development problem becomes the most urgent task that human society faces, and United Nations Conference on Human Environment in 1972 have passed " declaration on the Human Environment ".Intelligent transportation [4]
An inevitable outcome of urbanization productivity dynamics, by the rule of development of world economy, the level of urbanization reaches more than 30%, the economic develop rapidly stage will be there is, the developed countries such as the U.S., Japan, Britain, nineteen ninety the level of urbanization reach 75%, 77%, 89%, these countries, for the impact of transport development on resources and environment, progressively adjust communications and transportation Achtechture.These countries all experienced by the demand for meeting vehicle development, and Devoting Major Efforts To Developing builds traffic infrastructure (as 70,000 km highway planning of U.S.'s nineteen forty-four planning, substantially completed through 50 years one, but still produce crowded and block), while the resource occupation such as a large amount of soil, fuel oil and consumption, not only transport need is completely dissatisfied, but also causes vehicle exhaust due to the crowded discharge capacity sharp increase of road, not only economy brings about great losses, and brings baneful influence to environment.
60, since the seventies; because oil crisis and environment worsen; industrialized country starts to take to increase the benefit and transportation system management (TSM) for the purpose of economize energy and Transportation Demand Management (TDM) greatly develop large conveying quantity track and enforcement industry and traffic priority policy simultaneously; under the target of social sustainable development, adjust transport structure, set up and energy equilibrium is utilized and the optimized communications and transportation system of environmental protection.ITS is as comprehensive transport solution problem; the traffic and transportation system of new generation of protection Sustainable Socioeconomic Development and in accordance with natural environment; along with developing rapidly of infotech breeds development in developed country, after the nineties, become worldwide important development trend.
Infotech is intelligent
Traffic administration scientific, modernization, it is people's comprehensive regulation always, transport solution problem and the target of pursuing, early stage traffic signal control system device have employed electronics, sensing, the technology such as transmission realize scientific management, along with the development of science and technology, especially computer technology science and GPS, universal and the application of information communication, traffic monitoring control system, system for traffic guiding, information acquisition systems etc. have played great role in traffic administration, but these technology are merely implement scientific management to vehicle or road, scope is single, limitation, systematicness is not strong.
Since the later stage eighties, worldwide cold war terminates, and industrialized country is used for satellite navigation system that is military and national defence, information acquisition and put forward Intelligent traffic management systems
For system, computing machine control and management system, the new and high technology such as electronics and electronic communication technology turns to civil nature, military input also major part is transferred in the development and application of civilian technology, meanwhile, comprise the developing countries of China by peace, stable international environment accelerates the economic development of this country, the developing rapidly of economics of underdevelopment facilitates the industrial structure in world wide and huge change occurs, the traditional industry field of industrialized country is concentrated to developing country due to labor-intensive industry and loses obvious competitive edge, start to ferment the industrial market of opening up new and high technology content, under this international environment background, represent the signal that a field information revolution arrives, cause the very big concern in the whole world, Here it is " information highway ", and infotech obtains develop rapidly, especially international information network " internet " is set up, accelerate the process of global economic integration, 1994 start, world economy progressively enters the information revolution stage.
Information industry is arisen at the historic moment, and ITS is based on infotech, and melt other correlation technique and be applied on communications and transportation intelligent management and have its significant market, industrialized country and private enterprise put into this emerging industry one after another.U.S. government started in 1991 to invest the development research to ITS, and only the United States highways security bureau investment budgey of 1993 just reaches 2,010 ten thousand dollars; 19, Europe government investment 5,000,000,000 dollars is to EUREKA project.
Development strategy on July 31st, 2012, China's the 3rd Intelligent transport conference opens in Beijing, and science and technology department of Department of Transportation relevant responsible official has externally resolved 2012 to the 2020 transportation intelligent transportation development strategies completed in the recent period first time.
The focus that intelligent transportation develops as world today's communications and transportation, while support traffic management, more focuses on the demand meeting common people's trip and public's traffic trip, constructs the system of a green safety.Intelligent transportation is the developing direction of future transportation system, it be by the infotech of advanced person, data communication transmission technology, Electronic transducer technology, control technology and computer technology etc. effectively integrated apply to whole ground traffic control system and set up a kind of on a large scale in, comprehensively to play a role, in real time, composite communications transport management system accurately and efficiently.ITS can effectively utilize existing means of transportation, reduces traffic loading and environmental pollution, guarantee traffic safety, improve conevying efficiency, thus, is day by day subject to the attention of various countries.Through research and development and the application of more than ten years, Chinese intelligent transport technology has played positive role in numerous large-scale event.
New trend intelligent transportation future development will pay close attention to the people's livelihood such as Public Traveling, traffic safety demand more, more be applicable to China's national situation, region and industry characteristic, more need the participation of enterprise and societal forces, and autonomous innovation combined with integrated innovation." science and technology department of Department of Transportation vice chief of department Hong Xiaofeng says.
Intelligent transportation is the hot-point and frontier of world today's communications and transportation development, it relies on existing traffic infrastructure and delivery vehicle, by the Integrated predict model to technology such as present information, communication, controls, to build safe, convenient, efficient, green communications and transportation system for target, fully meeting Public Traveling and freight transportation diversified demand, is the important symbol of Modern Traffic forwarding business.
Abroad, Japanese wisdom roadnet, European green intelligent traffic, U.S.'s intelligent driving strategy are all the effective practices that intelligent transportation develops.In recent years, the intelligent transportation such as electronic stop plate, dynamic navigation instrument, electronic charging system without parking application also comes into Chinese life gradually.
Roadside control unit equipment is arranged on trackside and upper pavement surface respectively, for reading the data such as vehicle identification code in OBU, and pre-service being carried out to data, then sending the data to PDU, also relevant various data can be sent to OBU, it is the communication bridge between OBU and PDU.
Data processing unit PDU receives the relevant data sent of RSU, verifies and implements the operation of relevant calculation and control, or send relevant data by RSU to OBU to testing vehicle register.OBU, puts onboard exactly, is used for and the microwave equipment of RSU communication of roadside erection, time vehicle high-speed is by RSU, with microwave communication between OBU and RSU, just as our non-contact card, only apart from farther--tens meters of VS ten centimetres, frequency is higher--5.8GHz VS 13.56Mhz, when passing through, identify true and false, obtain vehicle, calculate rate, deduction toll.Through constantly development, OBU has departed from the restriction storing account and pay, and novel OBU, increases the function of an intelligent card read/write device, can insert one with the smart card of stored value card or account of stored value, from card, money be deducted.Be called as double-disk, the OBU of account that only has above is just called as one chip.
Distinct Chinese characteristics traffic safety, traffic jam and environmental pollution are the Three Difficult Issues perplexing current international traffic field, especially serious with traffic safety problem.According to expert's research, after adopting intelligent transport technology to improve road management level, be often only toll on traffic and just can reduce more than 30%, and the service efficiency more than 50% of the vehicles can be improved.For this reason, each developed country of the world competitively drops into substantial contribution and manpower, carries out large-scale intelligent transport technology development test.
Traffic system (ITS), refer to and the infotech of advanced person, data communication transmission technology, electron controls technology, computer processing technology etc. are applied to traffic transport industry thus the new transport system of a kind of informationization formed, intellectuality, socialization, it makes traffic infrastructure play maximum efficiency.This technology originates from the U.S. the eighties in last century, and the development in this field is all actively sought by each state subsequently.
" intelligent transportation is the field that a national conditions correlativity is very strong." Beijing Jiaotong University professor Jia Limin tells " science Times " reporter, since the intelligent transport technology starting eighties in last century, national governments and expert carry out localization and explore on the basis of American Studies content according to national conditions.
" to the requirement of traffic not only because of country, area, cultural difference and varying, even same traffic is because of the role of traveler---walking or the difference of driving, and different impressions and evaluation can be produced." Jia Limin says, " enter an intelligent transportation step and say that same role, because of the difference of individual disposition, also has different impression.Therefore, traffic is the closely-related field of behavior with culture and participant.”
