Description
Technical Field
The invention relates to an intelligent traffic management system, in particular to an intelligent traffic management system and method based on a vehicle-mounted intelligent terminal.
Background
The intelligent traffic system is a comprehensive traffic management system which is established by effectively integrating an advanced information technology, a data communication transmission technology, an electronic sensing technology, an electronic control technology, a computer processing technology and the like and is capable of playing a role in a large range and all around, and is real-time, accurate and efficient.
The problem of traffic congestion does not exist in the big cities of countries in the world. Taking the developed U.S. as an example, the annual vehicle kilometer number increases at 77% during 1976 to 1997, but the increase in the contemporaneous road construction mileage is only 2%, and 54% of the vehicles are in a crowded state during the peak period in urban traffic. Due to traffic congestion, people spend more time on duty than usual by 1.5h each day, and the commercial vehicles are delayed in traffic transportation, so that the transportation cost is increased. However, limited land and economic constraints make road construction impossible to achieve relatively satisfactory mileage, and therefore, it is necessary to improve the traffic capacity of a traffic network without expanding the scale of the network. Therefore, modern information and communication technologies need to be comprehensively applied to improve the level of traffic management and the efficiency of traffic transportation.
At present, developed countries such as the united states, western europe, and japan compete with each other for investing a large amount of capital and manpower in order to solve traffic problems facing each other, and research and implementation of intelligentization of road traffic transportation is started on a large scale. In China, a large amount of manpower and material resources are also being input into governments of China and some places for researching and establishing an intelligent transportation network, for example, Beijing is actively integrating various transportation information resources, constructing an intelligent transportation system, planning to build a lot of key projects such as a traffic one-card, highway networking charging, non-stop electronic charging, inter-provincial long-distance comprehensive passenger transport hub information system and the like, greatly promoting the development of taxi calling market, and constructing public trip information service demonstration projects such as bus dynamic information acquisition and release based on electronic stop boards, motor vehicle navigation based on floating car dynamic information acquisition, parking guidance based on parking lot dynamic information acquisition and the like.
With the research and development of intelligent traffic management technologies, many individual technologies are relatively mature (for example, vehicle positioning technology using GPS, black box technology for determining vehicle operation state, electronic toll collection technology without parking, and the number of passengers on a bus stop collected by using an IC card device, etc.), it is noted that simple stacking of these technologies cannot constitute a truly effective system, and a truly informative intelligent traffic network can be constituted by integrating appropriate technologies. At present, no more perfect technology and scheme exist in developed countries or China, and the more perfect technology and scheme can be used for timely, accurately and finely contacting all nodes (private cars, buses, taxies, commercial operation cars, official cars, emergency cars, rail vehicles, roads, signal lamps, electronic bulletin boards, electronic stop boards, toll stations, parking lots, traffic monitoring centers, traffic management departments, mobile acquisition terminals and the like) involved in traffic, so that an intelligent traffic network and a traffic 'neural network' are really built.
The wireless mesh network is a novel network structure based on multi-hop routing and peer-to-peer network technology, has the characteristic of mobile broadband, and can dynamically and continuously expand, self-organize network, self-manage, automatically repair and self-balance. Its core guiding idea is to let every node in the network send and receive signals.
