At present, the autonomous vehicle navigation system's main function is to deal with GPS receivers, gyro, mileage and other equipment Miriam received information, to complete the vehicle location and map-matching, and graphical display of vehicle location; according to user requirements planning the optimal destination routing; in accordance with the road and vehicle-generated position, issued a timely manner to users of voice or graphics commands to guide the way. However, due to the current road congestion, road construction, traffic control, such as real-time traffic information can not be reflected in the navigation system, fully autonomous vehicle navigation system is almost impossible to provide users with a very thoughtful and efficient air navigation services.There is an urgent need for real-time traffic information, such as traffic accidents, road congestion, road construction and inclement weather, etc., sent to the roadworthiness of vehicles, car navigation systems to support real-time dynamic navigation Gong in Beijing, the number of vehicles has reached 300 million in volume, the number reached 4.4 million drivers today, access route information, real-time traffic information, inquiries, public / commercial locations has become a growing demand to drive the crowd, while traveling on public transport bus lines to the crowd of query demand for the explosive growth. 2006 sponsors of the Beijing Municipal People's Political Consultative Conference Beijing traffic demand Wizard has done a more precise quantitative survey, based on the Capital Airport, Beijing Railway Station, Beijing West Railway Station, bus stations, commercial areas, community and other places issued 15,000 copies of the questionnaire Statistics show that 85.1 percent of respondents believe that the field: Beijing addressing inconvenient to ask the way, while being investigated in Beijing resident population, 67.1 percent of people also think that the inconvenience.In addition, according to Li Suli hotline statistics, the actual daily volume of telephone access to 13,000, as a result of telephone line is busy for the 6-7 million loss.In addition, the CPPCC members of the research proposal, also referred to the current Beijing taxi driver in the rapid urban development, but also in urgent need of the road guide to find the destination system to meet customer demand.As a real-time information exchange systems, dynamic traffic navigation system there are still a lot of development of space.Along with partners to further increase, the future navigation systems will be set traffic guidance, personal communications services in one multi-purpose booking interactive platform.
