Mobile Location-based Services Used In The Research Of Intelligent Transportation Systems

With the rapid development of society, the number that how much of cars people had is more and more. The traffic problem has been a important matter in out country. Applying modernizing technology means to manage city traffic enhance maneuverability and flexibility, makes better using for transportation and exert function efficiency of traffic systems to the best of its abilities, which is developing intelligent transportation systems; it is efficient ways of resolve traffic crowd.The ITS is a effective type to resolve the traffic problem, and the wireless location system can provide more information for the ITS. Otherwise, the design and develop that base on the GIS of the LBS system also can provide some information query and service. Therefore, in allusion to the efficient of the ITS from wireless location system, we research several technique such as TDOA location, base the heredity arithmetic of the TDOA, base the commix heredity arithmetic of the TDOA, GPS and difference GPS. We also make a location model which use the wrong-distance difference GPS.At one time, we investigation and archive a LBS flat which uses the GIS technique. The flat can provide some services for the ITS. So we design the exterior interface of the LBS and the GIS technique appliance on the LBS. For the investigation of GIS, the more important is the function model design, encapsulation and GIS space database. We investigate when we compile the codes.Lastly, the text introduce a configuration of the ITS which base on the wireless location technique. And design and illuminate the configuration of common traffic manage sub-system and traffic come out consultation and service sub-system.
