Abstract

The invention relates to a traffic information management server managing the provision of traffic information to a plurality of navigation terminals and a navigation terminal. In accordance with a request message of the traffic information at the navigation terminal, the traffic information management server extracts the traffic information including the location ID of a moving object at the path, the traffic information and reliability corresponding to the location ID from a traffic information database, then generates traffic news and sends the traffic news to the navigation terminal. The traffic information management server also updates the reliability corresponding to the location ID in the traffic information database according to the traffic feedback information at the navigation terminal. The invention relates to a traffic information management method and a navigation method. According to the invention, the navigation terminal can send feedback information to the traffic information management server to test the reliability of the traffic information. Based on the above traffic information management server and methods thereof, the electronic map quality of the navigation terminal can be improved and the cost of the navigation information services can be reduced.

Description

technical field [0001] The present invention relates to the field of navigation, in particular, a traffic information management server that manages and provides traffic information to multiple navigation terminals, a navigation terminal that searches a moving object from a starting point to a destination, and guides the moving object, and a corresponding method . Background technique [0002] Today's navigation terminals carrying electronic maps can search for routes based on geographic and traffic rule information stored in electronic geography on media such as hard disks or DVDs. By inputting the start and end points, the user can select a route according to the calculation results of the navigation terminal. During the navigation trip, the system tells the user the path to drive, such as which intersection to drive to, etc. The data used for route calculation comes from the database in the electronic map, which is generally updated several times within a year.
