Navigation system and method based on traffic information prediction

Abstract

The invention discloses a navigation system based on traffic information prediction. The navigation system is characterized by comprising a vehicle-mounted navigation terminal and a navigation server, wherein the vehicle-mounted navigation terminal comprises a GPS positioning module, an electronic map module and a navigation processing module, the navigation server comprises a real-time traffic information collecting module, a traffic information predicting module, a traffic information storing module and a navigation path planning module, the GPS positioning module is used for sending position information and speed information of a vehicle to the real-time traffic information collecting module, the traffic information storing module is used for sending real-time and predicted traffic information to the electronic map module, the navigation path planning module is used for sending navigation path information to the navigation processing module, and the navigation processing module is used for sending the processed navigation path information back to the navigation path planning module. The navigation system has the characteristics that influences of the future traffic road condition change and the road selection of the vehicle on traffic are considered so that a navigation path is relatively close to a real optimal path.

Description

technical field [0001] The invention relates to a navigation system and a navigation method based on traffic information prediction, belonging to the field of vehicle navigation. Background technique [0002] Vehicle navigation system includes vehicle positioning, electronic map and path planning. The problem to be solved in navigation is to determine the current position of the navigation object on the electronic map according to the relevant traffic information such as roads provided by the electronic map, and to search for the optimal route according to the navigation destination, traffic information and optimization goals set by the user. [0003] The traditional navigation system is mainly a stand-alone offline navigation system, which has GPS positioning function, pre-stored electronic map and navigation path calculation ability, and can navigate according to the road information provided by the fixed electronic map, and can also avoid frequent traffic based on histori...
