Abstract

The invention relates to a dynamic intelligent navigation method based on a 3G (3-Generation) network. The dynamic intelligent navigation method is characterized by comprising the following steps: receiving 3G navigation information from a 3G navigation module and building a multilevel hierarchical structure model by a navigation route planning and processing module; determining and describing a scale; creating judgment matrixes; calculating a feature vector, a feature value and a consistency check index of each judgment matrix and performing consistency check; calculating comprehensive weight and determining an optimal route according to a maximum weight rule. According to the dynamic intelligent navigation method, all routes are analyzed by a hierarchical analysis method according to the navigation information of the circulation quantity, the distance and the traffic light number of the 3G navigation module to select out the optimal route; by more accurately selecting out the time-saving and non-congested route, the convenience is brought to a driver and the shortcoming of incapability of accurately sensing the road conditions in real time in the prior art is overcome.

Description

technical field [0001] The invention belongs to the technical field of vehicle navigation, in particular to a dynamic intelligent navigation method based on a 3G network. Background technique [0002] With the wide coverage of the 3G networks of China's three major network operators across the country, people can more and more conveniently experience the changes brought by high-speed Internet to our lives. Taking China Unicom as an example, it has achieved 3G network coverage with a bandwidth of 7.2M nationwide, a 3G network coverage with a bandwidth of 21M in most urban areas, and a 3G network coverage with a bandwidth of 42M in the Pearl River Delta region. However, car navigation still relies on the solidified software in the navigator and the wireless traffic broadcast to perceive the road conditions. The information obtained in this way is not accurate enough, and the algorithm cannot accurately determine the optimal route. At present, the car navigation system mainly ...
