Vehicle navigation method based on multi-information sources dynamic traffic information

Abstract

The invention discloses a vehicle navigation method based on dynamic traffic information from multi-information sources. The vehicle navigation method forms actual road traffic conditions by processing and integrating the dynamic traffic information from various information sources. The method provides users with three different navigation paths by using different combinations of static traffic information and the dynamic traffic information according to user selection, can process and integrate the dynamic traffic information from the various information sources and form the actual road traffic conditions, and plans paths which have shorter running time and more accord with the actual conditions, so as to be capable of avoiding the roads with traffic accidents, roads with traffic congestion and so on.

Description

technical field [0001] The invention relates to a vehicle navigation method, in particular to a vehicle navigation method based on dynamic traffic information from multiple information sources. Background technique [0002] The problem of urban traffic is a problem that industrial developed countries have been troubled by since this century. At present, the economic, trade and social activities of cities in our country are becoming more and more busy, and the urban traffic has experienced unprecedented rapid growth. The traditional road traffic facilities can no longer meet the needs of modern society. The traffic problems in our country's cities, especially big cities, are extremely serious. If they cannot be effectively solved and fundamentally treated, they will definitely pose a serious threat to the sustained, rapid and healthy development of our country's economy. In order to solve the urban traffic problems in our country and improve the performance of the urban traf...

Problems solved by technology

[0003] The traditional method of vehicle navigation based only on the road topology cannot reflect the real traffic conditions of the road

For example, in the case of rush hour or traffic accidents, there will be traffic jams on some road sections, but navigation based on road topology alone cannot avoid such road sections; Passage, temporary prohibition of turning or temporary lane change and other road changes to guide traffic

Navigation based only on road topological structures also cannot respond to such changes in a timely manner, resulting in the planned navigation path being unfeasible

[0004] The traditional navigation method based on the dynamic traffic information of a single information source cannot fully reflect the real traffic conditions of the road due to the single information source, so the accuracy of the planned vehicle navigation route is relatively low

At the same time, the coverage rate of dynamic traffic information from a single information source is generally relatively low.

Therefore, there are relatively few dynamic traffic information that can be used, which also affects the quality of the planned dynamic vehicle navigation route, thereby affecting the effect of navigation.
