Abstract

The invention discloses a vehicle dynamic path navigational system. The system consists of a traffic information acquisition subsystem, a communication subsystem, a traffic information comprehensive processing platform and a traffic information publishing subsystem, wherein the traffic information comprehensive processing platform processes and analyzes the traffic information data to obtain inducing information, the traffic information publishing subsystem publishes the inducing information to a site road, the communication subsystem is based on general packet radio service (GPRS) or code division multiple access (CDMA), the traffic information comprehensive processing platform is provided with a data analysis and forecast system and a dynamic path optimization and dynamic traffic flow balanced system. In the invention, the improved Dijkstra algorithm is utilized in the vehicle dynamic path navigational system, the road weight based on the travel time is considered, and the traveling path is optimized, the real-time traffic information and the inducing information are quickened to be published, thereby the traffic operating efficiency of a road network is effectively enhanced, the circumstance that the number of the vehicles exceeds the actual traffic capacity of the road is avoided, and the problem of traffic jam is improved.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to traffic flow measurement and control technology, in particular to a vehicle dynamic route navigation system. Background technique: [0002] In the prior art, the traffic navigation system cannot provide real-time dynamic traffic information. Mainly manifested in: the positioning electronic map data provided by the system is static and does not really reflect the current road traffic conditions. Traffic road condition information is collected by installing detection equipment such as loop coil detectors at key road sections or intersections, and then transmitted to the traffic monitoring center. Invention content: [0003] The object of the present invention is to provide a vehicle dynamic route navigation system, which solves the technical problem that the traffic navigation system in the prior art cannot provide dynamic traffic information and cannot provide an optimal driving route. ...
