Traffic Impedance Optimization Method and Realizationfor Dynamic Route Guidance

Based on the real-time traffic data collection, a reasonable dynamic optimal path was obtained, and the traffic impedance optimization method was proposed by considering the driver''s travel behavior factors. The determining method of the dynamic priority level index of road on the basis of traffic state in real time was studied, and the transportation network model for dynamic route guidance was reconstructed, which led to the significant decline in the complexity of the road network. Based on multi-source real-time data, the traffic impedance optimal calculation method of dynamic route guidance was researched. Finally, the realization of the dynamic path of road network was achieved and its simulation analysis was conducted through the GIS platform. This approach was proved to be better fit in with the driver''s behavior, and had remarkable significance and operational advantage for the application of the improved Dijkstra algorithm into the dynamic route guidance.
