| Abstract:The selection of the optimal path in the road network is one of the most basic application of the navigation. If Planning path's selection is reasonable, Efficiency of traffic can be enhanced greatly. This paper will study and try to optimize the algorithm A* based on the features of urban traffic network. Focus on traffic rules to improve the data model of digraph, at the meantime, put the characteristic of road traffic capacity on each section, that's how the calculation of section weight was modeling. |
