In order to calculate the approach degree of vectors even more accurately, clustering algorithm on the original level is improved by calculating space distance and angle space similarity of the vector, and thus can more accurately determine the extent of the vector integrated close to the cluster of vectors. Preferred combination of characteristics of road passenger transport hub nodes, the improved clustering algorithm example shows good results obtained. The method is practical for the optimization of road passenger transport hub node.
