Disclosed is an analytical method for typical running routes in urban traffic, comprising steps as follows: (1) setting a road net topology structure as G = (V, E), vehicle information of every road junction at a corresponding certain time as R = (Ri|ii—(1,n)), judgment threshold of hotspot junction as k and judgment threshold of typical running route as k', (2) generating first sorting typical running routes between hotspots, which comprises obtaining a hotspot road junction aggregate by filtering road junction volume, in regard to vii—V' and Hii—H, generating a running route aggregate W' between the hotspots and obtaining a first sorting typical running route W'' by calculating the occupancy of the route according to the generated route W', (3)initially selecting the clustering of the first sorting running route and the generating of the traffic junction merger routes in every clustering aggregate according to the method to obtain the typical running route aggregate W with different particle sizes. The invention is short in processing period, low in cost and high in efficiency, and can reflect the change of the traffic conditions by calculating the typical running route.
