The scientific classification of urban multi-mode transportation network can obtain the characteristics of each hierarchy. Based on the analysis of single network classification index and the study of multi-mode network characteristics, the unified index of multi-mode network hierarchy is obtained as running speed, passenger transportation intensity, general travel costs and capacity, and the calculation model of the index is given. By K-means clustering analysis, the multi-mode transportation network in JianYe district of Nanjing is classified into 4 hierarchies (Express network, Main network, Minor Arterial network and Branch network), and the index threshold of each hierarchy is calculated. Moreover, the result of multi-mode network classification comparing the current situation with the demand increase shows that the demand increase has a great influence on minor arterial network and branch network, and express network has the least influence.
