City’s public transportation network is established on the chains which made up by city’s streets and the nodes which include bus stations and crossings. The arrival time of buses are influenced by the departure intervals, the time of buses to park at stations, the time of buses to wait for the red light, the degree of roads’ crowdedness and so on. This paper quantifies the different factors’ levels in city’s public transportation as resistance, and used them as the weighing of the chains and nodes in the network. The city’s public transportation’s resistance is an important source of data in city’s public transportation network. In the light of optimal path, it can be used in the city’s public transportation network analysis, such as the analysis of transfer, the analysis of arrival ability, the analysis of equal line in time. It can be used to optimize the routes by guiding the bus companies to adjust the number of buses and the departure intervals. It also can provide scientific explanation to extend or to open new bus routes. In a conclusion, it is of importance to calculate the public transportation’s resistance to builds or perfects the network which complies with a standard of livable city.
