Abstract: Exploring the performance of urban rapid transit network has certain significance on its planning, construction and operation.This paper expands the research field of complex network theory from rail transit to the whole urban rapid transit.It proposes the Space S modeling approach to overcome the practical significance problems with the features and path selecting method in the Space L.Taking the Changzhou BRT as an example, the paper analyzes the whole performance of urban rapid transit respectively in Space P and Space L using the indexes as calculating degree, clustering coefficient, path length.By analyzing the branches’ effectiveness with FBCR(Financial Benefit-Cost Ratio), this paper presents a branches’ selection method.Through the robustness comparison between urban rapid transit network and bus transit, the importance of the integration of the two modes is thus proved.
