The demand to alleviate urban traffic and reduce air pollution puts forward high requirements for green travel in public transportation. Thus, study of the feasibility of urban green travel in public transportation is necessary. This study focuses on it from two aspects: City level by complex network and individual level by structural equation model. As for the former, point of interest data on the spatial distribution of urban public transportation in Wuhan city are quantitatively analyzed. Then, a complex network of public transportation in Wuhan is constructed by using the Space L method, and the network characteristics are analyzed. Results show that accessibility coverage is mainly concentrated in the central urban area, and two significant central nodes exist, namely, Linshi and Zhaohu stations. At the individual level, 354 valid questionnaires and the structural equation model were used to explore the factors affecting individual intention of public transportation. Behavioral perceptual outcome, behavioral attitudes, and subjective norms have positive influences on the behavioral intention of public transportation, among which the behavioral attitudes are the most significant, and the subjective norms had the lowest influence. Some suggestions are proposed for Wuhan to improve urban accessibility and for individuals to increase green travel in public transportation.

The prevalence rate of sidewalk was currently one of an important index to assess the development on various international countries. However, according to the result of The Annual National Safe and Accessible Sidewalk Assessment project on urban roads that conducted in recent year by the Construction and Planning Agency, Ministry of Interior; the suitability of sidewalk setting still has many issues for improvement. This study focused on the current condition of urban sidewalk environment, and conduct analysis by utilizing the Structural Equation Model (SEM) to explore important variables that influenced on the suitability of sidewalk. According to the analyzed result of the SEM, the width and clearance height of sidewalk were important factors that influenced on suitability of overall sidewalk. Therefore, from the result, improvement on sidewalk should improve the width and clearance height in priority.
