- Abstract:
- At present, the research on the choice of urban residents travel mode mainly focused on the influence of individual attributes on the travel mode choice, ignoring the correlation analysis of urban built environment with travel mode. Three variables, including individual attributes, transportation supply attributes and urban size, were selected as exogenous variables in this paper. Five variables, namely travel purpose, travel time, travel preference, travel distance and travel mode choice, were selected as endogenous variables in this paper. The structural equation modeling (SEM) was used to develop the relationship between those influence factors and travel mode choice for urban resident. Three cities with different urban size were selected as research sample, and the developed SEM was identified and corrected using investigation data in three city. Four indicators, including the ratio of the chisquare degree of freedom, goodnessoffit index, adjusted goodnessoffit index, and root mean square residual, were used to test the goodnessoffit of the developed SEM. Finally, positive and negative influence and its degree of all influence factors on urban residents’ travel mode choice were obtained. The results show that the results of four indicators meet the adaptation criterion or critical value requirement, which indicates that the developed SEM is good. Gender, occupation and income level significantly positive influence on individual attributes. Whether the destination having a parking lot has significant positive impact on transportation supply attributes, which indicates that perfect parking facility and enough parking space will encourage urban resident choose car. Large and mediumsize cities have significantly positive impacts on urban size, which indicates that residents in large and mediumsize cities are likely to choose bus. Individual attribute, transportation supply attributes and urban size have significantly positive impacts on travel mode choice, and travel preference has also significantly positive impact on travel mode choice. These findings have important implications for travel mode optimization and for the ease of traffic congestion. 6 tabs, 1 fig, 23 refs.
