Abstract:

As a highly integrated development mode, urban complex is exerting a subtle influence on residents' daily activities by changing the built environment of community. From the perspective of transportation planners, this paper studies the impact of urban complex on residents' travel behavior. Based on questionnaire data, residents' personal information disturbance on travel behavior analysis was firstly weakened in data pretreatment through propensity score matching. A quasi- longitudinal analysis of changes in residents' travel behavior after moving to communities within urban complex was conducted using residents' self-reported data, thus obtaining a preliminary understanding of the trend of impact exerted by urban complex on residents' travel behavior. Then, travel data of two group residents, corresponding two types of communities that within and without urban complexes, was comparatively analyzed. The results show that, urban complex development mode may effectively promote residents to generate more short-distance trips with slow traffic rather than long-distance motorized trips, to satisfy their daily elastic demand. This research can provide directional guidance for transportation system configuration for urban complex, differing from traditional single-function oriented development mode.
