城市综合体对社区居民出行行为影响研究

城市综合体作为一种高度复合的新型开发模式，通过改变社区建成环境，对居民日常活动产生了潜移默化的影响.本文从交通规划者视角，对城市综合体产生的社区居民出行行为影响进行了研究.基于问卷调查数据，通过倾向得分匹配预处理，弱化个人信息对于出行特征分析的干扰，以有城市综合体的社区居民自陈述的出行变化作拟纵向分析，初步把握城市综合体对社区居民出行特征产生的影响趋势.而后对有无城市综合体两类社区居民的出行数据进行对比分析.结果显示，城市综合体开发模式可有效促进居民产生更多的短距离慢行出行替代机动化长距离出行以满足弹性需求.本研究可为城市综合体区别于传统单一用地开发模式的交通系统配置提供方向指导.

Thinking on Development Strategy of Road& Waterway Transport ITS in China

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.
