基于出租车GPS数据的城市居民出行行为分析

摘要

传统的居民出行行为研究大多采用问卷调查的方法，费时费力。本文利用出租车GPS数据对居民出行行为进行分析，针对工作日和休息El两种情况分别作了研究。研究结果表明工作日的居民出行行为主要是通勤出行，其最主要的出行时间段为7：00—9：30和17：00—19：30，出行空间分布主要是居住地和工作地；而休息日的居民出行除了0：00—7：00时间段较少以外，其他时间段的出行分布平均，出行空间分布集中于商业娱乐休闲等区域，分析结果更加真实可靠。%Questionnaire survey is mostly used in traditional researches of the travel behaviors of the residents which are wasting time and energy, while in this paper, the travel behaviors of urban residents in working days and rest days are studied based on the taxi GPS trajectory data.
