The built environment and trip chaining behaviour revisited: The joint effects of the modifiable areal unit problem and tour purpose
本研究同时考虑可修改面积单元问题和出行目的，基于北京2010年综合出行调查数据，用逻辑回归分析不同空间单元下建成环境对三种出行目的（生存、维持、娱乐）的出行链模式的影响，并找出最有效的空间单元。
Empirical research that examines the built environment and travel behaviour has frequently found inconsistent results, which can be attributed to the modifiable areal unit problem (MAUP) and to different treatments of travel purposes. This study considers these two important issues simultaneously in investigating the association between the built environment and travel behaviour in Beijing, China. Using tours as the analysis unit of travel, this study classifies three tour purposes: subsistence, maintenance and recreation, and identifies seven different spatial units to address the MAUP. Based on data from the 2010 Beijing Comprehensive Travel Survey, this study uses logistic regressions to estimate the primary tour mode and tour complexity. The results identify the ‘ideal’ unit at which the built environment has the greatest association with tours of specific purposes. Such results inform how urban planning and transportation policies can effectively influence travel.
