Living Circles Towards Green Travels: A Study on the Correlation Between Facility Layout and Travel Behavior

Against the backdrop of global climate change, the high rate of motorization in community transportation and its associated carbon emissions are pressing urban problems that urgently need to be addressed. As the primary transition zone between walking, cycling, and driving, 15-minute living circles have the potential to promote green travel. This thesis addresses the question of how facility layout within 15-minute cycling living circles can promote green travel. Based on three types of travel behavior space, a hierarchical and phased theoretical framework is constructed for the correlation between facility layout and travel behavior. This framework includes hypotheses regarding how three travel behavior sub-goals (increasing the green travel proportion of all-type facilities, avoiding long-distance travel for single-type facilities, and promoting green travel choices for single-type facilities) are influenced by six dimensions of facility layout (attitude, density, scale, diversity, accessibility, and road condition). By three empirical studies, via mobile phone data from Tangshan and a regression-clustering methodology, the thesis reveals the influence mechanisms of facility layout on travel.
