This study examines the influence of the built environment on trip-chaining behavior. Based on weekday travel in the Halifax Regional Municipality, we develop four separate models of tour complexity, each corresponding to a specific type of tour. The average number of trips per tour is regressed against built environment characteristics while household, personal, and tour-specific characteristics and residential self-selection are controlled. We apply ordinary least squares regression and spatial lag models and use a comprehensive set of density, diversity, design, and accessibility metrics near home and workplace. The results indicate that higher accessibility and mixed land-use is associated with simpler home-based, non-work tours. Workers residing away from opportunities make complex tours near workplaces located in high accessibility areas. Auto users make more complex tours. Also, most workers make complex commute tours compared to home-based or work-based non-work tours. In general, individuals compensate for the poor accessibility of residential locations by making complex tours, relying on auto, and chaining non-work trips with commuting. The significant role of attitudinal variables is also observed, thus revealing the presence of residential self-selection in trip-chaining behavior.

建筑环境对旅行连锁行为的作用：对新斯科舍省哈利法克斯工人和非工人的调查

本研究考察了建筑环境对出行链行为的影响。基于哈利法克斯地区市政府的工作日旅行，我们开发了四种不同的旅行复杂性模型，每种模型都对应于一种特定的旅行类型。每次旅行的平均旅行次数根据建筑环境特征进行回归，同时控制家庭、个人和旅行特定的特征以及住宅自我选择。我们应用普通最小二乘回归和空间滞后模型，并在家庭和工作场所附近使用一套全面的密度、多样性、设计和可达性指标。结果表明，更高的可达性和混合的土地利用与更简单的以家庭为基础的非工作旅行有关。远离工作机会的工人在位于高可达区域的工作场所附近进行复杂的旅行。汽车用户进行更复杂的旅行。此外，与基于家庭或基于工作的非工作旅行相比，大多数工人进行复杂的通勤旅行。一般而言，个人通过复杂的旅行、依赖汽车以及将非工作旅行与通勤联系起来来弥补居住地点的可达性差。态度变量的重要作用也被观察到，从而揭示了在旅行连锁行为中居住自我选择的存在。
