Walking has been actively advocated as a simple and effective means to boost individuals' physical activity levels. Comfort, as one of walking needs, is also the major objectives for many street design guidelines and walking audit tools. However, a few studies only identified the major environmental factors in a piecemeal manner without providing an integrated view on pedestrian comfort for recreational walking. This study aimed to identify the major micro- and built environmental factors and reveal their relative importance. 420 questionnaire responses with concurrently monitored micro-environmental conditions were analyzed to formulate a path model that portrayed the interrelationships between pedestrian comfort, and perceptual and objectively measured street built and micro-environmental characteristics. Our results showed that pedestrian comfort could be directly evaluated by pedestrians' satisfaction of built environment, thermal sensation, perceived air quality and loudness. The influence of satisfaction of built environment alone was found to be comparable to the aggregate influences of thermal sensation, perceived air quality and loudness. Thermal sensation, perceived air quality and loudness were found to mediate the associations between objectively measured parameters and individual recreational walking comfort respectively. The findings provide valuable insights for urban planners to improve the comfort level of recreational walking in streets.

步行已被积极提倡作为一种简单有效的方式来提高个人的身体活动水平。舒适性作为步行需求之一，也是许多街道设计指南和步行审核工具的主要目标。然而，一些研究仅以零碎的方式确定了主要的环境因素，而没有提供关于休闲步行的行人舒适度的综合观点。本研究旨在确定主要的微观和建筑环境因素，并揭示它们的相对重要性。对同时监测微环境条件的 420 份问卷答复进行分析，以制定一个路径模型，该模型描绘了行人舒适度与感知和客观测量的街道建成和微环境特征之间的相互关系。我们的研究结果表明，行人的舒适度可以通过行人对建筑环境的满意度、热感觉、感知的空气质量和响度来直接评估。发现单独建筑环境满意度的影响与热感觉、感知空气质量和响度的总体影响相当。发现热感觉、感知的空气质量和响度分别调节客观测量参数与个人休闲步行舒适度之间的关联。研究结果为城​​市规划者提高街道休闲步行的舒适度提供了宝贵的见解。发现单独建筑环境满意度的影响与热感觉、感知空气质量和响度的总体影响相当。发现热感觉、感知的空气质量和响度分别调节客观测量参数与个人休闲步行舒适度之间的关联。研究结果为城​​市规划者提高街道休闲步行的舒适度提供了宝贵的见解。发现单独建筑环境满意度的影响与热感觉、感知空气质量和响度的总体影响相当。发现热感觉、感知的空气质量和响度分别调节客观测量参数与个人休闲步行舒适度之间的关联。研究结果为城​​市规划者提高街道休闲步行的舒适度提供了宝贵的见解。
