摘要： 选取来自国际学术期刊的论文，以概述形式对城市交通理论方法、实证分析等学术研究成果进 行总结性介绍，旨在增强城市交通业界和学界对国际学术动向和研究热点的关注，促进学术交流。 《不同类型步行出行中行人热暴露风险及其影响因素——基于南京市GPS的性别实验》一文利用中国 南京市GPS步行轨迹数据，探讨不同性别及不同类型(实用性和休闲性)步行出行中行人热暴露的差异 性及其影响因素。研究表明：男性的步行速度与距离均高于女性，其平均热暴露水平和单位时间热暴 露水平也更高；实用性步行所处的实时气温与地表温度均高于休闲性步行，使得单位时间热暴露水平 更高，但由于休闲性步行持续时间更长，其累计热暴露水平反而更高。自然环境对热暴露的缓解作用 在不同类型步行出行中因性别而异：在实用性步行中，绿地对男性和女性均具有显著的热暴露缓解作 用；但在休闲性步行中，该缓解效应仅在女性中显著。

Abstract： A review of selected papers from international academic journals is presented to summarize research findings, theoretical approaches, and empirical analyses of urban transportation. The aim is to enhance the communication between industrial and academic fields in urban transportation, highlight international research focuses, and promote academic exchange. The paper titled Exploring pedestrian thermal risk exposure and its determinants among various types of walking trips: a gendered examination from a GPS- based study in Nanjing utilizes GPS-based walking trajectory data from Nanjing to examine the disparities in pedestrian heat exposure risk and its influencing factors by gender across different types of walking trip (utilitarian vs. recreational). The results show that male pedestrians walk faster and travel longer distance than female pedestrians, and they therefore experience higher average and per-unit-time heat exposure levels. Compared to recreational walking, utilitarian walking occurs under higher real- time ambient and ground surface temperatures, leading to greater per-unit-time heat exposure. However, because recreational walks are longer, their cumulative heat exposure could be higher. The mitigating effect of the natural environment on heat exposure varies by gender for different trip types: while green spaces significantly mitigate heat exposure for both men and women during utilitarian walking, such mitigating effect for recreational walking is significant only for women.
