The long-distance commute to school caused by urban sprawl and the car-oriented urban construction model are key factors leading to primary/middle school students being picked up by their parents in cars. Encouraging those students to take rail transit can reduce their dependence on cars. This paper uses a stepwise regression based on rail-transit swipe data to explore the influence of the built environment on rail-transit commuting characteristics in Wuhan, and uses a geographically weighted regression (GWR) model to analyze the spatial heterogeneity of significant influencing variables. The study found that: (1) 60% of students are one-way commuters; (2) 88.6% of students travel less than 10 km; (3) the floor area ratio, bus station density and whether the station is a transfer station have an obvious positive effect on the flow of commuters; (4) whether the station is a departure station has a positive effect on the commuting distance, but the mixed degree of land use and road density have a negative effect on the commuting distance. This research can assist cities in formulating built environment optimization measures and related policies to improve school-age children's use of rail transit. This is important in the development of child-friendly cities.
城市蔓延和汽车导向的城市建设模式导致的远距离上学通勤是导致中小学生被家长开车接送的主要因素。鼓励这些学生乘坐轨道交通可以减少他们对汽车的依赖。本文使用基于轨道交通刷卡数据的逐步回归方法，探讨了武汉市建成环境对轨道交通通勤特征的影响，并使用地理加权回归（GWR）模型分析了显著影响变量的空间异质性。研究发现：（1）60%的学生是单程通勤者；（2）88.6%的学生出行距离小于 10 公里；（3）建筑面积率、公交车站密度和车站是否为换乘站对客流量有明显的正向影响；（4）车站是否为出发站对通勤距离有正向影响，但土地利用混合度和道路密度对通勤距离有负向影响。本研究可以协助城市制定建成环境优化措施和相关政策，以提高学龄儿童对轨道交通的使用。这对于儿童友好型城市的发展非常重要。
