摘　　要：以武汉为例,通过整合地铁刷卡数据、用地、兴趣点(POI)、房价等多源大数据,比较多种地理回归方法构建建成环境对老年人轨道交通出行时长的影响模型,选取拟合效果最好的空间滞后模型(SLM)进一步探究不同地理圈层中影响老年人工作日及周末轨道交通出行时长的建成环境差异。研究发现:(1)老年人工作日和周末轨道交通出行平均时长分别为29.45和31.18 min,新城圈层轨道交通出行时长大于45 min的占比最高。(2)老年人工作日轨道交通出行时长与三甲医院可达性紧密相关,周末轨道交通出行时长与城市公园可达性相关性更大。(3)旧城圈层老年人轨道交通出行时长受建成环境的影响相对较小,轨道换乘是该圈层老年人轨道交通出行时长增加的主要因素。(4)随着地理区位逐渐由城市中心向外围扩展,影响中间圈层及新城圈层老年乘客轨道交通出行时长的建成环境要素逐渐增多,包括容积率、混合度、道路密度、各类公共服务设施可达性等。The provision of an age-friendly rail transit environment is one of the effective measures to solve the aging problem.Although several studies have explored the impacts of built environment on rail transit travel behavior,the temporal and spatial heterogeneity effects of rail transit travel behavior have rarely been considered.Taking Wuhan as an example,the rail transit travel behaviors of the elderly and built environment factors were accurately characterized by integrating multi-source big data,including bus intelligent cards,land use,point of interest(POI),and housing prices.Several geographical regression models with different spatial weights were constructed to investigate the impact of built environment on travel time of elderly rail transit riders.The spatial lag model(SLM)with the best fitting was selected to further reveal the spatial heterogeneity in built environment that affects elderly travel time on weekdays and weekends in different urban geographical circles.The results show that:1)The average travel time of weekday and weekend for the elderly is 29.45 minutes and 31.18 minutes,respectively,but there are more elderly riders living in the new town circle with travel time over 45 minutes.2)The travel time of the elderly on weekdays is strongly correlated with the accessibility of grade-A tertiary hospitals,but that on weekends is more related to the accessibility of urban parks.3)For the old town circle,built environments have relatively slight impact on the travel time of the elderly,the transfer of rail transit is the main factor contributing to the long travel time of the elderly.4)As the geographical location gradually expands to urban periphery,the number of built environment factors that affect travel time of the elderly in the middle and new town circle is gradually increasing,including floor area ratio,land use mix,road density,and accessibility of public service facilities.Based on the modeling results,the optimization suggestions on built environment and rail transit environment in differe
