Urban Railway Accessibility

Effective use of urban rapid railway systems requires that the railway systems be effectively con-nected with other transportation modes so that they are accessible. This paper uses the logit model and data to analyze the factors influencing railway access choices in a railway choice access model. The results indicate that access time, access cost, and access distance are factors significantly affecting railway access choices. The user’s income significantly affects the probability of choosing to walk rather than to take a taxi, but is not related to choosing buses or bicycles. Vehicle ownership significantly affects the probability of choosing a taxi, but is not significantly related to the other modes. The conclusions provide an analysis tool for urban railway planning and construction.     

基于用户画像的大型冬季户外活动客流需求特征挖掘——以哈尔滨和长春国际滑冰雪马拉松为例

大型冬季户外活动日益增多,有必要分析客流需求特征,进行数据挖掘。基于客流需求调查,对客流需求特征和意向进行分析,得到人们可接受步行、排队等候时间阈值为20 min内,户外比赛时间设置3 h内,比赛期间应提供取暖和餐饮服务设施,赛场附近设置边走边看为主的观赛区域,满足观众需求。进而采用二阶聚类和层次聚类法分别建立三类群体的用户画像,通过聚类效果三维图、聚类轮廓系数、聚类用户画像特征三种指标进行综合对比评价,得出二阶聚类效果较好。建立三类标签云图,本地团体观赛型：本地中老年人居多,步行排队、观赛时间较短,建议合理规划中老年团体车辆落客区域,有序组织客流入场;结伴自由观赛型：在步行排队、观赛时间较长,建议设置娱乐休息点,吸引群体游玩;青年外地观览型;对于区域不熟悉,步行排队以及观赛时间中等,建议需要加强比赛区域内外的交通设施引导,合理规划公共交通站点、停车场等交通服务设施。
