地铁车厢内乘客站立位置选择行为研究

基于地铁乘客在车厢内站立位置选择行为设计问卷并调查,引入信效度分析判断问卷及其结果的可靠性,分析乘客在车厢内站立位置的选择偏好和对座位的需求程度.针对乘客从车厢两端和车厢中部车门上车两种情景,将车厢内部站立区域划分为6部分,建立考虑乘客出行距离和车厢内立席密度的乘客站立位置选择基线—类别Logit模型,采用调查数据对模型参数进行估计并验证.研究表明,模型标定结果与调查数据较为吻合,可较好地刻画乘客的选择行为.此外,乘客对车门前区的选择概率随车厢内立席密度的增大而增大,而坐席区域和侧边区域则相反;乘客出行距离较长时,乘客选择坐席区域的概率对车厢内立席密度的变化更为敏感.

Pedestrian Choice Behavior Analysis of Standing Position in Subway Carriage

A questionnaire of pedestrian standing position choice behavior in subway carriage is designed and investigated, and the reliability and validity of the questionnaire is verified. Passengers’preference of standing position and the desire for seat are analyzed. The carriage is divided into six parts based on the two layouts in the carriage. A Baseline-Category Logit model is established by considering the trip distance of passengers and the standing density in the carriage. The estimates of the parameters are calculated by the survey data. The result shows that the proposed model can effectively reflect pedestrian choice behavior in subway carriage. In addition, the probability of choosing the front area near the door increases with the standing density in the carriage, but the seating area and the side area are opposite. The probability of choosing the seat area is more sensitive with the standing density in the carriage when passenger’s trip distance is longer.
