This study investigated the pedestrian crossing behavior at midblock crosswalks, in Istanbul.
Data were compiled from field studies at four selected crosswalks that were on one-way streets. Three of the crosswalks were located on three-lane streets while the other one was on a two-lane street. By using two-hour video recordings at each crosswalk, information was collected about pedestrian crossing preferences, pedestrian platoons both at curbside and during the crossing, traffic characteristics including volume, crosswalk occupancy and illegal parking, and pedestrian characteristics comprising age, gender and distraction status. These data were stratified with respect to the number of lanes and two multinomial logit models for platooning and individual crossing behavior was estimated for each stratum.
The results showed that the likelihood of platooning increases as the traffic volume and platoon size increase. Moreover, pedestrians who waited for little or no at the curbside and started to cross when one or more lanes were occupied generally lost time during the crossing. In terms of policy, the formation of platoons should be prevented by enforcement or demand-responsive traffic signals with push-to-walk buttons, etc. Overall, the study revealed that the presence of midblock crosswalks is questionable.
本研究调查了伊斯坦布尔中央横道的行人过街行为。
数据来自四个选定的路口的实地研究,这些路口都位于单行道上。其中三个路口位于三车道街道上,另一个路口位于双车道街道上。通过在每个路口进行两小时的视频记录,收集了有关行人过街偏好、路边和过街时的行人队列、包括流量、横道占有率和非法停车在内的交通特征以及包括年龄、性别和分心状态在内的行人特征的信息。这些数据按车道数量分层,并为每个地层估计了队列和个人过街行为的多项二项逻辑回归模型。
结果表明,随着交通量和队列规模的增加,队列形成的可能性增加。此外,在路边等待很少或没有等待,并且在一个或多个车道被占用时开始过马路的行人通常会在过马路时浪费时间。就政策而言,应通过执法或需求响应式交通信号(如带“按下走”按钮的交通信号)来防止队列的形成。总的来说,这项研究表明中央横道的存在是值得怀疑的。
