轨道车站交织区栏杆设置有效性分析

引入交织强度、交织区内的交织点密度和行人偏移率3个评价指标,通过受控试验定量分析交织区栏杆内区域与栏杆后2个子区域的流量、交织区位置移动、交织区面积变化及偏移率特征.然后以栏杆设置是否促进交织区人群行走有序性和是否发挥限流效果作为交织区栏杆设置有效性评价标准,提出判断流程.利用上海市2个轨道站点的栏杆设置案例定量评价栏杆设置的有效性,期望对轨道站交织区栏杆的规划设计提出定量分析方法.

The Validity Analysis of Railings Set in Pedestrian Weaving Zone in Railway Stations

This paper mainly introduces three evaluation indexes: pedestrian weaving intensity, density factor of weaving points in pedestrian weaving zone and pedestrian trajectory offset ratio. By means of controlled experiments, some parameters are analyzed quantitatively, namely the volume of the areas inside railings as well as two sub areas behind railings, the location of the pedestrian weaving zone(PWZ), the area of PWZ and the value of pedestrian trajectory offset ratio. Then, the judgment standards of whether setting railings makes pedestrian flow orderly and whether the railings play a role of current limiting were put forward, along with the judging process. Afterwards, two Shanghai urban rail transit stations in Shanghai were selected for case study, evaluating the validity of setting railings. It is anticipated that this research will put forward a quantitative analysis method for the planning and design of the railings.
