    摘要:

    从行人流线角度出发,结合拓扑学原理,提出3种基本元素来抽象行人设施及生成设施内、外走行路径,并引入具有面积属性的实结点子模型,解决流线交织区域的疏散问题,进而构建完整的站内路网.通过现场观测给出2支流线交织区域的面积计算和拥挤度判断方法,并结合宏观交通软件VISUM,计算得到路径的通过流量、走行时间等指标,最后与微观仿真软件比较,说明本文方法操作的便捷性及应用于设计阶段的优越性.

    Abstract:

    From the perspective of pedestrian flow, a method is developed to analyze the collection and distribution capacity of pedestrian facilities’ layout scheme conveniently in urban mass transit station. According to the topology theory, three kinds of basic elements are created to abstract the facilities and form the travel path in and out of them, whilst the concept of “true node” which means a node with its area is proposed to describe the confliction of pedestrian flow. Through field observations, the method about area computing and congestion judging is set up in the conflict region of two intersectant pedestrian flow. Drawing support from software VISUM which is applied to macroscopic traffic, passenger flow, travel time and other index can be calculated. Compared to the microscopic simulation software, the convenience of this calculation model is illustrated especially in the design stage.
