Network Creation and Travel Time Calculation of Pedestrian Flow in Urban Mass Transit Station

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.
