Passenger Flow Assignment Algorithm and Software Implementation of Pedestrian Streamline Network of Urban Mass Transit Station

摘要:

为实现符合城市轨道交通车站行人流线网络特点的行人设施客流分配，首先将分方向实结点时间阻抗与结点客流方向引入最短路径识别，将其嵌入连续平均法，建立了适用于城市轨道交通车站行人流线网络的客流分配算法.然后，利用C#和Matlab语言在AutoCAD环境下开发了相应的客流分配软件,并在此过程中提出了结点客流方向获取方法.算例表明，该算法能够实现考虑分方向实结点时间阻抗的城轨站行人设施客流分配；与TransCAD、VISUM相比，软件符合行人流线网络特点，操作简便.

Abstract:

In order to realize passenger pedestrian facilities flow assignment which conforms to pedestrian streamline network characteristics in the urban rail transit station, directional delaynode time impedance and node passenger flow direction were introduced into shortest path identification process. The above shortest path identification process was added to the method of successive averages and passenger flow assignment algorithm was constructed which is suitable for pedestrian streamline network in urban rail transit station. Corresponding passenger flow assignment software was developed by using C#.NET and Matlab in AutoCAD and the method to get node passenger flow direction was built in the development process. The example shows that the above algorithm can realize pedestrian facilities passenger flow assignment in urban rail station considering the directional delaynode time impedance, and, compared with TransCAD and VISUM, the above software conforms to pedestrian streamline network characteristics and is easy to operate.
