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

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.
