Abstract:

Passenger flow assignment theory is the core technology of railway passenger transport product design, and is of great significance to the evaluation of the quality of train service network. This paper studies attributes and establishing method of time and space service network of train constructing from passenger train working diagram, based on analyzing multi- level passenger’s trains choice behavior. It concludes who expect the range of service time (expect the window of service time）and transfer frequency and time, arc sections resistance of network is also determined. The passenger flow assignment model of network reflecting diversified passengers’travel service demand is formulated, which suggests solving the reasonable train space-time service rout choice set of passenger with combinational algorithm composed of the window of service time search algorithm and Dijkstra algorithm. The paper then designs sub-algorithm of passenger flow assignment based on reasonable train space-time service route choice set. At last section, the paper takes passenger train diagram under relevant Beijing-Guangzhou high speed railway network as the initial space-time service network, and conducts passenger flow assignment and validates the effectiveness of the model and the algorithm.
