Intercity Train Operation Schemes Based on Passenger Flow Dynamic Assignment

This paper summarizes the research status of intercity train operating scheme. To precisely describe the interaction between passenger flow and operating scheme, it proposes assumptions of system closure, train type division, passenger flow dynamic assignment and selecting priority during the process of establishing model. Based on these, it describes relative variables and formulates the passenger flow dynamic assignment model to reflect the conversion process of different passenger types. Then it develops a multiple objective programming model considering maximum railway department revenue, the smallest passenger total expenditure and the maximum passenger demand. It also uses the genetic algorithm to solve the established multi-objective 0-1 integer programming model. Finally, a numerical example is provided to illustrate the effectiveness of this algorithm of model.
