Regional Intercity Railway Planning Method Based on Individual Travel Path

This paper considers the concept that Mobility as a Service (MaaS) and investigates the intercity railway network design problem. The travel demand with individual features and the transport services with time windows are taken into full considerations. Transportation infrastructure, transport services, and travel demand are connected on a space- time network. Assuming that all links exist, the study takes intercity railway, urban rail transit, and road infrastructures and services into account, and obtains several feasible paths from the origin to destination within the travelers' time window for each type of travelers. The integer linear programming model is then designed to minimize the total generalized cost for all travelers and investment on the network. With identical physical links and transport services, the study analyzes three scenarios with same number of travelers and different demand features and verifies the significance and effectiveness of the model. The results show the proposed intercity railway planning method well reflects different types of travel demand and maximize total benefits in terms of travel time and investment, which also provides a new perspective for regional intercity railway planning
