A Dynamic Passenger Assignment Model for High-Speed Railway Networks Based on Constrained Continuous Capacity

For high-speed railway (HSR) networks, the space-time passenger flow distribution plays an important role for determining and optimizing the space-time resource allocation (e.g., train scheduling). This study develops a modeling framework to predict space-time passenger flow distribution for HSR networks with rigid capacity constraints. In particular, the service capacity is approximated as a continuous variable, which is time-and-space-dependent under given track network for the HSR system. The travel demand to be loaded to the HSR network has two features besides the origin and destination stations: ticket-booking time and desired departure time. Following the principle of first-booking-first-served (FBFS), an assignment model is formulated with the rigid capacity constraints, where a later ticket-booking time might result in less available travel options. A solution algorithm is designed for solving the ticket-booking-time-dependent assignment model. The model and its applicability are illustrated with a large-scale Chinese HSR network example.
