This application discloses a
train timetable optimization method for
urban rail transit networks considering transfer coordination, belonging to the field of
urban rail transit technology. The method includes: acquiring
network topology,
transfer station information,
train operation parameters, and passenger flow data; constructing a timetable optimization model and generating an initial timetable, considering constraints such as departure intervals,
station dwell times, travel times, and turnaround times, with the objective of minimizing the total
travel time and operating costs of passengers on the line; identifying the set of transfer stations and direction mappings based on the
network topology, and extracting
train arrival and departure events from the timetable; optimizing the train
time windows at each transfer connection point with the objective of minimizing the total
waiting time for transfers across the entire network, forming a time window contract; adding this contract to the optimization model and resolving it to obtain a new timetable; and outputting the final timetable by judging whether the improvement in transfer
waiting time has converged. This method effectively improves the overall service level and
economic benefits of multi-line networks while reducing computational complexity.
