Key Points

Develop an integrated framework combining microscopic train simulations and macroscopic optimization models to evaluate railway capacity using UIC 406 timetable compression during early infrastructure design stages.
Coupled microscopic train operation simulations with a macroscopic timetable optimization model within an iterative, cyclical feedback structure.
Fed fundamental running parameters derived from microscopic simulation into the macroscopic model to generate timetables, then calibrated results back through simulation.
Applied the integrated capacity evaluation framework to the Pyeongtaek–Osong four-track railway construction project.
Enabled the generation and compression of realistic operational schedules from preliminary service plans without requiring pre-existing operational timetables.
Demonstrated the practical viability of the iterative micro-macro simulation framework for evaluating track capacity expansions in planned rail corridors.

Implication

Simulation study demonstrates an integrated microscopic and macroscopic modeling framework for rail capacity assessment, indicating feasible timetable compression during infrastructure design.
