New Strategy to Optimize Flexible Time Arrangement in Railway Timetable

Abstract:

A new strategy to optimize reserve time arrangement——Curved Train Path (CTP) has been developed, and allowance is set by sections, this method decreases delay level, improves capacity utility and balances three parameters of timetable quality. In the aim of maximum passenger economic benefit, the principle to choose timetable variants under this strategy is determined. Finally, take a local passenger line for example, different timetable variants based on CTP strategy have been simulated and analyzed with Railsys® software. Average delay along the train path under different allowance percentage has been evaluated, and the optimal timetable variant has been confirmed.

Key words:allowance, flexible time, timetable quality, delay, simulation
