摘要
提出一种优化弹性时间布置的新策略--弯曲列车运行线(curved train path,CTP),将附加时间分段设置,从而降低了延误水平,提高了能力利用率,使运行图质量三要素达到了新的平衡.以乘客经济效益最大为目标,建立了该策略实际应用中的运行图方案比选原则.最后以德国某市域线为例,基于CTP策略,运用Railsys(软件对不同运行图方案进行仿真分析,得出不同附加时间比例下的最优运行图方案.
Curved train path (CTP), a new strategy to optimize reserve time arrangement is developed, and allowance is set by sections. As a result, delay level decreases, the capacity utility is improved and the three parameters of timetable quality are balanced. With the aim to maximize the passenger economic benefit, the principle to choose timetable variants under this strategy is determined. Different timetable variants based on CTP strategy are simulated and analyzed with Railsys~ software by taking a German local passenger line for example. Average delay along the train path at different allowance percentages is evaluated, and the optimal timetable variant is determined.
