abstract

In order to keep certain level of train punctuality and flexibility of adjustment in practical operation phase, allowance which normally is set proportionally is added to the minimum running and dwell time. This paper develops a new strategy that through changing allowance arrangement to optimize timetable quality by using non-proportional distributed method–curving train path (CTP). With Railsys® as simulation tool, results shows that CTP is quite optimal to decrease delay and delay transfer, to spare more room for train path while the travel time remains constant, and timetable quality is improved to a new balance level.
