Computing delay resistant railway timetables
WebSep 9, 2024 · The cost of scheduled in-vehicle travel time and mean delay was reduced by 5% on average, representing a large improvement for a highly utilized railway line. Furthermore, a separate scaling experiment indicates that the approach can also be suitable for larger problems. WebAutomatic Train Systems (ATSs) have attracted much attention in recent years. A reliable ATS can reschedule timetables adaptively and rapidly whenever a possible disturbance breaks the original timetable. Most …

WebJun 11, 2024 · However, it is obvious that such a solution is unacceptable for passengers. The art of delay resistant timetabling hence is to achieve a certain level of robustness by a minimum increase in nominal travel times. Recently, theoretical studies have been directed towards the problem of designing delay resistant timetables [14,21] . WebMay 27, 2024 · According to the accepted criteria for evaluating disruptions in the time context, delays greater than or equal to 5 min are taken into account [ 28 ]. Depending on the location of trains in the timetable, the system will be more or less vulnerable in context of delay propagation.
