Railway Timetable Stability Analysis Using Stochastic Max-Plus Linear Systems

Stability and robustness of a railway timetable are essential properties for punctual and reliable operations. Timetable performance evaluation is therefore an important aspect in the timetable design process. In particular, the stability and recoverability properties of a timetable with respect to daily process time variations must be well...

Stabiliteitsanalyse van spoorwegdienstregelingen

De capaciteitsverdeling van het spoor aan de diverse vervoerders gebeurt via basisuurpatronen (BUP’s) zoals vastgelegd in de Netverklaring door ProRail. De TU Delft heeft de analysetool PETER ontwikkeld waarmee de stabiliteit van basisuurpatronen op netwerkniveau kunnen worden geanalyseerd op een transparante, non-discriminatoire, controleerbare...

Stability analysis of periodic railway timetables; A max-plus algebra approach

Delay propagation and process management at railway stations

Process operators at large railway stations have the difficult task to secure a fluent train traffic flow while minimizing deviations from established timetables. Variation in actual train departure times is inevitable due to many circumstances such as arrival delays and fluctuations in alighting and boarding time, even if some buffer time is...

Delay distributions in railway stations

The estimation of the precise arrival and departure times of trains at stations is done by means of a software tool that extracts the occupation and clearance times of each train per track section of the Dutch Railways‘ network. The software tool was applied to the whole automatically collected set of signal data of the area of Eindhoven during...

Improving Punctuality and Transfer Reliability by Railway Timetable Optimization

The Dutch railway network is operated close to capacity with the current safety system. This leaves little space for control by process operators by which a delayed train can cause severe delay propagation. The NS currently invest a large amount in punctuality improvement of the railway operations. This paper shows how the effect of delays can...

Optimal Train Dispatching at Railway Stations: A Discrete Event Dynamic System Approach

Reliability of transfers in a transportation network largely influences the level of service of trip chains. Especially in low-frequency service networks like (long-distance) railway networks. Running and dwell times are typically subject to random variations resulting in arrival delays during operation. If a scheduled transfer connection is...

Synchronization Control of Scheduled Train Services to Minimize Passenger Waiting Times

During operation a transportation service may wait on delayed feeder services to secure scheduled transfers. For low-frequent connecting services this has a major positive impact on the transfer waiting times. However, the resulting synchronization control time of the connecting service also affects the waiting times of originating and through...
