Estimation of train dwell time at short stops based on track occupation event data

Li, D. (author), Daamen, W. (author), Goverde, R.M.P. (author)

Train dwell time is one of the most unpredictable components of railway operations mainly due to the varying volumes of alighting and boarding passengers. For reliable estimations of train running times and route conflicts on main lines it is however necessary to obtain accurate estimations of dwell times at the intermediate stops on the main...

Running time supplements: Energy-efficient train control versus robust timetables

Goverde, R.M.P. (author), Scheepmaker, G.M. (author)

Energy-efficient train operation is not yet included in the timetable design process in the Netherlands. Hence, running time supplements are not optimally distributed in the timetable. Therefore research has been conducted on the possibilities to better incorporate energy-efficient train operation into the railway timetable. This paper describes...

Automatic real-time control of railway traffic perturbations has recently received the attention of practitioners. The aim is to make use of mathematical algorithms to maintain the required service availability during unplanned disturbances to operations. In the literature many tools for real-time traffic control are proposed, but their effects...

Railway line capacity consumption of different railway signalling systems under scheduled and disturbed conditions

Goverde, R.M.P. (author), Corman, F. (author), D'Ariano, A. (author)

This paper evaluates the capacity consumption on a Dutch railway line both under scheduled and disturbed traffic conditions. For the scheduled condition the standard UIC compression method is used, while the computation of capacity consumption under disturbed conditions requires multiple simulation runs via a Monte Carlo simulation set up. For...

Rescheduling models for network-wide railway traffic management

Kecman, P. (author), Corman, F. (author), D'Ariano, A. (author), Goverde, R.M.P. (author)

In the last decades of railway operations research, microscopic models have been intensively studied to support traffic operators in managing their dispatching areas. However, those models result in long computation times for large and highly utilized networks. The problem of controlling country-wide traffic is still open since the coordination...

Yan, F. (author), Goverde, R.M.P. (author)

To satisfy the growing passenger transportation demands and improve the service quality n railway system, a more stable and robust timetable needs to be designed while considering highly utilized capacity. Acyclic timetable is extensively applied in large ailway networks. In order to acquire the quality of timetable, analytical timetable...

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

Goverde, R.M.P. (author)

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...

Robuust spoor met ERTMS

Goverde, R.M.P. (author)

Een systeem is robuust als het blijft presteren bij incorrecte invoer of onder bijzondere condities. Een spoorsysteem is dus robuust als het blijft functioneren bij afwijkende procestijden ten opzichte van de planning, bij afwijkende beschikbaarheid van de infrastructuur, of bij slechte weersomstandigheden. Een betrouwbaar en robuust...

Improving Punctuality and Transfer Reliability by Railway Timetable Optimization

Goverde, R.M.P. (author)

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...

Process mining approach for recovery of realized train paths and route conflict identification

Kecman, P. (author), Goverde, R.M.P. (author)

Data records from train describer systems are a valuable source of information for analyzing railway operations performance and assessing railway timetable quality. This paper presents a tool based on process mining event data records from the Dutch train describer system TROTS. The underlying algorithms automatically identify route conflicts...

A three-level framework for performance-based railway timetabling

Goverde, R.M.P. (author), Besinovic, N. (author), Binder, A. (author), Cacchiani, V. (author), Quaglietta, E. (author), Roberti, R. (author), Toth, P. (author)

The performance of railway operations depends highly on the quality of the railway timetable. In particular for dense railway networks it can be a challenge to obtain a stable robust conflict-free and energy-efficient timetable with acceptable infrastructure occupation and short travel times. This paper presents a performance-based railway...

Delay distributions in railway stations

Goverde, R.M.P. (author), Hansen, I.A. (author), Hooghiemstra, G. (author), Lopuhaa, H.P. (author)

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...

Optimizing public transport planning and operations using automatic vehicle location data: The Dutch example

Van Oort, N. (author), Sparing, D. (author), Brands, T. (author), Goverde, R.M.P. (author)

There is a growing pressure on urban public transport companies and authorities to improve efficiency, stemming from reduced budgets, political expectations and competition between operators. In order to find inefficiencies, bottlenecks and potentials in the public transport service, it is useful to learn from recorded operational data. We first...

A simulation-based optimization approach for the calibration of dynamic train speed profiles

Besinovic, N. (author), Quaglietta, E. (author), Goverde, R.M.P. (author)

Predictions of railway traffic are needed by planners and dispatchers for the design of robust timetables and real-time traffic management of perturbed conditions. These tasks can be effectively performed only when using train running time models which reliably describe actual speed profiles. To this purpose calibration of model parameters...

An Optimization Model for Simultaneous Periodic Timetable Generation and Stability Analysis

Sparing, D. (author), Goverde, R.M.P. (author), Hansen, I.A. (author)

We present an optimization model which is able to generate feasible periodic timetables for networks given the line structure and the requested line frequencies, taking into account infrastructure constraints and train overtake locations. As the model uses the minimum cycle time as the objective function, the stability of the timetable is also...

Identifying effective guaranteed connections in a multimodal public transport network

Sparing, D. (author), Goverde, R.M.P. (author)

Minimizing transfer waiting time is important in making public transport networks more attractive. A guaranteed transfer, with the departing vehicle waiting on moderately delayed arriving vehicles at a transfer node, is an effective way to reduce waiting times at transfers between low frequency public transport lines. This secondary train delay...

An online railway traffic prediction model

Kecman, P. (author), Goverde, R.M.P. (author)

Prediction of train positions in time and space is required for traffic control and passenger information. However, in practice only the last measured train delays are known and dispatchers must predict the arrival times of trains without adequate computer support. This paper presents a real-time tool for continuous online prediction of train...
