Data driven improvements in public transport: The Dutch example

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

Due to reduced budgets, higher political expectations and increasing competition between operators, there is growing pressure on public transport companies and authorities to improve their operational efficiency. It is thus of utter importance for them to be able to identify inefficiencies, bottlenecks and potentials in their public transport...

Optimal rerouting of short-turning trains during track obstructions

Ghaemi, N. (author), Goverde, R.M.P. (author), Cats, O. (author)

Railway trafic controllers have only limited decision support to deal with disruptions. The aim of this research is to provide an algorithm to compute conflict-free routes for trains that cannot continue their planned operation due to a track obstruction. In case of complete blockage, trains need to short-turn at the closest possible station to...

Predictive modelling of running and dwell times in railway traffic

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

Accurate estimation of running and dwell times is important for all levels of planning and control of railway traffic. The availability of historical track occupation data with a high degree of granularity inspired a data-driven approach for estimating these process times. In this paper we present and compare the accuracy of several approaches...

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...

Optimal Management of Railway Perturbations by Means of an Integrated Support System for Real-Time Traffic Control

Quaglietta, E. (author), Goverde, R.M.P. (author), Albrecht, T. (author), Jaekel, B. (author), Marliere, G. (author), Pellegrini, P. (author), Rodriguez, J. (author), Dollevoet, T. (author), Ambrogio, B. (author), Carcasole, D. (author), Giaroli, M. (author), Nicholson, G. (author)

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...

Stability and robustness analysis of acyclic timetable

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...

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...

Review of railway disruption management practice and literature

Ghaemi, N. (author), Goverde, R.M.P. (author)

This paper investigates the challenges of railway traffic controllers in dealing with big disruptions and the kind of support tools that could help to improve their task in terms of performance and lead time. The disruption handling process can be partitioned into three phases according to the bathtub model and to each phase the essential...

Integrated Decision Support Tools for Disruption Management

Besinovic, N. (author), Cacchiani, V. (author), Dollevoet, T. (author), Goverde, R.M.P. (author), Huisman, D. (author), Kidd, M.P. (author), Kroon, L.G. (author), Quaglietta, E. (author), Rodriguez, J. (author), Toth, P. (author), Veelenturf, L. (author), Wagenaar, J. (author)

During railway operations unexpected events can require railway operators and infrastructure managers to adjust their schedules. In this research we investigate the disruption management process. More specifically, we come up with an architecture and algorithmic framework which railway operators could use for decision support during disruptions....

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...

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...

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...

Stability of railway dispatching solutions under a stochastic and dynamic environment

Quaglietta, E. (author), Corman, F. (author), Goverde, R.M.P. (author)

In the last decade simulation models and optimization environments have been developed that are able to address the complexity of real-time railway dispatching. Nevertheless, actual implementations of these systems in practice are scarce. Essential for implementation of an advanced dispatching system is the trust of traffic controllers into a...
