Goverde, R.M.P. (author)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...conference paper 1998

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...conference paper 1999

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...conference paper 1999

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...conference paper 2001

Goverde, R.M.P. (author), Hansen, I.A. (author)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...conference paper 2001

Goverde, R.M.P. (author), Heidergott, B. (author), Merlet, G. (author)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...conference paper 2010

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...conference paper 2012

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...conference paper 2012

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.

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...conference paper 2012

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.

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

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...conference paper 2013

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.

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...conference paper 2013
