    Assessing disruption management strategies in rail-bound urban public transport from a passenger perspective

    This paper provides a framework for generating and assessing alternatives
    in case of disruptions in rail-bound urban public transport systems,. The proposed
    framework considers the passenger perspective as well as the operator perspective,
    for the often-used measures of detouring and short-turning. An application of the
    framework demonstrates that currently used disruption management protocols often
    do not lead to the optimal solution from the passenger perspective. Furthermore, the
    optimal choice between alternatives from passenger perspective shows to be
    dependent on the passenger flows.

    Assessing and improving operational strategies for the benefit of passengers in rail-bound urban transport systems

    Unplanned disruptions in transit can have consequent impacts on passengers. The more inconvenienced passengers are, the more likely operators will be negatively impacted. Yet so far, operators and researchers have addressed the rescheduling problem during disruptions mainly with a supply-side focus – timetable, crews and vehicles – and not with a passenger perspective. Urban rail transit particularly lacks insights in terms of passenger- focused rescheduling. Being able to assess the inconvenience experienced by passengers during disruptions compared with what they normally experience, and being able to compare how different rescheduling strategies affect them are therefore two major challenges.

    The framework developed in this study precisely aims at tackling 8 these challenges. A case study of the metro of Rotterdam is used to test the framework developed in this paper. Alternative strategies are developed focusing on the incident phase (from the beginning of the incident until its cause is resolved). The application of the framework reveals that a regularity-focused rescheduling strategy would be beneficial for high-frequency service users. Realistically, yearly savings could amount to around €900,000 in terms of societal passenger costs for the operator in the Rotterdam area alone. However, the omnipresence of the punctuality paradigm, through which most operators plan and analyze operations, makes the implementation of passenger-focused strategies a challenging task for traffic controllers. The results of the study are valuable for transit operators worldwide and the framework can provide insights to decision-makers on the performance of different strategies, bringing to light trade-offs between supply and passenger sides during disruptions.
