A consortium of Dutch researchers has investigated the reliability in the quality of travelling by private and public travel modes. In this paper, the reliability of travel times in public transport chains is examined. Until now, the only research in this field has been directed at trip reliability. A sample of 300 trips by public transport chains was used. These trips were operationalized for three different periods of the week (peak hour, off-peak, and during the weekend), according to the official timetables as published by the public transport companies. The distribution of arrival and departure times was used, specified for each public transport mode, to simulate disturbances of the travel times compared to official travel times as published by the public transport companies. Finally, a sensitivity analysis was used to study the impacts of different policy measures to improve travel times and the reliability in travel times by public transport chains.
