Abstract [en]

Valuations for various attributes of the transport supply are key parameters in travel demand forecast models and cost-benefit analyses. In the case of interregional rail travel, such attributes are mostly travel time, departure/ arrival time, and comfort/service levels. Although the valuations for travel time savings and comfort levels are well documented, literature concerning how much passengers are willing to pay to obtain the departure/arrival time that best suits their needs remains scarce. We present in this paper a new study that estimates passenger valuations for reduction of departure time displacement (also called schedule delay) through common adaptation of the scheduling model. Our goal is twofold: first, better understand how travel scheduling is influenced by socioeconomic backgrounds and trip characteristics; second, provide detailed figures that can be used to improve travel demand forecasts and cost-benefit analyses. To achieve this, we conducted a stated preference survey on several Swedish rail routes and determined the valuations for departure time scheduling as willingness to pay and time multipliers. The figures obtained show that departure time flexibility greatly depends on trip characteristics and travellers? socio-economic background. In addition, the comparison of our figures with previous literature highlights the need to establish a standardised method to measure and use these valuations. Finally, we succeeded in providing valuations that can be used with care as approximations in demand modelling and cost benefit analyses in the context of interregional rail travel.

Abstract [en]

In order to improve current rail timetabling processes, the suitability of train departure times for passengers should be included in timetable assessment. To achieve this, one possibility is to calculate the change in consumer and producer surplus (i.e., the economic welfare) resulting from departure time shifts in rail timetables. However, existing methods for this calculation are quite limited. To fill this gap, we propose a new method in the current paper. This method enables comparing most scenarios involved in interregional rail timetabling in terms of economic welfare. To this end, our method takes advantage of schedule-based models that allow assessing the impact of departure time shifts on the demand and valuation of each possible route using the timetable. As a proof of concept, we illustrate this method on a case study on the busiest Swedish interregional line. This case study shows the potential of the method to deliver detailed calculations with analysis of equity effects. To conclude, the method presented in this paper improves on the current literature, and it can be used to improve timetable optimisation algorithms or to better resolve conflicts between train path requests.
