A key challenge for railway transport is to guarantee an attractive overall offer that is flexible in adapting capacity to meet both short-term variations and long-term trends in travel demand. In the Netherlands and many other European countries, passenger trains operate a fixed line plan with a regular interval throughout the day for each day of the week. However, there is an increasing interest in more flexible timetables that are better aligned with distinctive passenger flow patterns over the day or between days. For instance, commuter and leisure travels differ often in destination like business districts versus city centres. The COVID-19 pandemic clearly demonstrates how passenger demand dynamically evolves depending on government restrictions. Among the long-term behavioural effects of this pandemic, it is expected that more people will continue working from home with a preference for certain days.
In this PhD research you will be developing mathematical models to compute railway timetables that are flexible to variations in travel demand patterns. You will analyse passenger travel data to derive structural variations in passenger routes and departure times over the week. For the long term, you will apply stated preference methods to predict structural variations in future passenger behaviour. From the identified distinctive demand patterns you will derive homogeneous timetable periods with train service variations that may vary from small variations of a basic hour pattern to large changes in the line plan in certain areas and periods. Ultimately, you will develop a flexible railway timetable optimization problem to compute conflict-free multi-periodic railway timetables with service variations over homogeneous periods. This optimization problem will integrate elements from line planning, railway timetabling and passenger routing. Finally, you will solve flexible timetable problems for real-world cases from Netherlands railways.
This PhD project is a collaboration between the Department of Transport & Planning (T&P) of Delft University of Technology, and the Department Performance management & Innovation (PI) of Netherlands Railways (NS). You will be part of both the Digital Rail Traffic Lab (DRTLab) and the Smart Public Transport Lab (SPTL) at T&P, and also work in the Department PI at NS for one day per week. T&P aims at top-level fundamental research that contributes to a more efficient and robust design and reliable operation of transport systems. T&P is composed of 11 research labs addressing various transport challenges. The DRTLab develops innovative models and methods for railway transport planning, railway traffic management and train control to improve overall railway transport system performance. The SPTL develops new solutions and methods for public transport planning, operations and management
