| Abstract: | The capacity of many railway networks and corridors in Europe is highly utilized, but ’planning norms’ such as headways and buffer times in the timetable are already optimized given the available infrastructure [1]. Thus, while maintaining high punctuality, planning norms in busy networks can only be further decreased by implementing new technologies, such as Driver Controlled Operation (DCO), European Rail Traffic Management System (ERTMS), Automatic Train Operation (ATO) and Traffic Management System (TMS). For each of these technologies, investments are necessary, which would be too expensive to implement directly on a national level. Furthermore, since the technologies are relatively new, it is desired to first investigate the effects of the technologies on a small number of corridors before implementing them nationally. Consequently, we find the need for a tool that can assess the implementation of new technologies on different corridors and rolling stock and their effect on the timetable. To this end, we propose a novel railway timetable optimization model that extends the Periodic Event Scheduling Problem (PESP)[2][3], by allowing the implementation of planning norm decreasing technologies under a budget constraint. Specifically, the model can choose what technologies to implement (DCO, ERTMS, ATO, TMS) on what corridors and train series such that the optimized timetable benefits the most. The model is tested on the Dutch national railway network and smaller sub-sections of it at varying input parameters. Numerical results show that the model can be solved efficiently for medium-sized instances and is able to use the available budget to implement planning norm decreasing technologies on specific corridors and train series. The proposed extended PESP-model can thus be used as a decision support tool for railway and infrastructure operators to determine which technologies should be implemented on which locations in a railway network. |
