Energy-efficient Timetable Creation Method by Adjusting Arrival and Departure Times Considering Passenger Convenience

Abstract

We developed a method for creating energy-efficient timetables by reducing powering energy consumption and making effective use of regenerative energy, through mathematical optimization. This approach incorporates passenger convenience ensuring that the total traveling time from the starting station to the terminal station of each train remains consistent with the original timetable. This paper describes the details of the method for creating energy-efficient timetables and reports the results from a case study using real-world line data. In this case study, energy-efficient improvements of 7.4% and 4.9% were achieved when auxiliary power is set according to the ambient temperatures equivalent to 15℃ and 30℃ respectively.
