Abstract

In recent years, some innovations have appeared in the operation of metro system to save energy consumption and speed up trains. Compared with the standard stop mode, in which a train stops at every station, express/local stop mode can lead to lower energy consumption and less travel time. This paper aims to find the relationship among energy consumption, travel time and timetables, and then obtain a more optimized solution via adjusting timetables. After analyzing the characteristics of express/local stop mode, we linearly formulate energy consumption and passenger travel time, and propose a bi-objective programming model to better understand the relationship between lowering energy consumption and reducing travel time. Taking Beijing Metro Line 6 as a numerical example, we compare the express/local mode and standard stop mode both in total travel time and energy consumption, illustrating the applicability of express/local mode.
