Station Timetable Homogenization Assessment in Urban Rail Transit Network

Heterogeneity is one of the key indicators to evaluate the quality of a rail transit timetable; it not only affects the station's capacity and operational processes, but also affects the continuation of rolling stock use and the efficiency of station equipment, network reliability, and the service level of passengers. First, this paper gives the arriving, departing, and whole timetable heterogeneity index based on the deviation of the actual interval and the average intervals in stations, and then gives an assessment of a model and solution method. Finally, taking Shanghai rail transit lines 3 and 4 as an example, the corresponding optimization recommendation is proposed by a different scheduling methodology.
