| Summary | Railway system train delays are affected by many factors, and one of the most important factors is insufficient line capacity, and knock-on delays (delay propagation) caused by the first delays, always interrupt railway operation. How to reduce the knock-on delays quickly is the most important issue to maintain timetable reliability and the high quality of the railway service. In order to clarify the impacts of these complicated factors and their interactions on knock-on delays, this research develops a comprehensive simulation model to deal with the related problems, and a rail section from Cidu to Shulin of the Taiwan railway system is selected for case study. Regression analysis is used to calibrate the relationships of the knock-on delay with the three key factors, which are train density, first delay and timetable recovery strategy based on the simulation results of the case study. The regression models indicate that the relationship between the knock-on delay and these three key factors conforms to an exponential function. It is expected that the results can be helpful to timetable scheduling, system reliability analysis and service quality improvement. |
