The development of China’s “eight vertical and eight horizontal” railway network has led to the transition of China’s railway from the “big construction” stage to the “big operation” stage. To improve the efficiency of railway transportation organization and meet the growing travel needs of the people, how to comprehensively consider the issues of train line planning optimization and timetable optimization has become a key factor. To this end, this paper first puts forward the simple algorithm of the train line planning optimization, that is, first determine the train running section, then calculate the number of trains and determine the stopping plan of each train. Then, taking the minimum total train travel time as the objective function, the optimization model of the high-speed railway timetable is constructed. The model adds train proportionality constraints to ensure the proportionality of the timetable with a small number of trains. Finally, taking the Rizhao-Qufu section of RLHSR as an example, the optimization research of the operation schedule and timetable is carried out. A total of 19 pairs of trains are running on the Rizhao-Qufu section of RLHSR, including 17 pairs from the Rizhao West-Qufu East section and 2 pairs from the Linyi north-Qufu East section. The total travel time of trains on the RLHSR is 2760 min.

摘要

The development of China’s “eight vertical and eight horizontal” railway network has led to the transition of China’s railway from the “big construction” stage to the “big operation” stage. To improve the efficiency of railway transportation organization and meet the growing travel needs of the people, how to comprehensively consider the issues of train line planning optimization and timetable optimization has become a key factor. To this end, this paper first puts forward the simple algorithm of the train line planning optimization, that is, first determine the train running section, then calculate the number of trains and determine the stopping plan of each train. Then, taking the minimum total train travel time as the objective function, the optimization model of the high-speed railway timetable is constructed. The model adds train proportionality constraints to ensure the proportionality of the timetable with a small number of trains. Finally, taking the Rizhao-Qufu section of RLHSR as an example, the optimization research of the operation schedule and timetable is carried out. A total of 19 pairs of trains are running on the Rizhao-Qufu section of RLHSR, including 17 pairs from the Rizhao West-Qufu East section and 2 pairs from the Linyi north-Qufu East section. The total travel time of trains on the RLHSR is 2760 min.
