基于换乘最优的城市圈城际铁路运行图研究

Optimal Transfer of Intercity Railway Train Diagram

城市圈城际铁路是中国铁路未来发展的重点之一.在城际铁路间换乘所需换乘等待时间的长短是影响乘客满意度的重要因素.因此,在编制城际铁路列车运行图的过程中,应设法减少乘客的换乘等待时间并尽量不使乘客错过换乘.本文对具体换乘过程进行分类并详细分析,提出列车延迟时间和乘客换乘走行时间的概率分布,并据此计算乘客换乘等待时间.在周期事件规划问题(PESP)相关理论的基础上,本文提出基于换乘最优的城际铁路周期运行图编制模型,并以某城市圈的城际铁路网为例,验证该模型的可行性.结果表明,根据该模型编制的列车运行图可以显著地减少乘客换乘等待时间,从而提高乘客满意度.

The intercity railway in urban circles is one of the key parts of China＇s railway development in the future. The transfer waiting time of intercity railway transfer is an important factor influencing the satisfaction of passengers. Therefore, when establishing the intercity railway train diagram, reducing the transfer waiting time of passengers and trying not to make passengers to miss their transfer should be taken into consideration. This paper makes a concrete analysis of the transfer process,puts forward probability distributions of the train delay time and passenger transfer walking time and calculates the transfer waiting time. Based on the periodic event schedule problem model（PESP）, a model based on optimal transfer is put forward and applied to a case study. The result shows that the train diagram developed by the model can effectively reduce the transfer waiting time, thereby improving the satisfaction of passengers.
