限速区段列车流特性及运行延误研究
Study on characteristics of traffic flow of trains and operational delay in speed-limited section
摘要
Abstract
By analyzing the operational characteristics of trains in speed-limited section, it proposes a cellular automaton model for train movements in the four-aspect fixed-block system. The operational properties and delay laws of traffic flow of mixed trains are investigated in this paper, and the reasons causing operational delay are also analyzed. The results show that when the passenger and freight trains operate on the same railway, the reasons which cause the delay are speed-limit and inhibiting effect of freight trains to passenger trains, and the delay time increases with the length grow of speed-limited section. The inhibiting effect decreases with the increasing of train departure interval, and once it is greater than a critical value, the main reason inducing train delay is only speed-limit of slowdown section. When the train depar-ture interval maintains a constant value, the average delay time of trains will form a“arch”with the increasing proportion of passenger and freight trains, and when the proportion ranges from 0.55~0.65, the average delay time reaches to maximum.关键词
