Simulation Analysis of Train Rescheduling Strategies in Railway Operation of Passenger Dedicated Line

It took various factors including train class,delay status and remained distance into account to analyze the possible rescheduling strategies in train operation of passenger dedicated line under the operation mode with both high-speed and middle-speed trains.On this basis,the process of train rescheduling was simulated according to the behavior of dispatchers under various situations that different types of delay occurred and different strategies were applied.The analysis results of quantity of delayed trains and delay time showed that: 1) The high-speed trains had greater anti-turbulence ability.The better result could be achieved if all trains ran by the existing order.2) If the middle-speed trains were prohibited to influence the high-speed trains,they would have poor anti-turbulence ability and the trains with longer remained distance and the punctual trains should have greater priority.On the contrary,their anti-turbulence ability would increase remarkably.At the same time,the influence on high-speed trains would be quit little if only the time that high-speed trains could be postponed was less than headway time between them.
