Variable Approach Locking Method for Improving Station Passing Capacity
摘要
Abstract
Approach locking is a way to ensure railway operation safety.For the trains with different speed levels,the existing approach locking methods uniformly set the approach section length as a fixed value,which ignores the differences in the train control levels,speeds,and braking performance to cause excessive occupation of station resources and affect the station passing capacity.Based on the calculation methods of approach locking sections and the relationship between trigger time for automatic routing and approach sections,this paper proposed a variable approach locking method by considering train traction calculation and routing handling process of high speed railway as key factors.This method added necessary hardware equipment to make the station set the approach locking length and trigger routing handling time according to the train status information.Simulation experiments conducted by taking a station as an example show that the proposed method can improve the station passing capacity,and increase the passing capacity of the throat area by up to 85 trains and the passing capacity of the arrival-departure track by up to 32 trains.关键词
