Dynamic Responsive Signal Control for Railway Junctions

车站和枢纽是铁路系统的重要组成部分，但它们也是铁路网络容量的主要制约因素。一些新技术，如欧洲铁路交通管理系统（ERTMS） 3级，已经被提议用于路口之间的轨道信号控制，但到目前为止，还没有创新的技术被提议用于路口和车站。在目前的系统中，信号控制人员手动控制信号，但他们需要随时考虑各种因素。有几个车站采用了自动路线设置系统，但运营复杂的主要车站仍然依赖于人员的手动控制，因为自动路线设置系统只解决列车之间可能出现的未来冲突，而不考虑其他因素，如运营和优化网络层面的列车运营。该项目的目的是通过加强对铁路枢纽的控制来提高铁路网络的容量。其目的是利用道路交通管理和控制应用中使用的技术，通过发展动态全面响应控制的概念，探索扩大铁路枢纽能力的方法。该项目还将调查其他运输行业所使用的技术，这些行业的业务是根据需求而定的，即飞机降落的机场业务、出租车业务和紧急车辆业务。拟议项目的主要目标是制定铁路枢纽和车站动态响应操作的框架，以及支持该框架的控制策略。特别是，我们将：-分析铁路枢纽和车站响应式操作的因素，以制定动态综合响应式操作的框架-制定支持动态响应式操作的控制策略和实施这些策略的算法。-以模拟方式研究新架构及策略的效果新架构及策略不涉及铺设额外的轨道，因此无须购买额外的土地及进行额外的土木工程。我们的新框架和战略可以成为提高能力的一种经济方式。此外，该框架和策略将减少服务中断后的恢复时间。这有助于培训运营公司和基础设施管理公司减少因服务中断而增加的运营成本。

Stations and junctions are vital elements of railway systems, but they are also a major constraint on network capacity. Several new technologies, such as the European Railway Traffic Management System (ERTMS) level 3, have been proposed for signal control of tracks between junctions, but as yet no innovative technology has been proposed for junctions and stations. In the current system, signal control officers manually control signals, but they need to consider various factors at every moment. Several stations have adopted the Automatic Route Setting (ARS) system, but major stations with complex operations still rely on manual control of officers because ARS only solves possible future conflicts between trains and does not consider other factors such as operations and optimisation of train operations at the network level.The purpose of this project is to increase the capacity of rail networks by enhancing the control of rail junctions. Its aim is to explore ways in which the capacity of railway junctions can be expanded by developing concepts of dynamic comprehensive responsive control, drawing on techniques used in road traffic management and control applications. The project will also investigate techniques used in other transport industries where the operation is demand-responsive, namely airport operation for landing aircrafts, taxi operation, and emergency vehicle operation.The main objective of the proposed project is to develop a framework for dynamic responsive operation at railway junctions and stations, and control strategies that support the framework. In particular, we will:- Analyse the factors in responsive operations at railway junctions and stations in order to develop a framework for dynamic comprehensive responsive operations - Develop control strategies that support dynamic responsive operations and an algorithm that implement these strategies. - Examine the effects of the new framework and the strategies by simulationThe new framework and strategies do not involve laying additional tracks, which requires the purchase of additional land and additional civil engineering work. Our new framework and strategies can be an economical way of increasing capacity. In addition, the framework and strategies will reduce the recovery time from service disruptions. This helps train operating companies and infrastructure management companies reduce the increase of operation costs caused by service disruptions.
