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，已被提议用于交叉口之间轨道的信号控制，但尚未提出用于交叉口和车站的创新技术。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。目前已有多个车站采用了自动进路设定（ARS）系统，但操作复杂的主要车站仍依赖于人员的人工控制，因为ARS系统只解决了列车之间未来可能发生的冲突，而没有考虑其他因素，如网络层面的运营和列车运营优化。本项目的目的是通过加强对铁路枢纽的控制来增加铁路网络的容量。其目的是探讨如何通过发展动态综合响应控制的概念，利用道路交通管理和控制应用中使用的技术，扩大铁路枢纽的能力。该项目亦会研究其他运输行业所采用的技术，包括飞机降落的机场运作、的士运作及紧急车辆运作等。建议项目的主要目的，是为铁路交汇处及车站制订一个动态回应运作的架构，以及支援该架构的控制策略。特别是，我们将：-分析在铁路枢纽和车站响应操作的因素，以制定一个框架，动态全面响应操作-开发控制策略，支持动态响应操作和算法，实现这些战略。- 通过模拟研究新框架和策略的效果新框架和策略不涉及铺设额外的轨道，这需要购买额外的土地和额外的土木工程。我们的新框架和战略可以成为增加能力的经济方式。此外，该框架和策略将减少服务中断的恢复时间。这有助于列车运营公司和基础设施管理公司减少因服务中断而导致的运营成本增加。

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.
