随着英国和其他地方的铁路交通水平的增加，对能力提供/利用与服务质量之间的权衡的更好理解变得越来越重要，因为基础设施管理者和铁路企业寻求在保持服务可靠性和准时性的同时最大化能力提供。对于形成铁路网络节点和容量瓶颈的车站和枢纽来说尤其如此，因为它们的能力利用率和性能之间的关系不如它们的中间环节那么好理解。在为OCCASION项目进行了节点容量利用指数的计算工作，并将这些技术应用于英国轨道通行收费的容量收费要素的重新校准之后，DITTO铁路系统项目的一个目标是进一步调查容量利用与性能之间的关系，如在火车站和路口的拥堵相关的反应延迟水平所示。选定站点的历史时间表和延迟数据已用于调查这些关系，这些关系采用预期的形式，往往表明站点的最大容量利用率低于它们之间的联系。目前正在开展进一步开发这些数据集和关系的工作，并确定适当的能力利用上限。(C) 2017 Elsevier Ltd.版权所有。
As railway traffic levels increase in Britain and elsewhere, improved understanding of the trade-offs between capacity provision/utilisation and service quality is increasingly important, as Infrastructure Managers and Railway Undertakings seek to maximise capacity provision while maintaining service reliability and punctuality. This is particularly true of the stations and junctions forming the nodes and capacity bottlenecks of railway networks, for which the relationships between capacity utilisation and performance are less well understood than for their intermediate links. Following work undertaken for the OCCASION project on the calculation of nodal Capacity Utilisation Indices, and on the application of these techniques to the recalibration of the Capacity Charge element of the Track Access Charges in Britain, one objective of the DITTO Rail Systems project is the further investigation of the relationship(s) between capacity utilisation and performance, as indicated by congestion-related reactionary delay levels at railway stations and junctions. Historic timetable and delay data for selected stations have been used to investigate these relationships, which take the expected form and tend to suggest lower maximum capacity utilisation levels for stations than for the links between them. Work is ongoing to develop these datasets and relationships further, and to identify suitable capacity utilisation upper limits. (C) 2017 Elsevier Ltd. All rights reserved.
