在本文中,我们构建一种新的战略性规划框架,即在不考虑列车时刻表的情况下计算铁路基础设施占用时间和路网能力耗费。并且,文中还介绍了采用该框架所建立的模型,在此模型下生成了不同的行车顺序并对其进行评估,实现不依赖于时刻表来进... 在本文中,我们构建一种新的战略性规划框架,即在不考虑列车时刻表的情况下计算铁路基础设施占用时间和路网能力耗费。并且,文中还介绍了采用该框架所建立的模型,在此模型下生成了不同的行车顺序并对其进行评估,实现不依赖于时刻表来进行相关计算,并通过模拟列车延误的随机性得到了能力耗费率。以一个考虑了四种不同基础设施使用情况的路网为例,对该模型进行了测试,测试结果表明在很少输入的情况下均能高效地得到基础设施占用时间和能力耗费率。该案例说明了本模型具有根据基础设施使用情况的变化来量化能力增益的功能,可用于增加行车量或提高铁路系统的鲁棒性。 展开更多

The objective is to provide railway undertakings with access to the railway network on equal terms. The main problem is determining the infrastructure capacity. A variety of methodologies are used across Europe for the capacity estimation of railway infrastructure. This diversity has forced railway infrastructure managers to seek a new, common methodology. The UIC methodology is an easy way to calculate the capacity consumption. However, there the possibility to expound this methodology in different ways, which can result in different capacity consumptions. There isan advantage to improve this methodology and to set a clear and unified method of occupation time estimation. The fundamental improvement to UIC methodology is the definition of the occupation time by the trains. This paper gives a description of Slovak and UIC methodologies as a basis for a newly developed approach. The new way of estimation of the capacity consumption (occupation time) is based on a graphic approach. The new methodology concerns the estimation of the infrastructure occupation time and is a conceptual framework developed by the authors for an easier evaluation of occupation time in train traffic diagrams. The new methodology makes the UIC methodology more usable and enables more exact results to be obtained from infrastructure capacity examination. 展开更多
