Abstract

Railway level crossings (RLCs) in Poland are classified according to their protection systems. Category D, which is a form of passive RLC, aims to ensure safe and efficient operation. Surveying is essential to prepare and control the geometry of the visibility triangles used at RLCs. This article presents a new approach to monitoring the geometry of visibility triangles of RLCs using an electronic total station and a magnetic measuring square (MMS). Its main assumptions are presented together with the application of the innovative measuring instruments. Visibility is demonstrated taking into account the angles of intersection of the road axis with the track axis of the railway line and additional attributes related to the analysis and evaluation of general visibility conditions. The research highlights controversies that have received special attention against the background of the safety status of railway level crossings. As a case study, the RLC located on a single-track railway line in Poland is examined. The final section presents applications of the results obtained according to the proposed methodology. It is shown that the proposed approach is practical and effective. In addition to surveyors, the survey methodology can be used by road and rail traffic engineers and policy makers to further improve traffic safety at RLCs. This is an important global research task.

摘要

波兰的铁路平交道口(RLCs)根据其保护系统进行分类。D类作为被动式铁路平交道口的一种形式,旨在确保安全高效运行。测量对于准备和控制铁路平交道口使用的视距三角形的几何形状至关重要。本文介绍了一种使用电子全站仪和磁测角器(MMS)监测铁路平交道口视距三角形几何形状的新方法。阐述了其主要假设以及创新测量仪器的应用。考虑到道路轴线与铁路线路轨道轴线的交角以及与一般视距条件分析和评估相关的其他属性,展示了视距情况。该研究突出了在铁路平交道口安全状况背景下受到特别关注的争议问题。作为案例研究,对波兰一条单轨铁路线上的铁路平交道口进行了考察。最后一部分介绍了根据所提出方法获得的结果的应用。结果表明,所提出的方法切实可行且有效。除测量员外,道路和铁路交通工程师以及政策制定者也可使用该测量方法,以进一步提高铁路平交道口的交通安全。这是一项重要的全球性研究任务。
