Elimination of disadvantageous railway overtaking scenarios utilizing a fuzzy-logic driven performance indicator

Abstract

As railway traffic continues to grow, especially in suburban areas, it becomes increasingly important to both expand capacity and improve its utilization. The most promising strategy is to enhance the efficiency of capacity usage, primarily through the implementation of advanced operational support systems that assist traffic controllers in making faster and more accurate decisions during traffic conflicts. In densely populated urban areas, slower trains are frequently overtaken by faster ones. The utilization of performance indicators has the potential to facilitate the analysis and prevention of errors, as well as the resolution of conflicts in such circumstances. This paper introduces a novel methodology to facilitate the evaluation of disparate traffic simulation scenarios. This fuzzy logic-driven methodology constitutes a pivotal step towards ensuring collision-free operation.
