SELECTED ASPECTS OF THE CONCEPT OF OPERATING TRAIN TRAFFIC UNDER THE SUPERVISION OF THE ERTMS/ETCS L2 SYSTEM ON HIGH-SPEED LINES BASED ON SIMULATION STUDIES

High-speed railway lines require the establishment of separate rules and regulations for the design and operation of traffic relative to conventional lines. These lines require the use of advanced train protection systems, such as the ERTMS/ETCS Level 2. The functionality, configuration and design capabilities of the indicated system provide opportunities for its development, including its adaptation and performance improvements. The configuration parameters are variables defined for both on-board and trackside equipment and design rules. This article presents the results of simulation studies, which made it possible to study the influence of the set parameters on system performance. In doing so, this study provides an opportunity to establish design and configuration rules for selected aspects of the ETCS.
