Abstract

Level crossings are critical points in railway safety since most of the railway accidents in the world occur at level crossings. This issue is more critical in Türkiye when compared to European statistics. Even though in most cases, car drivers cause accidents at level crossings; the benefit of usage of safety-developed level crossing systems, to reduce the probability of accidents, is undeniable. To improve the safety characteristics of a level crossing system, certain crucial points must be identified. In addition, achievement of SIL 4 compliance reduces both random and systematic failures. In this study, id-LX, an independent level crossing system, is presented to provide a high safety protection system; Failure Modes and Effect Analysis and Fault Tree Analysis were performed respectively. This is a system based on SIL 4 certified PLC and software as a logic unit, including SIL 4 complaint modules for activating wayside equipment and for transmitting indication information to the logic unit. This fail-safe system is also capable in emergency situations to keep safe state. SIL 4 compliance, protection against common causes between level crossing equipment, a certified logic unit and a robust train driver warning signals are key advantages to reduce accident potential at level crossings. It has been proven that with the implementation of the proposed system, common safety targets in Türkiye can be significantly improved.

Abstract

Hemzemin geçitler, demiryolu emniyetinde kritik noktalar olup, dünyadaki demiryolu kazalarının çoğu hemzemin geçitlerde meydana gelmektedir. Bu konu Avrupa istatistiklerine kıyasla Türkiye’de daha kritiktir. Çoğu durumda karayolu araç sürücüleri hemzemin geçitlerde kazalara neden olsa da, kaza olasılığını azaltmak için emniyet açısından geliştirilmiş hemzemin geçit sistemleri kullanımının faydası yadsınamayacak kadar fazladır. Bir hemzemin geçit sisteminin emniyet özelliklerini geliştirmek için bazı önemli noktaların tanımlanması gerekir. Bunlara ek olarak, SIL 4 uyumluluğunun sağlanması hem rastgele hem de sistematik arızaları azaltır. Bu çalışmada, yüksek emniyetli koruma sistemi sağlamak amacıyla bağımsız bir hemzemin geçit sistemi olan id-LX, sunulmuş; sırasıyla Hata Türü ve Etkileri Analizi ile Hata Ağacı Analizi yapılmıştır. Bu sistem, yolboyu ekipmanlarını etkinleştirmek ve gösterge bilgilerini mantık ünitesine iletmek için SIL 4 uyumlu modülleri de dahil olmak üzere, SIL 4 sertifikalı PLC ve mantık ünitesi olarak yazılıma dayanan bir sistemdir. Bu arıza emniyetli sistem, acil durumlarda emniyetli durumu koruma kabiliyetine de sahiptir. SIL 4 uyumluluğu, hemzemin geçit ekipmanları arasındaki ortak nedenlere karşı koruma, sertifikalı bir mantık ünitesi ve sağlam bir makinist uyarı sinyalleri, hemzemin geçitlerde kaza potansiyelini azaltmak için önemli avantajlardır. Önerilen sistemin uygulamaya konması ile, Türkiye'deki yaygın emniyet hedeflerinin önemli ölçüde iyileştirilebileceği kanıtlanmıştır.
