Safety distance control approach in moving block signaling systems

Öz

As technology progresses in recent years, the advances in transportation continue rapidly. Some of these advances are seen in the railway industry. Especially the innovations in the railway interlocking system make this industry more preferable. One of these innovations is moving block signaling. In an urban rail transport system, moving block signaling has gradually started to replace the fixed block signaling with the development of driverless and communication-based control systems. In this study, an approach has been proposed for moving block signaling. The movement situations between the stations have been shown, by determining a reference speed profile and the relationship between the locations for the following railway vehicles have been evaluated by simulations obtained by MATLAB/SimulinkTM.

Hareketli blok sinyalizasyon sistemlerinde emniyet mesafesi kontrolü yaklaşımı

Öz

Son yıllarda teknoloji ilerledikçe, ulaşım sektöründeki ilerleyiş de hızla devam etmektedir. Bu ilerlemelerden bazıları da demiryolu endüstrisinde görülmektedir. Özellikle demiryolu anklaşman sisteminde ortaya çıkan yenilikler bu endüstriyi daha tercih edilir hale getirmektedir. Bu yeniliklerden birisi, hareketli blok sinyalizasyonudur. Şehirlerdeki hafif raylı ulaşım sistemlerinde hareketli blok sinyalizasyonu, sürücüsüz ve haberleşme tabanlı kontrol sistemlerinin gelişmesiyle, yavaş yavaş sabit bloklu sinyalizasyonun yerine geçmeye başlamıştır. Bu çalışmada da, hareketli blok sinyalizasyonu için bir yaklaşım önerilmiştir. Bir referans hız değeri belirlenerek, istasyonlar arasındaki hareket durumları gösterilmiş ve birbirlerini takip eden demiryolu araçları için konumlar arasındaki ilişki değerlendirilmiştir.
