Safety distance control approach in moving block signaling systems

Abstract

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.
