Application of Assurance Technology to Railway Signalling for Smooth Migration

Abstract

Assurance technology is known as a technology for replacing a system without stopping it under various circumstances. This paper discusses the application of assurance technology to railway signalling for smooth migration.

East Japan Railway Company applied assurance technology to the digital automatic train control (D-ATC) system introduced to operate the most crowded lines in the Tokyo metropolitan area. It was not only able to contribute to accelerating construction and improving the reliability of D-ATC, but also effective in enhancing the functionality of railway signalling which directly relates to railway business.
