Research on Urban Railway Knowledge-Based CBTC System
2011 Third Pacific-Asia Conference on Circuits, Communications and System (PACCS), 2011Automatic train control system (ATC) is a safety related system in urban rail transportation. As the latest ATC technology, the communication based train control (CBTC) system is a large-scale knowledge based system. The architecture, the trackside control level and the onboard control level of CBTC are discussed.

Modeling the CBTC Railway System of Siemens with ScOLa
International Journal of Intelligent Transportation Systems Research, 2017Considering their increasing complexity, industrial systems are, in general, specified in a natural language. In railway systems, the design phase results an ambiguous and laborious system specification. The objective of this paper is to present ScOLa, a formal modeling language based on scenarios and built for railway system specifications.
