Guideway database design in CBTC system simulation

Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011
This Paper introduced the GD (guideway database) design in CBTC (Communications-Based Train Control) system simulation in the scopes of data definition, data input, data parsing and data optimization. Based on directed graph, a standard mathematical topology representation, any location and physical equipment can be defined as a unique vector, such as

A Game Framework to Secure Control of CBTC Systems

2020
To meet the growing railway-transportation demand, researchers have designed a new train control system, communication-based train control (CBTC) system, to maximize the ability of train lines by reducing the headway of each train. However, wireless communications expose the CBTC system to new security threats.

Study on Modeling and Verification of CBTC Interlocking System

5th IET International Conference on Wireless, Mobile and Multimedia Networks (ICWMMN 2013), 2013
In CBTC (Communications Based Train Control) system, interlocking is considered to be one of the most fundamental system which features in logic complexity and high safety demand. Traditionally, the development and verification of interlocking system is entirely a manual process which relies too much on designers' experience and some corner-case bugs ...
