Guideway database design in CBTC system simulation
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011This 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

The channel emulator for CBTC wireless communication system
2010 7th International Symposium on Communication Systems, Networks & Digital Signal Processing (CSNDSP 2010), 2010A channel emulator working at 2.4 GHz ISM band related to tunnel environments for testing communication based train control (CBTC) wireless system is introduced. Based on three mechanisms, path loss, multi-path fading and Doppler frequency shift, the multi-port channel matrix is adopted to construct a multi-input and multi-output channel environment ...

Secure Communications Based Train Control (CBTC) Operations
2009Communications Based Train Control (CBTC) provides positive train separation, over speed protection, and protection for roadway workers. Current system designs do not include trust management systems to provide support for security, rendering CBTC communications vulnerable to malactors.

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.

CBTC are modern railway signaling systems used in urban railway lines for light rail (e.g., tranvia), heavy rail (e.g., metro) and APM (Automated People Mover, e.g., Airport metros). Sometimes, they can be deployed also on commuter lines (rails going to suburban areas, e.g., S-Bhan).

Design and Implementation of Data Generation for CBTC
2012For the low efficiency of data generation in CBTC(Communication Based Train Control), this paper proposes a data generation method based on ObjectARX. On the basis of CAD graph data structure, and the data elements and data structure in CBTC, we design and realize the method of lane data generation for CBTC by means of C# program language and ObjectARX

The New 4G Pilot for CBTC [Transportation Systems]
IEEE Vehicular Technology Magazine, 2015On 6 August 2014, Alstom and Huawei announced a long-term evolution (LTE) fourth-generation (4G) pilot for the metro market to demonstrate the performance of a multiservice broadband radio network for communications-based train control (CBTC). Alstom has been working on LTE since the technology has been available from the telecom industry.
