RAPS, radio propagation simulator for CBTC system [PDF]

WIT Transactions on The Built Environment, 2012
One cost effective solution for traffic control and signaling of monorails and metro rail transit is a communication based train control system (CBTC). Radio transmission is one of the most effective CBTC subsystems. It can increase transportation capacity by moving a block control method with less trackside equipment.

Study on the mechanism of railway vehicle wheelset angular velocity change on curved tracks

Nihon Kikai Gakkai ronbunshu
The moving block system provided by CBTC increases train operation frequency and improves facilities management efficiency compared to the fixed block system. Trains controlled by CBTC need to have onboard functions to estimate their locations.

Autonomous Train Control System Principle: Fully Train‐Centric Route Generation and Track Resource Management

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
This study proposes a principle for an autonomous train control system (ATCS) where trains manage track resources, generate routes, and control trackside objects without relying on wayside controllers. Using Super Balise Groups (SBG) and directed graphs, the system simplifies route generation through factorization and composition, while a new braking ...

Safety monitor for train‐centric CBTC system [PDF]

IET Intelligent Transport Systems, 2018
Train‐centric communications‐based train control (TcCBTC) system is a new solution for urban transit signalling. Compared to traditional train control systems, the on‐board equipment is becoming more powerful and more complex. Due to its safety‐critical nature, specialised technologies must be adopted to guarantee the safety of the system.
