Driverless CBTC – specific requirements for CBTC systems to overcome operation challenges [PDF]
WIT Transactions on The Built Environment, Vol 88, 2006 This paper describes how reliable driverless operation requires specific features implemented at system and subsystem levels of the train control system. Communications-Based Train Control (CBTC) is now proven as the best choice for driverless systems because of the inherent high levels of safety and reliability with a low life cycle cost.

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.
