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.
