[1][2][3][4][5] CentreComm's primary purpose is to provide an emergency control centre for London Buses contracted bus network.
CentreComm was conceived in 1979 and consisted of a mere handful of people equipped with two-way radios and paper records.
Through GPS fitted to each of London's buses they can monitor their location at all times.
For bus drivers, conductors and passenger assistants their services are activated via the IBus (London) system by initiating a code red (emergency) or code blue (information) call.
For garage-based bus operator staff they are contacted via the telephone or by email.
