Real time information (RTI) unit works by sending a signal from one place of transportation services to RTI sign using satellite and radio communications. The signal from the vehicle is used to locate it along its route. A computer system uses this information to predict how long will the journey be.

There are RTI signs currently located in the local bus services all around London. Countdown is an electronic information display system that gives people waiting at bus stops real-time information on bus arrival times. The increasing use of information technology and electronic communications has raised travellers’ Expectations on the provision of transport information.
