Based on the route selected, whenever the bus is close to the bus stop location, the controller alerts the driver of the next bus stop. It also announces the next bus stop on internal speakers. At the bus stop, the driver initiate the announcement of destination and major stops on external speakers for convenience of the passengers standing at the Bus stop. Similarly, the requisite messages are sent to the various display boards at appropriate times. This is controlled by the driver. The System also controls the LED at the Bus Stand that displays the Estimated Time of Arrival of the next bus. This information to sent to it from the Bus via GPRS.
