Abstract
An audible warning cue signal of a selected duration is provided to disembarked passengers to warn them of the impending departure of the vehicle from which they disembarked. The vehicle is stopped at a predetermined location for passenger debarkation. An entrance door of the vehicle is then actuated to an opened condition to allow the passengers to disembark. After the passengers have disembarked, the door is actuated to a closed condition and an audibly perceptible alarm is provided for a selected time duration to aurally alert the disembarked passengers to the impending departure of the vehicle.
