5.1.7.3.6---Provide Transit Vehicle Operator Interface for Emergencies (Pspec*)

This process shall provide an interface between the transit vehicle operator and the transit vehicle for emergency and surveillance control functions. The operator shall be able to report an emergency situation and receive an acknowledgment from the transit or emergency management function that the emergency request has been received. The process shall provide this interface in such a way that its operation for both inputs and outputs shall be transparent to travelers on board the vehicle and to anyone outside the vehicle, and shall not compromise the safe operation of the vehicle by the operator. The process shall provide wide area alert information to the operator. The process shall perform authentication of the transit vehicle operator, which can be done in a variety of ways, either on the vehicle or at the Transit Management Center. If authentication is done on the vehicle, the database of valid transit vehicle operators stored on the vehicle is periodically updated. The process shall accept surveillance control inputs from the transit vehicle operator and output that controls the on-board surveillance equipment. The process shall forward video and audio outputs to the vehicle operator.
