Answer: B: reduces voice traffic between dispatch and field units
Explanation:
Computer Aided Dispatch (CAD) is the use of an automated system to dispatch services that work with dispatches such as emergency vehicles, cabs, couriers and transport vehicles.
CAD reduces voice traffic between the dispatch and the field units because the conversation between the two are reduced on account of the dispatch being a computer that cannot/ will not have a conversation with the field units unless giving a location they have been dispatched to.
