Drivers know when customers are about to be dropped off, so we have a button in our Driver Application that allows a message to be sent to the dispatcher notifying them to expect them to clear. That information is helpful to dispatchers to know when their driver are about to be cleared. Then dispatchers can have a better idea on whether to accept more calls to pickup customers. Sometimes calls come in all at once and it is difficult to determine driver status.
Now you have that information available and sent to the dispatcher.
