Claim:
1. A passenger compartment of a transportation vehicle, comprising: a floor, opposing side walls extending from the floor, and a ceiling extending from the side walls, wherein said floor, said side walls, and said ceiling define an enclosed space; a plurality of rows of seats for passengers on the floor in the enclosed space; one or more side ventilation air inlets at an upper portion of each side wall to provide incoming airflows into the enclosed space; one or more ventilation air outlets at a lower portion of each side wall for receiving outgoing airflows from the enclosed space, and a plurality of redirector members, each said redirector member being bent-shaped in cross-section comprising an airflow dividing leg connected to an airflow redirecting leg, wherein the dividing leg and the redirecting leg of each redirector member form a generally L-shape in cross-section, wherein the dividing leg includes a pointed upstream edge and expands in profile in cross-section as it extends in the downstream direction, and wherein the redirecting leg expands in profile in cross-section as it extends in the downstream direction away from the dividing leg, each said redirector member being mounted in a different one of said one or more side ventilation air inlets to divide and stratify the incoming airflow, wherein the dividing leg is positioned in the incoming airflow to cause a first portion of the incoming airflow to flow along a lower side of the dividing leg and the redirecting leg and downwardly toward the seats and a second portion of the incoming airflow to flow along an opposite upper side of the dividing leg, wherein the redirector member cooperates with the ceiling of the cabin to divide the second portion of the incoming airflow into a portion flowing on the ceiling and a portion flowing on an opposite upper side of the redirecting leg and downwardly toward the seats to create air curtains between the seats to inhibit transmission of pathogens and disease between the passengers.
