ABSTRACT:
A passenger flow arrangement for use in moving passengers between two floors in elevator-like cabs allow the passenger to continue to face in a forward direction and exit the vehicle after having entered in the forward direction. In one aspect of this invention, a cab door on one side of the cab opens at a first of the floors, and a door on an opposed side of the cab opens at a second of the floors. In other arrangements, there are cab doors at each side of the cab, and one of the cab doors opens as an entrance door while the other opens as an exit door. Appropriate signals such as signs or door opening timing prompt the passengers to face and move in the appropriate directions.
