A ramp assembly for providing a transition surface from a vehicle floor to an alighting surface includes a ramp position that rotates between a stowed position and a deployed position. A panel is rotatably coupled about an axis to the ramp portion. The ramp assembly further includes a support member that supports a first end of the panel. An actuator drives the ramp assembly through a deployment motion having a first phase and a second phase. During the first phase, the actuator rotates the ramp portion about the axis. During the second phase, the actuator moves the axis in a downward direction.
