Abstract
An elevator system (20) includes multiple cars (22, 24) within a hoistway (40). Parking positions (72, 74) are provided outside the range of passenger service levels (70). A destination entry strategy is used by a controller (60) for directing movement of the elevator cars (22, 24). The inventive combination of multiple cars in a hoistway, parking positions outside of the normal passenger service level range and destination entry car movement control allows for reducing car travel speed, reducing car size or both while still meeting desired handling capacity needs or even exceeding the desired handling capacity associated with another elevator system that requires larger cars, higher speeds and more building space.
