With a view point of space factor in large-scale buildings, this paper first overviews several mass transportation systems and compares their characteristics. Then a loop-type independent-driven multiple-cage elevator system and its high-efficient control method are proposed, The multiple-cage elevator system can reduce its shaft space as half as that of normal elevator system. Computer simulations show the proposed control method can improve waiting time and round trip time, and restrain needless stops. The loop-type multiple-cage elevator system may be feasible for the third transportation system which fills the gap between elevators and escalators in the near future.
