If you’re unfortunate enough to work in a tall building (over 10 floors), you know what a pain in the neck it is to take the elevators during rush hour (morning, lunch time and evening). Hitachi has worked on a system to boost the whole thing by making not one but 6 to 8 elevator cabins and a system like a big wheel. the idea is to limit the waiting time for everyone because there is always an elevator cabin available. The entry and exit of the elevator will not be situated at the same place though.
