Many times when people push up / down button for using elevator cabin, they may need to wait so long because of other people using the cabin in other floors. As a result some of them prefer other cabins or many choose staircase however, the cabin is programmed to arrive chosen floor even if there are no longer any people there .This problem is so common in places such as hospitals, hotels, and condominiums.
