Going Up: Destination Elevators Travel Faster

According to the Boston Globe, workers at One Federal Street in Boston are getting to their offices quicker thanks to the $4 million destination elevators recently installed in the 38-floor building. The first of their kind in Massachusetts, One Federal’s 23 destination elevators travel faster and more efficiently because each elevator only services certain floors, which reduces wait time by minimizing stops.

The system, originally developed by the Schindler Elevator Corp., uses artificial intelligence and complex computer algorithms to monitor traffic flow and adjust to heavier or lighter usage throughout the day. Wall-mounted keypads allow riders to type in where they want to go before directing them to the appropriate elevator, though piggy-backing, a problem that occurs when passengers don’t key in the floor they want because somebody else already has, can potentially cause overcrowding. The opposite of piggybacking, when a single person keys in the floor they want multiple times, can also cause inefficiencies.

However, these problems can be accounted for with load-weighing technology that estimates how many people actually boarded the elevator versus how many times the floor number was keyed in. Schindler has installed about 3,000 systems globally, while competitor Otis Elevator Co. has done 20 projects. Fujitec Co., a recent entry into the destination elevator market, is represented by two systems in Seattle.     EC
