Fairness Improvement of Waiting Time between General Passengers and Priority Access Passengers in Elevator Group Control System using Cameras

Abstract

We propose the elevator group control method to fairly allocate the cars to all types of waiting passengers including ordinary passengers and priority access passengers who, for example, have strollers or need wheelchairs, in order to achieve fair waiting time as well as efficient transportation. Elevators are necessary for priority persons to move vertically within the building. However, due to the limited capacities, priority passengers who require more spaces often force to wait for a longer time until cars with vacant space arrive. On the other hand, many cameras that monitor the environments have become common and we can estimate the number of waiting passengers with the sizes of their possessions in elevator halls. Therefore, by using this information on passengers, the proposed control attempt to achieve fair latency. The experimental results using the simulated elevator control indicated that our method could make waiting time fairer and achieved the total efficiency to carry passengers.
