Abstract
Elevator functioning as a vertical transport facility remains stand-alone and incapable of accessing the fine-grained traffic information. It significantly restricts the flexibility and efficiency of vertical transporting. In particular, while in peak-time, the limited elevator physical capacity with the momentary traffic increment gives rise to the vertical traffic bottleneck problem in large-scale buildings. The problem further results in the long waiting, dissatisfaction, frustration of passengers. In this paper, we present our proposal named Intellevator: an intelligent elevator system that enables the passively functioning elevator system be proactive and intelligent in traffic control for optimizing the transport efficiency. The proposal is an end-to-end architecture that composed of three aspects: Internet of things (IoT)-enabling technology on a conventional elevator; an agent server to enhance elevator computational capability and a novel user interface for delivering system intelligence to end-users. The proposal was experimented on a conventional elevator in a built smart-building environment. Numerical simulation results have demonstrated the system efficiency improvement. In addition, the system usability and user experience have been evaluated by a user study as well.

This paper presents our proposal of an intelligent elevator system - Intellevator for improving the intelligence and the time-efficiency by proactive traffic control
Passive transport method (PT) is the method widely applied on the traditional elevator system, by which the elevator system is passive in reaction to all the transport requirement
Summary
Elevator, functioning as a vertical transporting device, remains stand-alone from the communication infrastructure in the building and is required to be more accessible [1]. According to Smarter Buildings Study [2], the investigation of 6,486 office workers in 16 U.S cities revealed that the total amount of over 92 years was wasted on waiting for elevators in 2009. Future Design [3] revealed that nearly 80 percentage of subjects (totally 1030) have indicated that the waiting time of elevators is excessively long and need to be shortened. While under the peak time, the momentary increment of traffic load always rises the vertical traffic congestion problem. Multi-car elevator (MCE) systems have been deployed in the large-scale commercial buildings. A few of them were set as: several cabins go to the
