COVID-19 大流行期间的社交距离要求给严重依赖电梯进行垂直运输的高层建筑带来了重大挑战。特别是，出于社交距离的需要，电梯容量通常会减少正常容量的至少三分之二或多达 90%$90\%$。这种减少是一个严重的问题，因为电梯容量的减少会导致大厅里排起长队，这使得保持社交距离变得困难并导致等待时间过长。本研究的目的是通过提出简单、无技术的干预措施来安全地管理电梯队列，从而大大减少等待时间和大厅队列的长度。我们使用数学模型、流行病学专业知识和模拟来设计和评估我们的干预措施。关键思想是尽可能将前往同一楼层的乘客显式或隐式地分组到同一部电梯中。在队列干预中，我们尝试找到与队列中第一个人去同一楼层的乘客。在队列分割干预中，我们为不同的楼层组创建不同的队列。根据模拟和分析结果，分组和队列分割可以显着减少队列长度和等待时间，同时还可以在拥挤的电梯、大楼大堂和入口处保持病毒传播的安全性。这些干预措施通常适用于许多建筑物，因为它们不需要对电梯进行编程，并且仅依靠标牌和/或队列管理器来引导乘客。
The requirement of social distancing during the COVID‐19 pandemic has presented significant challenges for high‐rise buildings, which heavily rely on elevators for vertical transportation. In particular, the need for social distancing has reduced elevator capacity typically by at least two‐thirds or as much as over 90%$90\%$ of the normal amount. This reduction is a serious concern, as reduced elevator capacities cause large queues to build up in lobbies, which makes social distancing difficult and results in large wait times. The objective of this study is to safely manage the elevator queues by proposing simple, technology‐free interventions that drastically reduce the waiting time and length of lobby queues. We use mathematical modeling, epidemiological expertise, and simulation to design and evaluate our interventions. The key idea is to explicitly or implicitly group passengers that are going to the same floor into the same elevator as much as possible. In theCohortingintervention, we attempt to find passengers going to the same floor as the first person in the queue. In theQueue Splittingintervention, we create a different queue for different groups of floors. Based on simulation and analytical findings, Cohorting and Queue Splitting can significantly reduce queue length and wait time, while also maintaining safety from viral transmission in otherwise crowded elevators, building lobbies, and entrances. These interventions are generally accessible for many buildings since they do not require programming the elevators, and rely on only using signage and/or a queue manager to guide passengers.
