Studies on crowd characteristics and management strategies are imperative for modern metro stations. Previous studies mainly focused on pedestrian facilities like sidewalks or crossing, while this research aims to evaluate the efficiency and safety performance of metro stations by introducing a new concept, pedestrian level of service (PLOS). The authors divide a station into separate locations in four typical types: exits, stairways, corridors, and open areas. The characteristics of pedestrians in these four types of locations are delineated and a new index called the interaction index (II) is proposed to quantify the performance. By integrating the II values of all single locations, the PLOS of the whole station can be analyzed. To validate this method, field data were collected and compared. Finally, the Caobao Road metro station in Shanghai was used as a case study for the practical application.

对于现代地铁站，必须研究人群特征和管理策略。先前的研究主要集中在人行道或人行横道等行人设施，而本研究旨在通过引入新概念行人服务水平（PLOS）来评估地铁站的效率和安全性能。作者将车站分为四种典型类型的独立位置：出口，楼梯，走廊和开放区域。描绘了这四种类型的行人的特征，并提出了一个新的指标，称为交互指标（II）来量化性能。通过积分所有单个位置的II值，可以分析整个站的PLOS。为了验证该方法，收集并比较了现场数据。最后，
