Proactive management at mass gatherings is vital to ensure safe crowd evacuation during emergencies. The increasing number of crowd incidents and casualties during the Hajj season is one of the major concerns for authorities in Saudi Arabia. This study aims to explore and analyze crowd dynamics visiting the Prophet's (PBUH) tomb at the visiting (Ziara) corridor in the Holy Mosque of Madinah under continuous flow conditions. MassMotion was used to optimize the crowd flow rate with density restricted to a safe threshold value for efficient crowd management. A robust regression model has been developed to guide the authorities for the safe and efficient operation of the visiting corridor. The study results showed that the crowd flow beyond 9200 persons/h and waiting time in excess of 42 s in front of Moajha might lead to breakdown condition. The output of this study can be utilized by decision-makers and concerned authorities to take appropriate and timely remedial actions to ensure safe, smooth, and efficient crowd management.

群众聚会的准备:基于模拟的人群监控数据流控制和管理框架

群众聚会上的积极管理对于确保紧急情况下人群的安全疏散至关重要。朝j季期间人群事件和伤亡人数的增加是沙特阿拉伯当局关注的主要问题之一。本研究旨在探讨和分析在连续流动条件下,麦地那圣清真寺的来访者(Ziara)走廊参观先知(PBUH)墓的人群动态。MassMotion用于优化人群流量,其密度限制在安全阈值以进行有效的人群管理。已经开发了鲁棒的回归模型来指导当局确保访问走廊的安全和有效运行。研究结果表明,超过9200人/小时的人群流量以及Moajha前方的等待时间超过42 s可能会导致故障情况。
