This paper verifies the obvious percolation phenomenon in the randomly distributed crowd by [Formula: see text] simulation and reveals several characteristics and laws of the crowd percolation phenomena. Studies have shown that sites with different spatial dimensions have different densities of crowd percolation: when the actual density of the crowd is greater than the critical density of the crowd percolation, the outsider is difficult to pass through the crowd; otherwise, the outsider can pass through the crowd easily. Therefore, the critical density of crowd percolation can be one of the indicators of crowd management in public areas, which will provide important guidance for the design of public areas, site selection of public activities and crowd management. <\/jats:p>","DOI":"10.1142\/s0218001420590442","type":"journal-article","created":{"date-parts":[[2020,2,17]],"date-time":"2020-02-17T10:41:36Z","timestamp":1581936096000},"page":"2059044","source":"Crossref","is-referenced-by-count":0,"title":["Study on Critical Density of Percolation in Crowds in Public Areas"],"prefix":"10.1142","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1689-0672","authenticated-orcid":false,"given":"Hui","family":"Guo","sequence":"first","affiliation":[{"name":"School of Safety Science and Emergency Management, Wuhan University of Technology, Wuhan 430070, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying-Hua","family":"Song","sequence":"additional","affiliation":[{"name":"China Research Center for Emergency Management, Wuhan University of Technology, Wuhan 430070, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Lv","sequence":"additional","affiliation":[{"name":"China Research Center for Emergency Management, Wuhan University of Technology, Wuhan 430070, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin-Yao","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Management Engineering, Zhengzhou University of Aeronautics, Zhengzhou 450015, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhi-Wu","family":"Lei","sequence":"additional","affiliation":[{"name":"School of Resources Environment and Safety Engineering, University of South China, Hengyang 421001, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2020,4,30]]},"reference":[{"issue":"2","key":"S0218001420590442BIB001","doi-asserted-by":"crossref","first-page":"315","DOI":"10.1016\/j.ssci.2010.09.006","volume":"49","author":"Alizadeh R.","year":"2011","journal-title":"Saf.
