In the definition of the coverage region, the Euclidean distance was used, which is not suitable for measuring the length of a route between two places. This study improved on the previous one by redefining the coverage region for practical application and providing a simulation model to verify the effectiveness of the proposed ambulance allocation method. The simulation results show the proposed allocation method providing higher demand coverage rates and shorter response distances than the official allocation. <\/jats:p>","DOI":"10.1142\/s2424922x21500030","type":"journal-article","created":{"date-parts":[[2021,2,18]],"date-time":"2021-02-18T06:40:04Z","timestamp":1613630404000},"page":"2150003","source":"Crossref","is-referenced-by-count":1,"title":["Empirical Spatial Density-Based Emergency Medical Service Demand Forecast for Ambulance Allocation"],"prefix":"10.1142","volume":"13","author":[{"given":"Yihjia","family":"Tsai","sequence":"first","affiliation":[{"name":"Department of Computer Science and Information Engineering, Tamkang University, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1539-233X","authenticated-orcid":false,"given":"Hwei Jen","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, Tamkang University, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pei-Wen","family":"Chi","sequence":"additional","affiliation":[{"name":"Department of Emergency, School of Medicine, College of Medicine, Taipei Medical University, Taiwan"},{"name":"Department of Emergency and Critical Medicine, Taipei Municipal Wan-Fang Hospital, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kelvin W.","family":"Lee","sequence":"additional","affiliation":[{"name":"Simon Business School, University of Rochester, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2021,4,8]]},"reference":[{"key":"S2424922X21500030BIB001","doi-asserted-by":"publisher","DOI":"10.1080\/10903120701204797"},{"key":"S2424922X21500030BIB002","doi-asserted-by":"publisher","DOI":"10.3109\/10903127.2014.995843"},{"key":"S2424922X21500030BIB003","doi-asserted-by":"publisher","DOI":"10.1061\/9780784413616.203"},{"key":"S2424922X21500030BIB004","doi-asserted-by":"publisher","DOI":"10.1109\/JBHI.2015.2443799"},{"key":"S2424922X21500030BIB005","first-page":"4","volume-title":"29th AAAI Conf.
