The intelligent analysis of this data leads to the identification of extremely useful patterns when making decisions in situations related to urbanism, traffic and road congestion, among others. This article presents a GPS trajectory clustering method that uses angular information to segment the trajectories and a similarity function guided by a pivot. In order to initialize the process, it is proposed to segment the region to be analyzed in a uniform way forming a grid. The obtained results after applying the proposed method on a real trajectories database are satisfactory and show significant improvement in comparison with the methods published in the bibliography.<\/jats:p>","DOI":"10.3233\/jifs-179644","type":"journal-article","created":{"date-parts":[[2020,2,11]],"date-time":"2020-02-11T10:46:45Z","timestamp":1581418005000},"page":"5529-5535","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["GPS trajectory clustering method for decision making on intelligent transportation systems"],"prefix":"10.1177","volume":"38","author":[{"given":"Gary","family":"Reyes","sequence":"first","affiliation":[{"name":"Universidad de Guayaquil, Facultad de Ciencias Matem\u00e1ticas y F\u00edsicas, Casilla Postal 471 Guayaquil, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Lanzarini","sequence":"additional","affiliation":[{"name":"Universidad Nacional de La Plata, Facultad de Inform\u00e1tica, Instituto de Investigaci\u00f3n en Inform\u00e1tica LIDI (Centro CICPBA) 1900 La Plata, Buenos Aires, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Waldo","family":"Hasperu\u00e9","sequence":"additional","affiliation":[{"name":"Universidad Nacional de La Plata, Facultad de Inform\u00e1tica, Instituto de Investigaci\u00f3n en Inform\u00e1tica LIDI (Centro CICPBA) 1900 La Plata, Buenos Aires, Argentina"},{"name":"Investigador Asociado \u2013 Comisi\u00f3n de Investigaciones Cient\u00edficas (CIC)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aurelio F.","family":"Bariviera","sequence":"additional","affiliation":[{"name":"Universitat Rovira i Virgili, Department of Business, Av.
