A set of wireless sensor nodes using the Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 standard with additional internet protocol (IP) connectivity measures both ambient conditions and vehicle transit. These measurements are sent to a coordinator node that collects and passes them to a local controller, which then makes decisions leading to the streetlight being turned on and its illumination level controlled. Streetlights are autonomous, powered by photovoltaic energy, and wirelessly connected, achieving a high degree of energy efficiency. Relevant data are also sent to the highway conservation center, allowing it to maintain up-to-date information for the system, enabling preventive maintenance.<\/jats:p>","DOI":"10.3390\/s19235101","type":"journal-article","created":{"date-parts":[[2019,11,22]],"date-time":"2019-11-22T02:49:27Z","timestamp":1574390967000},"page":"5101","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["ITERL: A Wireless Adaptive System for Efficient Road Lighting"],"prefix":"10.3390","volume":"19","author":[{"given":"Mar\u00eda","family":"Garc\u00eda-Castellano","sequence":"first","affiliation":[{"name":"Departamento de Ingenier\u00eda Electr\u00f3nica, ETS Ingenieros, Universidad de Sevilla, 41092 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Manuel","family":"Gonz\u00e1lez-Romo","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Electr\u00f3nica, ETS Ingenieros, Universidad de Sevilla, 41092 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1304-8372","authenticated-orcid":false,"given":"Juan Antonio","family":"G\u00f3mez-Gal\u00e1n","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Electr\u00f3nica, Sistemas Inform\u00e1ticos y Autom\u00e1tica, Universidad de Huelva, 21007 Huelva, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7755-0065","authenticated-orcid":false,"given":"Juan Pablo","family":"Garc\u00eda-Mart\u00edn","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Electr\u00f3nica, ETS Ingenieros, Universidad de Sevilla, 41092 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Torralba","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Electr\u00f3nica, ETS Ingenieros, Universidad de Sevilla, 41092 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ventura","family":"P\u00e9rez-Mira","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Qu\u00edmica y Ambiental, ETS Ingenieros, Universidad de Sevilla, 41092 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"139","DOI":"10.1016\/j.iatssr.2012.09.001","article-title":"Quantifying the impact of road lighting on road safety\u2014A New Zealand Study","volume":"36","author":"Jackett","year":"2013","journal-title":"IATTS Res."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"601","DOI":"10.1080\/15389588.2018.1471599","article-title":"Evaluating the influence of road lighting on traffic safety at accesses using an artificial neural network","volume":"19","author":"Xu","year":"2018","journal-title":"Traffic Inj.
