Every year, several deaths are caused by this phenomenon, even though a lot of money is invested in raising awareness and in the development of prevention systems. In this paper, a blind spot detection and warning system is proposed, relying on Received Signal Strength Indicator (RSSI) measurements and Bluetooth Low Energy (BLE) wireless communication. The received RSSI samples are threshold-filtered, after which a weighted average is computed with a sliding window filter. The technique is validated by simulations and measurements. Finally, the strength of the proposed system is demonstrated with real-life measurements.<\/jats:p>","DOI":"10.3390\/s20092727","type":"journal-article","created":{"date-parts":[[2020,5,11]],"date-time":"2020-05-11T12:26:30Z","timestamp":1589199990000},"page":"2727","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["A Bluetooth-Low-Energy-Based Detection and Warning System for Vulnerable Road Users in the Blind Spot of Vehicles"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7720-316X","authenticated-orcid":false,"given":"Nick","family":"De Raeve","sequence":"first","affiliation":[{"name":"IDLab, Department of Information Technology, Ghent University-imec, Technologiepark-Zwijnaarde 126, 9052 Gent, Belgium"}]},{"given":"Matthias","family":"de Schepper","sequence":"additional","affiliation":[{"name":"IDLab, Department of Information Technology, Ghent University-imec, Technologiepark-Zwijnaarde 126, 9052 Gent, Belgium"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4003-0098","authenticated-orcid":false,"given":"Jo","family":"Verhaevert","sequence":"additional","affiliation":[{"name":"IDLab, Department of Information Technology, Ghent University-imec, Technologiepark-Zwijnaarde 126, 9052 Gent, Belgium"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0633-0815","authenticated-orcid":false,"given":"Patrick","family":"Van Torre","sequence":"additional","affiliation":[{"name":"IDLab, Department of Information Technology, Ghent University-imec, Technologiepark-Zwijnaarde 126, 9052 Gent, Belgium"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8139-2736","authenticated-orcid":false,"given":"Hendrik","family":"Rogier","sequence":"additional","affiliation":[{"name":"IDLab, Department of Information Technology, Ghent University-imec, Technologiepark-Zwijnaarde 126, 9052 Gent, Belgium"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,11]]},"reference":[{"key":"ref_1","unstructured":"Veiligverkeer.be (2020, May 07).
