The investigations have been based on data pooled from the answers of a survey of 136 motorcycle riders, with special regards to the correct detection of turning indicators. Experimental videos have been realized during in-situ simulations, both in urban and suburban areas, recording vehicular interactions in three-leg road intersections, able to potentially generate crash risks, through a 360-camera mounted on a motorcyclist\u2019s helmet. The blinkers detection rate has been combined with other factors related to motorcyclist\u2019s characteristics and test context (e.g., age, gender, location of the test site, presence of a car behind tester vehicles and if the motorcyclist are also habitual car or bicycle drivers) in a stepwise logistic regression that modelled the odds of detecting the turn signal turned on as a function of significant factors. Within the limits of the proposed methodology, the results highlight the low percentage of correct sighting of the turn indicators and confirm the existence of a relation between the detection of the turn indicators aspect and some of the variables considered (e.g., age, being habitual cyclist or car driver and the presence of a car occluding the views), suggesting the opportunity to further investigate the phenomenon through the use of ad-hoc simulations, in order to highlight connections among the factors that can influence the perception of turning indicators in potentially dangerous contexts for cars and motorcycles.<\/jats:p>","DOI":"10.3390\/s19081802","type":"journal-article","created":{"date-parts":[[2019,4,15]],"date-time":"2019-04-15T11:15:58Z","timestamp":1555326958000},"page":"1802","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Analysis of the Relationship between Turning Signal Detection and Motorcycle Driver\u2019s Characteristics on Urban Roads; A Case Study"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8662-8250","authenticated-orcid":false,"given":"Alfonso","family":"Micucci","sequence":"first","affiliation":[{"name":"Department of Civil, Chemical, Environmental and Materials Engineering\u2014DICAM, University of Bologna, viale del Risorgimento 2, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9049-6895","authenticated-orcid":false,"given":"Luca","family":"Mantecchini","sequence":"additional","affiliation":[{"name":"Department of Civil, Chemical, Environmental and Materials Engineering\u2014DICAM, University of Bologna, viale del Risorgimento 2, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5127-4701","authenticated-orcid":false,"given":"Maurizio","family":"Sangermano","sequence":"additional","affiliation":[{"name":"Department of Civil, Chemical, Environmental and Materials Engineering\u2014DICAM, University of Bologna, viale del Risorgimento 2, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,15]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2015, October 19).
