DOMINGUEZ, Cristina; FEBRES EGUIGUREN, Juan Diego  e  CUADRA, Steven N.. Uncovering road traffic crashes typologies using multiple correspondence analysis (MCA), in low-resource settings. Rev.fac.ing.univ. Antioquia [online]. 2023, n.107, pp.113-130.  Epub 18-Jul-2023. ISSN 0120-6230.  https://doi.org/10.17533/udea.redin.20220786.

The main focus of this study was to investigate self-reported road traffic crashes (RTC) among drivers from Loja, Ecuador, and to illustrate the applicability of multiple correspondence analysis (MCA) in detecting and representing typologies of individuals who have experienced an RTC as well as the typology of RTC events, upon information collected through a web-based survey carried in 2021. Overall, 754 drivers were investigated, and we estimated a life prevalence (LP) of RTC of 41.5% (95% CI 36.9 to 46.2). The typology of drivers who reported involvement in an RTC is characterized by a predominance of people between 25 to 40 years of age, who drive mainly cars and frequently experience distraction and use of a mobile phone when driving. Additionally, MCA indicated two distinctive typologies of RTC events. One is characterized by vehicle-to-vehicle collisions, due to behavioral factors, occurring at low-speed limit roads during the afternoon. The second one is characterized by collision with fixed objects or animals occurring at average-speed limit roads during the evening and late evening. Our study revealed major determinants of RTC are modifiable behavioral factors and that MCA is both a valid exploratory tool to identify individual and event typologies of under at most risk to suffer an RTC and a feasible technique to be implemented in low-income countries such as Ecuador.
