A paper titled “Which factors affect accident probability at unexpected incidents? A structural equation model approach” authored by Panagiotis Papantoniou, Constantinos Antoniou, George Yannis and Dimosthenis Pavlou is now published in Journal of Transportation Safety & Security. A driving simulator experiment was carried out, in which 95 participants were asked to drive under different types of distraction (no distraction, conversation with passenger, cell phone use) in different road and traffic conditions. Then, in the framework of the statistical analysis, driving performance is estimated as a new unobserved (latent) variable based on several individual driving simulator parameters while a structural equation model is developed investigating which factors lead to increased accident probability at unexpected incidents. Regarding driver distraction, results indicate that cell phone use has a negative effect on accident risk confirming the initial hypothesis that when talking on the cell phone drivers find it difficult to handle an unexpected incident and as a result are more likely to commit an accident.
