A paper titled “Are driving errors and driving performance correlated? A dual structural equation model” authored by Panagiotis Papantoniou, George Yannis and Eleni Vlachogianni is now published in Advances in Transportation Studies. The objective of this paper is to investigate several factors (including driver distraction, driver characteristics and road environment) that affect overall driving error behaviour and estimates a new unobserved variable which underlines driving errors. This estimation is performed with data obtained from a driving simulation experiment in which 95 participants covering all ages were asked to drive under different types of distraction (no distraction, conversation with passenger, cell phone use) in rural and urban road environment, as well as in both low and high traffic conditions.
