Road accidents have a relevant impact in terms of economic and social costs. As a consequence, many researchstudies have focused on identifying the key factors affecting accident severity. Traditionally, these factors canbe included in the infrastructural, human and vehicle groups. Among these, human factors have a relevant impact onaccident severity, which depends on driving experience, driver’s socio-economic characteristics, and driving behaviour,but also on the driver’s psychological state while driving. In this paper we investigate on the relationships between drivingbehaviour usually taken by the driver and his/her perceived psychological state while driving. In order to achievethis goal we adopt an Ordered Probit (OP) model formulation calibrated on the basis of experimental data collected bya sample survey. We demonstrate that the adopted methodology accounts for the differential impacts of certain humanfactors on driver’s psychological state.

Abstract

Road accidents have a relevant impact in terms of economic and social costs. As a consequence, many researchstudies have focused on identifying the key factors affecting accident severity. Traditionally, these factors canbe included in the infrastructural, human and vehicle groups. Among these, human factors have a relevant impact onaccident severity, which depends on driving experience, driver’s socio-economic characteristics, and driving behaviour,but also on the driver’s psychological state while driving. In this paper we investigate on the relationships between drivingbehaviour usually taken by the driver and his/her perceived psychological state while driving. In order to achievethis goal we adopt an Ordered Probit (OP) model formulation calibrated on the basis of experimental data collected bya sample survey. We demonstrate that the adopted methodology accounts for the differential impacts of certain humanfactors on driver’s psychological state.
