The Role of Journey Purpose in Road Traffic Injuries: A Bayesian Network Approach
Journal of Advanced Transportation. 2019, art. 6031482
Fecha de publicación
Road tra c injuries are now regarded as the eighth leading cause of death globally. For example, in 2016, 102,362 tra c injuries took place in Spain in which 174,679 drivers su ered injuries. ese ndings necessitated the development of the current study which focuses on the prime factors that cause this type of injuries. e aim of this study, therefore, is to explore the behavioral factors that entail a higher risk of su ering either a serious or a fatal injury for drivers. Methods. e ndings are based on information and data provided by “Dirección General de Trá co” (DGT) in Spain on tra c injuries that occurred in the year 2016. Reviewing a wide range of the literature, the authors identi ed the most in uential variables and created a model using the Bayesian networks. e variables that de ne the model are grouped into four factors: vehicle factor, road factor, circumstantial factor and human factor. Results. e results suggest that the principal variables that determine a higher probability of serious or fatal injuries in tra c injuries are: lack of using appropriate safety accessories, high-speed violations, distractions as well as errors. Finally, the research shows the severity probability based on reason of displacement (“in itinere,” on business, or in leisure).
