00925njm 22002777a 4500 dc García Herrero, Susana author Gutiérrez, José Manuel author Herrera, Sixto author Azimian, Amin author Mariscal Saldaña, Miguel Ángel author 2020-05 To reduce traffic accidents, an accurately estimated model is needed to capture the true relationships between the injury severity and risk factors. This study aims to propose a robust procedure to address the biases in police-reported accident data and subsequently to conduct sensitivity analyzes in order to estimate the variations in injury severity and distraction probability based on drivers’ behaviors/characteristics and psychophysical conditions. The results show that: (i) the excess speed will likely increase the probability of serious/fatal injury for drivers of all age groups by 10%; (ii) distraction and driver’ errors will likely increase the probability of serious/fatal injury in all drivers driving at a proper speed up to 1.5%; (iii) alcohol and drug consumption can significantly increase the probability of being distracted and making errors by 28.5% and 33.5% respectively; (iv) Alcohol consumption reduces the probability of driving at an appropriate speed in drivers under 25 by 40%. However, the results for drugs consumption are not as significant as the ones for alcohol consumption. 0925-7535 http://hdl.handle.net/10259/9037 10.1016/j.ssci.2019.104586 Traffic accident Drugs Alcohol Speed Distraction Human error Bayesian network Bias identification Sensitivity analysis of driver's behavior and psychophysical conditions
