An investigation on the relationship between demographic variables, driving behaviour and crash involvement risk of bus drivers: A case study from Iran.

The aim was to model the bus drivers' crash involvement risk as a function of their demographic factors and driving behaviour. 177 bus drivers completed a questionnaire containing the BDRI questionnaire. 19.2% of respondents had at least been involved in one at-fault crash during the past three years. In addition, age-group and having a second job were found to affect crash involvement rate. Smoker drivers reported significantly lower scores in Patient driving and Anxious driving factors. Results also indicated that vehicle ownership could improve hazard monitoring and thrill seeking behaviours of bus drivers. Logistic regression suggested that ≥55 years old drivers are 5.4 times more likely to be involved in crashes, compared with <35 years old drivers. Model results also implied that the odds of crash involvement would decrease by 39%, for each one unit improvement in the scores of Hazard monitoring behaviour. Implications are further discussed.
