The Relationship Between Driving Aberrant Behavior and Self-Reported Accidents Involvement Amongst Professional Bus Drivers in the Public Transportation Company

Abstract

Background: The most accidents can be directly attributed to human factors. Hence, more traffic crashes result from driver malfunctioning which from among them, the driver behavior is a proximal factor in the road traffic injuries causation chain. Objectives: This study aims to investigate relationship between aberrant driving behaviors questionnaire (DBQ factors) and self-report crashes involvement amongst professional bus drivers of public transportation system. Materials and Methods: This analytical descriptive study was performed on 161 urban bus drivers in Tehran. Proportional sampling method was used to select drivers from nine systems or areas. Data were collected through questionnaire including driver's behavior and their demographic information. Validity and reliability of the driver's behavior questionnaire for bus drivers had been confirmed in a previous study. Data collection was analyzed by Pearson correlation and regression logistic of in SPSS 16 of software. Results: Drivers reported accident involvement during the past three years with mean and standard deviation 2.4 ± 3.2, so that 31.1% had been involved in three or more accidents. There was a negative significant correlation between age and risky violation (P = 0.01). Furthermore, accidents involvement in the last three years was positively correlated with working hours per week (P = 0.003) and traffic offences (P = 0.005). Mistake as a driving aberrant behavior had a direct significant relationship with annual mileage (P = 0.020) and accidents involvement in last three years (P = 0.025). Conclusions: Bus driver’s crashes can be reduced by less driving time and mistakes which is dependent on mileage they drive.
