Yılmaz, Şerife
The aim of the present study was to develop a comprehensive scale measuring professional drivers' driver behaviors. For this reason, a semi-structured interview form was prepared and applied to different professional driver groups in order to collect behavioral examples displayed in traffic context (Study 1). These examples were grouped based on Reason's taxonomy of human error and Professional Driver, Driver Behavior Scale (PDBQ) was developed. PDBQ along with some other behavior scales such as ODBQ and DBQ was applied to different professional drivers (Main Study). PDBQ items were factor analyzed, and 3-factor solution was found more appropriate. These factors were called as Incompliance Mobility (favor sustaining mobility over safe driving), Positive Professional Driver Behaviors (safe practices in traffic environment, such as caring about other road users, helping and/or warning others in need, supporting traffic flow etc.), and Inappropriate Benefits (gaining benefits in traffic by posing risk to other road users). Moreover, three different ANCOVA was conducted to compare a group of drivers in terms of the driver behaviors factors emerged in the PDBQ. Results revealed that the van and cargo drivers are more likely to want to gain benefits in traffic at the cost of performing lawless behaviors. Results of two studies were discussed in the light of literature, contributions and limitations of the study were mentioned in detail.
