The comparative study of the performance impact of beginner and experienced drivers on traffic accidents (case study: service drivers of automotive companies’ staff in Region 21 of Tehran)

This study aims to compare the performance impact of beginner and experienced drivers on traffic accidents in Region 21 of Tehran. The hypothesis suggests that there is a significant difference between the performance of beginner and experienced drivers, as well as between the performance of beginner drivers with together. It presents results obtained through observation, in naturalistic situation, resorting to Lund Observation Protocol (originally developed by Riser, 1985), and intends to contribute to the understanding of driving performance with beginners and experienced drivers, considering two roadway paths (Shahid Lashgari & Fathh). Data collection was performed through video recording. Sample is made up of 30 participants (service drivers of automotive companies’ staff), equally divided by beginners and experienced drivers. For data analysis, descriptive and inferential statistical analyses were applied. Results indicate that driving task experience has a statistically significant effect on overall performance and some specific performance aspects (such as speed and overtaking); thus the hypotheses are confirmed. Research results contribute and reinforce not only the importance of systematizing knowledge, but also the value of initial and continuous training of drivers
