The Relationship between Fatigue and Driving Behavior with the Mediated Role of Public Health in 45-65-Year-Old Traffic Users in Tehran

The analysis of road accidents in Iran shows that the most important factor in the occurrence of traffic accidents in Iran is the human factor. Therefore, the present study aimed to investigate the relationship between fatigue and driving behavior with the mediator variable of public health in traffic users. In order to achieve this goal, 169 people were selected from all traffic users in 22 traffic areas of Tehran who had traffic accidents. The tools used in this study included Manchester Driving Scale, General Health Questionnaires and Chalder Fatigue Scale. The proposed model was evaluated by Structural Equation Modeling (SEM) using SPSS software, version 18 and LISREL. The results showed that general health is a complete mediator of fatigue and driving behavior. The proposed model also fits in well with the data. According to the findings of the study, one of the criteria for granting a driving license with public vehicles can be considered as public health assessment. The traffic police can also train traffic users in the majority of commercials, according to the findings of the study.
