Free hazard perception test 20114/12/2023 ![]() Hazard perception ability, which develops with driving experience, has been proven to be associated with drivers' traffic involvement. Conclusions: Application of this valid test is suggested for assessing the hazard perception of drivers, particularly those who are responsible for transporting staff and goods in the studied country. ![]() Eventually, the 18-videos of the valid test became HPT software. There was a significant correlation between active neurons and miss rate (r = 0.556, P < 0.001). Results: The mean differences in reaction time, miss rate, and active neurons in the task of perceiving hazards in two groups of drivers were equal to 1.58 seconds, 29.55%, and 5248 neurons, respectively. Finally, using 18 videos with statistically significant differences in neuro-cerebral neuronal activity, miss rate and reaction time were picked up for driver’s HPT. In the second step, 35 selected videos were broadcasted to 16 experienced and 16 novice drivers on a functional magnetic resonance imaging (fMRI). Miss rates and reaction times to hazardous situations were measured. The validity of the test was performed in three steps. Then, hazard onset was determined for screened videos. All videos were screened according to some quality factors. Methods: Different roads, including urban, intercity, and rural, were filmed from drivers’ visual angles to examine the real road conditions. Objectives: This study aimed to design a valid and reliable driver’s Hazard Perception Test (HPT) based on neural imaging, reaction time, and miss rate in two groups of experienced and inexperienced drivers. Implications for driver licensing, evaluation and training are discussed.īackground: Studies show that weakness in hazard perception is a major cause of traffic accidents, leading to high consequences. ![]() Results suggest that this brief test of hazard perception can discriminate groups that differ in driving experience. There was good reliability in the resulting scale. After selecting those scenes with the larger group differences, an 18-scene test that would be useful for mass testing exhibited even larger experience effects. Novices were significantly slower in responding to hazards, even after controlling for age and simple reaction time. experienced drivers of similar age) on the basis of individual differences in reaction time, miss rate and false alarm rate. After eliminating those scenes that were problematic (e.g., many observers did not recognize the hazard), we predicted driver group (novice vs. We developed a hazard perception test, modeled on that used currently in several Australian states, that presents short video scenes to observers and requires them to indicate the presence of a traffic conflict that would lead to a collision between the "camera" vehicle and another road user. ![]()
