Background and Aim: The number of global fatalities in the road accidents is gradually rising, with many deaths and financial losses for different communities. The most important factor affecting the occurrence of traffic accidents and road accidents in different researches is human factor. Driving a car requires a seamless interaction of various cognitive abilities, including attention, perceptual motor skills, memory and decision making. This rich range of skills is needed for proper driving, and any weakness in any of these skills can lead to dangerous driving errors. Much of the metropolitan population is exposed to a lot of traffic noise daily, and it has been shown many of the car accidents are caused by attention problems following traffic noises, consequently to deal with this problem many studies have shown that cognitive training interventions can lead to cognitive gains in healthy adults. Cognitive software is one of the most important tools for cognitive rehabilitation and performance enhancement because they are the basis of cognitive exercises that can improve one's cognitive performance by engaging one's motivation. Methods In This study we used driving simulator equipped with virtual reality displays. A risk perception scenario was administered to the subjects in two conditions with and without traffic noise in ۲۴ healthy adults aged ۲۰-۴۰ years old was performed and then attention computerized cognitive rehabilitation was given to ۱۲ subjects for ۱۰ sessions, finally the changes of cognitive functions and driving quality of individuals in two stages before and after Cognitive rehabilitation was evaluated in two experimental and control groups. The experimental group was followed up for ۸ weeks after the cognitive training period. Results: The results of this study can be used to emphasize the importance of environmental noise on driving quality and the necessity of traffic noise control. On the other hand, considering the cognitive enhancement effect, using cognitive tools to enhancing attention and concentration and overall cognitive skills used in driving for city drivers who are constantly exposed to ambient noise to reduce accident risks and financial and health losses.. Conclusion By performing computer-based rehabilitation exercises of alertness, divided attention, attention and concentration, visual attention, sustained attention, exploration, vigilance and acoustic responsiveness, there were significant differences in planning, verbal and spatial working memory, speed processing, and different aspects of attention and driving quality were observed after the cognitive training period.
