Research on Beijing Bus Driver Psychology Fatigue Evaluation

As the capital and political centre of China, Beijing's motor vehicle ownership, road congestion and flow intensity are all increasing. The traffic accident explosion has become a growing number of serious social problems, and the driver's driving safety requirements are higher. In this background, the research on Beijing bus driver's mental fatigue becomes a critical issue in reducing road accidents, decreasing passengers’ injuries, and ensuring safe operation. Psychology Fatigue Measurement System was established in the experiment. Critical flicker fusion test, perceptual speed test, distribution of attention value test, reaction time test were used to test drivers of three types of buses, and then Wilcoxon non-parametric test was used to calculate significance of data changes with SPSS. This thesis reveals the Beijing bus drivers’ fatigue evaluation index changing trends under different driving models and running time. As a conclusion, changes of each index obtained obey normal distribution, and changes in indicators are independent. The changes of the fatigue test index are discovered caused by different buses and different time.
