Analyzing the influence of the drivers' visual changes in highway tunnel groups on traffic safety, this paper made a test on 100 drivers' visual characteristics on Tongling to Tangkou (Anhui) expressway traffic tunnel group using the dynamic visual acuity tester. The results showed that: the drivers are relatively prone to accident in the tunnel group environment. After driving through the expressway tunnel group, drivers' dynamic visions are 47.12 percent and even up to 90.18 percent compromised, compared to their respective static vision. According to the gray system, a gray relation analysis model of visual characteristics was established. The results showed that the driving age, driving experience and continuous driving time all had strong correlations with drivers' dynamic vision, in which the continuous driving time dominates other factors. This paper could in theory provide a useful or practical way for the design and safety management of the expressway tunnel group.
