The driver of Tibet is a remarkable representative of the plateau driver. In order to analyze the characteristics of the drivers’ situational awareness, the situational awareness scale was designed, and the correlation between the drivers' situational awareness and accident, and the influence factors of situational awareness were discussed based on data. The results show that there is a significant positive correlation between the illegal traffic behavior and the traffic accident. There is a significant negative correlation between Tibetan drivers' situational awareness and responsible traffic accidents. When the indicators such as gender, age, driving experience, driving distance, driving time and driving distance in Tibet are at different levels, there is a significant difference in the situational awareness of the drivers in Tibet, and there is no significant difference in the overall situational awareness between the local drivers and non-local drivers. The research results can provide certain reference value for traffic safety management and related research of plateau drivers.
