Study on the Assessment Scale of a Driver’s Risk Awareness in China

Driver error is the main cause of accidents, doing research into a driver’s risk awareness helps us to know the issues in regard to driving safety. Based on the review of related literature, an evaluation index system of a driver’s risk awareness with an appropriate scale was established. The index system contains three first class indices (risk attitude, risk behavior and risk perception) and together covers fourteen secondary indices (general attitude towards obeying rules, aggressive violations and awareness of safe driving, etc). There are three subscales which are Risk Attitude Scale (48 items), Risk Perception Scale (22 items) and Risk Behavior Scale (27 items). A survey was conducted in China, 240 drivers participated in this anonymous questionnaire survey. Based on the survey, the scale was revised by the T-testing, correlation testing, and scale reliability and validity testing. Exploratory factor analysis was used to examine the construct validity of scale. In addition, the survey results were statistically analyzed to verify the feasibility and efficiency of the scale.
