Attention Characteristics of Drivers under Risky Traffic Situations

摘要

This paper aims to study the attention characteristics of drivers under the multiple risky traffic situations. Based on correlation analyses of drivers' attributes, risk attributes, and drivers' attention characteristics, drivers' multiple risky gravity integrated model is constructed to measure the attention degrees. By simulating driving experiment, it studies on drivers' fixation time to risk, the impact of running speed, and distance on drivers' risky gravity and analyzes the relationship between risky gravity and drivers' attention characteristics under multiple risky traffic situations. The result shows significant difference of risky gravity between experienced and inexperienced drivers under multiple situations. Risky gravity of inexperienced drivers is significantly greater than that of experienced drivers. By analyzing the impact of running speed on drivers' risky gravity, it shows that the higher running speed, the greater risky gravity, the more attention demanded, thus running speed has a bigger impact on traffic safety.
