To study the relationship between driver decision characteristics and driving styles, two experiments were conducted. The first experiment used the Iowa gambling task (IGT) to collect the decision-making characteristics of drivers. The second experiment used the Chinese version of the multidimensional driving style inventory (MDSI-C) to collect driving style data. A final sample of 64 test subjects was required to fill in the driving style scale and participate in the Iowa gambling task experiment. Through data analysis using SPSS, driving style, and decision characteristics were obtained. The correlation shows that the feeling-seeking, risky, and anxious driving styles are impacted by gender. Aggressive and conservative drivers have significantly different driving styles; conservative drivers tend to be anxious while aggressive drivers tend to be risky. The results reveal the relationship between driving decisions and driving style and provide a basis for further exploring the impact of driving decisions on driving behaviors.
