Abstract
Currently, the introduction of the careful driving support system has been pushed forward for traffic accident number reduction. Therefore, in this study, I am aimed for the development of a traffic simulator judging whether a careful driving support system is effective. I use a universal driver model for this traffic simulator. However, the effectiveness of the universal driver model becomes the problem. I tested it about the recognition region and judgment region to bring a universal driver model close to the driving action of the real driver in this year. I modeled it from this result.
