Abstract
The purpose of this study is to examine with emphasizing visual information about method of driver's information processing in different situations. Firstly, it seems that visual information is the most important for drivers, because the information takes about 90% in the total driver's information. And also, the objects in the environment are constructed by some elements, color, size, relative position, relative velocity, and so on. Therefore, we constructed a driver model which reproduced driver's control action including expression of some objects. This model was constructed by neural network system, and expressed some objects by vector composition in the input layer. And, we expressed a driver's information processing using the factor analysis to the model, and analyzed about influence of the environmental information. At the result, this analysis expressed the processing quantitatively, and showed about the influence.
