Abstract
This paper presents the development of the modeling of human driving behavior based on mode segmentation. The transition between modes can be regarded as a decision making in the human behavior. In this paper, two kinds of decision are considered under a hierarchical structure. First one is a "intentional decision" which is caused by the change of intending task. Second one is a "reflective decision" which is made to accommodate with the change of situation. The former is modeled by the logistic regression model while the latter is modeled by the discrete/continuous hybrid system (HS) model. The usefulness is verified through application to the driving behavior on the express way.
