Abstract
This paper deals with the importance of ‘Driving Behavior models’ from the points of view of academic interests and engineering aspects. For academic interests, the mechanism of occurrence of capacity bottlenecks at basic freeway segments, which occur around sag sections or entrance of tunnels, should be clear. From the aspects of engineering, it is important to find countermeasures for such bottleneck phenomenon by traffic operation, road design, or future technology like Advanced cruise-assist Highway Systems. In this paper, reviewing the former driving behavior models, especially car-following behavior models, including man-machine model in the field of control theory, the future research needs for car-following models to analyzing bottleneck phenomena at basic freeway segments are summarized.
