| Outline of Final Research Achievements |
Existing car-following theory that can describe traffic flow dynamics is difficult to be used in traffic-control device design, such as enhanced road markings capable of properly controlling the first vehicle's speed, due to a limitation that each speed change of the second and subsequent vehicles except the first one can only be described in the theory. Therefore, this research rebuilt the theory considering the first vehicle's speed in order to contribute the design of proposed transverse and lateral road markings, through incorporating a mechanism in which the first vehicle's driver visually perceives the vehicle speed from array patterns of such markings and chooses a driving speed, into the existing car-following theory. Standards of the array patterns of the markings corresponding to the driving environment were proposed in this research in terms of speed perception of the leading vehicle's driver and collision risk of the following vehicle.
