Advanced driver-assistance systems which provide visual information to encourage safe-driving or eco-driving have attracted lots of attentions, and some functions have been already embedded in smartphone applications or car-navigation systems. Although some public road experiments have been performed both domestically and abroad, there are not so many researches and developments with respect to the systems to explicitly encourage smooth following behavior to prevent a traffic jam occurrence. Therefore, the present study aims to develop the driver-assistance system which encourages the drivers to keep a constant headway-time in order to prevent the traffic jam occurrence. This manuscript, as the first report of the study, proposes a visual information interface to display a target headway-time (2.0 seconds), a real-time information about actual headway-time, and a frame whose color and line width change according to the gap. Moreover, driving simulator experiments are conducted to verify the effectiveness of the proposed system on the prevention of the traffic jam occurrence.
