Since 2006, we have made a progress on ‘driving-space improvement project for safety and comfor’ at Metropolitan Expressways. The road marking 'Optical Dots' were installed on a two-lane highway in downstream at Bijogi Junction zone of Saitama Omiya line in Feb. and Sep.'08. As we reported at ITS-Sympo'08, the result of reduction in speed was observed soon after then. We report the experiment about the influence to drivers’ visual perception and action by using Driving Simulator generating Virtual Reality of highway.
