Outline of Final Research Achievements

The quantitative measuring and evaluation were carried out in this study for the direct view of road intersections and indirect view of them by the intersection convex mirrors. The authors proposed a noncontact method measuring the position and angles of a convex mirror. And a shape of the road of the drivers' view at an intersection, which was named "viewing area" was defined by the authors. The variation of change of the viewing area by entering the intersection affects the safety passing through intersections so much that the authors made a method estimating the safety of the intersections and calculation of the size of the viewing area. In addition, a method which can reduce the drivers' intention entering merely to pass through community roads in the residential area was proposed by the brain waves of the subjects on the driving simulator. The study showed the versatile quantitative evaluation methods to find the factors of unsafety and the useful safety measures.
