EVALUATION OF VISIBILITY IN THE INTERSECTION USING POINT CLOUD DATA BY MOBILE MAPPING SYSTEM

Abstract

 There are many blind intersections to cross. The necessity of improvement of blind intersection is judged by transport engineers. The authors executed the evaluation of intersection by the quantity of visibility using three-dimensional point cloud data acquired by Mobile Mapping System. As a result, the visibility was expressed by the rate of Invisibility space at viewpoints, along the road.
