EVALUATION OF ROAD SURFACE BY BRI CALCULATED FROM POINT CLOUD DATA OF ACTUAL CYCLE PATHS

Abstract

 Until now, the BRI (Bicycle Ride Index) has been used to evaluate road surfaces on a single measurement near the outside line of the roadway on which bicycles travel. However, since bicyclists ride over a certain width of roadway, it is necessary to evaluate the road surface not only linearly but also areal-wise. In this study, we evaluated bicycle paths by BRI using point cloud data acquired by MMS (Mobile Mapping System) and calculated BRI by extracting road surface profiles from the point cloud data in order to examine the usefulness of MMS. As a result, the road surface properties in the areas with high BRI values were confirmed to be unique, and it was clarified that it is possible to evaluate bicycle paths by calculating BRI using the road surface profiles extracted from the point cloud data acquired by MMS.
