Analysis Of Road Geometric Standards In Hilling Areas Using Bim

Roads in hilly areas with relatively complex geographic and topographical conditions, difficult terrain, non-standard road geometries, causing not all areas to be well connected, and causing low regional accessibility, therefore determining the road geometry is very important for driving comfort. Road geometric planning is focused on horizontal and vertical alignment so that it can fulfill basic road functions that provide optimal traffic flow comfort according to the planned speed. This study aims to determine the geometric standard of roads in hilly areas using a combination of conventional and BIM methods, identify road geometries that do not meet the standards, then redesign them. It is known that there are some geometric points of the road that do not meet the horizontal and vertical alignments, so it needs to be rearranged. The results of the analysis and rearrangement in this study can be used as a reference for road geometric improvements so that accessibility between regions can be improved.
