Improvement in Geometric Design of SH-18: A Case Study

In the present study, is primarily to develop a geometric design consistency analysis criterion for 2- Lane horizontal curves for 2-Lane Rural Highway that applies to Indian conditions. Road accidents result in significant social and economic issues. Studies targeted at geometrical design and safety aim to enhance road design and also to eliminate dangerous locations that can cause accidents. The consequences of design parts like horizontal and vertical curves, lane width, shoulder dimension, Superelevation, median dimension, curve radius, sight distances, etc. on safety were studied. Although it has been clearly shown text extremely restrictive geometrical details like short sight distance and sharp horizontal curves result in a significantly higher accident and combining these defects in geometrical elements causes a bizarrely serve accident.
