Accidents Analysis of Kandahar-Spin Buldak Highway in Afghanistan

Abstract

The study aims to identify and prioritize the accidental blackspots locations on Kandahar – Spin Buldak highway located in Afghanistan. The hazardous locations (blackspots) are identified by the APW (Accident Point Weightage), EPDO (Equivalent Property Damage Only), and RQC (Rate Quality Control) methods. In the first step;APW and EPDO methods identified Km 7th, Km 20th, Km 47th, Km 62nd and Km 90th as blackspot locations on Kandahar – Spin Buldak highway, however, integrating all three methods (RQC, APW and EPDO); the Km 7thand Km 20th are recognized as critical hazardous locations alongside this highway. While practically and theoretically high number of crashes occur in locations where there is higher AADT,surprisingly, this paper found critical blackspots locations alongside Km 7th and Km 20th segments of the highway(havingalmost equal and less AADT in comparisonwith 47th, 62nd and 90th Km).
