Road traffic accidents still become major problems for Indonesia causing more than 25,000 deaths per year. One of the challenges faced in making road betterments is how to identify and prioritize black spots with minimal accident data. This study offers an innovative approach to combine Equivalent Accident Number (EAN) with other road and traffic parameters which have potentials to cause accidents: average daily traffic, road pavement condition, turning radius, road grade, shoulder width, roadside hazards, and safety facilities, called Road Safety Survey Value (RSSV). The approach was successfully implied on National Roads Southeast Sulawesi Province, showing more accurate ranking of 15 black spots to be treated than the EAN Method.
