Ranking Road Safety Hazardous Locations in Nepal : A Case Study of Kalanki (Ch.10+600) – Koteshwor (Ch.20+994) Road Section

Abstract

In Nepal, there are many emerging towns and cities due to rapid urbanizations which have arose issues of increased traffic density resulting in frequent road crashes like in Kalanki Koteshwor Ring Road Section. This study presents six stage methodological framework for ranking road safety hazardous locations based on Analytical Hierarchy Process (AHP) and field survey (condition rating) to identify the hazardous locations of Kalanki Koteshwor Road Section by weighing the safety parameters of the road section and calculating the Safety Hazardous Index (SHI). The results show that road section ’Ch.12+600 km to Ch.14+600 km’ is ranked as the most hazardous location with SHI 12.38 and ’Ch.10+600 km to Ch.12+600 km’ is ranked as the least hazardous location with SHI 9.30 among the five road sections considered. This ranking can be a prompt technique for prioritizing the treatment of the hazardous locations keeping available road safety budget in mind.
