The iRAP Star Rating Methodology and Road Safety Inspection (RSI) have similar objectives but different approaches. As part of the Central Asia Regional Economic Cooperation (CAREC) program and with the support of the Asian Development Bank (ADB), a methodology for assessing safety condition of road sections was developed by combining iRAP Star Rating Methodology and Road Safety Audit called Star Rating for Road Safety Audits (SR4RSA). The results of the assessment using iRAP Star Rating Methodology show that Kopo – Soreang road section still has a road segment with a Star Rating value below 3 for all road users, with a value of fatality estimated at 58 annually. Common safety concerns found in Kopo – Soreang road section based on the results of the Road Safety Inspection (RSI) are delineation, intersections, curvature, roadside severity objects, pavement surfaces defect, and vulnerable road users facilities. Using SR4RSA Methodology, a series of countermeasures from the iRAP Star Rating Methodology are adjusted to Road Safety Inspection Methodology resulting in 28 countermeasures that can be applied to Kopo – Soreang road section and a Star Rating value of 3 and above for all road users with a reduction in fatality estimation value of 49,91%. After countermeasures have been implemented, the Star Rating value of vehicle occupants resulted in a rating of 5 stars that is higher compared to other road users Star Rating. This indicates that the implemented countermeasures are more focused on vehicle occupant’s safety. The result of this study shows that SR4RSA Methodology can be used to address the objectives of “RUNK LLAJ” in supporting the Global Plan Decade of Action for Road Safety 2021-2030.
