Identifying the most hazardous intersections is essential in road safety management to prioritize road safety interventions. The equivalent property damage only (EPDO) measure is highly recommended because it reflects the severity levels of road crashes. The main challenge in using this measure is the estimation of crash cost. In Iraq, there has yet to be any previous attempt to estimate the crash cost according to their severity level. Therefore, this research aims to identify the most hazardous intersections according to a developed EPDO for Iraq conditions. The methodology of the work is divided into two stages. The first stage is an estimation of the crash’s cost. Three methods have been used for gathering crash cost data: the willing-to-pay approach for estimating the life quality cost, the human capital for finding the production loss costs, and the restitution approach for estimating medical treatment costs, vehicle damage costs, and administrative costs. In the second stage, the EPDO (Iraq) is developed. The results show a significant correlation between the rank of intersections according to the EPDO scores and crash frequency.
