Road crashes are among the main causes of death in the world. In order to minimize the number of crashes, suitable safety countermeasures must be installed at road networks. In the City of Duhok located in the Iraqi Kurdistan Region, the number of registered vehicles has increased dramatically due to the economic growth and stability after 2005, which resulted in significant increase in vehicle crashes. This paper aims at introducing the concept of the Crash Modification Factors (CMFs) as an important analytical tool on measuring the road safety and suggesting suitable countermeasures that might help in improving the safety through the reduction of crashes. A case study of Zari land intersection in Duhok City is presented in the paper. Crash data used in the analysis are obtained from the Duhok Directorate of Traffic Police for the years 2017, 2018, and 2019. The expected number of crashes at the intersection is calculated using the predictive method of the Highway Safety Manual, and three safety countermeasures are suggested to enhance the intersection safety. Results show that applying the suggested safety countermeasures would decrease the number of crashes by 42% from 12 crashes/year to 7.0 crashes/year. This implies that the CMFs can effectively assess the safety situation at any intersection or road segment, which can be addressed by the installation of proper safety countermeasures to improve the safety at the site.
