Safe system approach becomes the prevalent concept on the success of several road safety programmes. Opposing the traditional perception that human errors lead to road crashes, safe system approach emphasizes the responsibilities of all relevant parties to road crash. The local governments are no exception. However, there is no competition between them since they are entitled to get monopolistic power to implement road safety policies. It deters their proactive actions for safer road system. The study develops the Road Safety Performance Indicators (SPIs) to evaluate and compare the performance of local government. SPIs are measurement to capture the intermediate steps between actions and final outcomes in term of road deaths and casualties. The proposed index, a set of indicators, consists of four categories to: (a) institutional management, (b) intervention, (c) Intermediate outcome and (d) final outcome. It is applied to metropolitan areas and provinces in Korea showing the highest road fatalities rate among OECD member countries in 2015. It will be converted the road safety performance scores to show the level of safe system of local government in Korea. As the level of road safety system and road death varies considerably, it will provide useful information to which part is more important to achieve final results: reduction of road fatalities, serious injuries and crashes.
