The transportation community has begun to recognize the need for comprehensive performance measures for traffic safety. Using a single crash rate inevitably neglects other aspects of traffic safety. This study proposed a traffic safety index combining three dimensions of traffic safety (fatality, injury, and crash) from two perspectives (person and road) and applied the index to project a comprehensive traffic safety picture of South Korea. The proposed index employed the approach used for the human development index of the United Nations, and its confidence interval was estimated on the basis of moving variance. The proposed index and its confidence interval were shown to be useful in evaluating overall safety performance of the entire nation over time. The index can be tied to a macrolevel safety plan or policy in setting a goal, and it is not limited to South Korea but is applicable to any nation or large area as long as valid historical safety data have been maintained.
