Abstract
The purpose of this study is to compare the effectiveness of road safety features by spatial scope Spot & Section-based safety Improvement project. Empirical data was collected from black-spot study of Jeonbuk and "Traffic Safety Improvement Project on National Highway 17". Evaluation model of effectiveness was developed by using Empirical Bayes (EB) method. And Relative Effectiveness was measured by Odds Ratio. The result indicates that Section-based safety improvement was $7.09{\sim}77.27%$ more effective than the spot-based. It means that section-based improvement projects should be expanded while considering the characteristics of the section in spot based improvement.
