【 摘 要 】

This paper simplifies the road improvement option selection process within Safer Road Investment Plans to make it more suitable for strategy analysis or road networks. This simplification is needed to reflect the management function in the road management cycle that differs from the iRAP (International Road Assessment Programme) methodology. It studies Road Safety Policy Tools embodied in the iRAP, designed to increase road safety, through a review of the literature, with a focus on Safer Road Investment Plans. Based on the analysis of road improvement option selection processes and data integration, the paper develops a generic countermeasure model to assess road conditions and to screen road-works. In addition, the model was applied to two case studies of strategic roadwork plans. The project-level results were obtained through deep analysis of road attribute data. The results showed that the generic countermeasure model could lead to similar treatment plans using similar budget, which demonstrated its feasibility and opens up possibilities for its further extension.
