SUMMARY:

The study investigates the application of the iRAP (International Road Assessment Programme) methodology in a highway concession project in Paraná, Brazil, aiming to evaluate the effectiveness of road safety countermeasures and their cost-benefit relationship. The concession of highways to private initiatives has been adopted by the public sector as a solution to improve management, maintenance, and road safety, especially in the context of budget constraints. The iRAP methodology, recognized for its rigor in risk classification and intervention recommendations, was applied to a 500 km stretch of highways, selected based on criteria such as logistical relevance, traffic volume, and accident history. The analysis consisted of coding infrastructure characteristics to generate star ratings, allowing for risk prediction and the projection of cost-benefit scenarios for proposed measures. Using the Pearson Chi-Square test, significant correlations were identified between high-risk areas classified by iRAP and accident frequency. The results indicate that incidents occur more frequently in high-risk areas, and the suggested countermeasures, such as physical barriers, improved signage, and shoulder adjustments, are effective in reducing both the frequency and severity of accidents. These measures align with the concept of "forgiving roads," promoting significant improvements in road safety and mitigating risks of head-on collisions and pedestrian accidents. Financial analysis demonstrated that investments in road safety, as proposed by the iRAP methodology, generate substantial long-term economic benefits, outweighing the intervention costs. Furthermore, the research highlights the importance of data quality, as the effectiveness of countermeasures directly depends on the accuracy of information regarding road conditions and accident history. Thus, the study proposes a more assertive economic modeling of concession contracts and the incorporation of safety criteria in Road Exploration Programs (PER), enabling a replicable and sustainable model for infrastructure projects in Brazil.
