Análise de segurança viária na PRC 280: estudo de caso no trecho entre Pato Branco - PR e Mariópolis - PR

Abstract

Traffic accidents are one of the leading causes of deaths and serious injuries in developing countries like Brazil. Despite various initiatives over the past decade, the global mortality rate from accidents has remained unchanged, indicating the need for greater investment in road safety. In order to prevent new accidents with serious and fatal injuries, it is necessary to adopt proactive road safety management approaches. iRAP, the International Road Assessment Programme, is a method that proposes inspecting roads by evaluating their infrastructure characteristics every 100 meters. The program generates a road safety rating and an investment plan, identifying necessary countermeasures to proactively address the locations with the highest risk of serious accidents. In applying the iRAP method, the most critical segments were identified and priority investments of 109 million reais were determined. This initiative could prevent around 105 fatal or serious injuries over a 10-year period. The application of iRAP has proven effective for analyzing the road safety of rural highways by experienced professionals, showing great potential to support road safety projects on the country's roads.
