FSI saved by iRAP protocols in 74 countries.

ObjectiveRoad traffic crashes cause 1.19 million deaths and millions more injuries annually. The persistently high burden has drawn attention from national and international stakeholders worldwide. Unsafe road infrastructure is one of the major risk factors for traffic safety, particularly in low- and middle-income countries.MethodsAiming to eliminate high-risk roads in all countries, the International Road Assessment Programme (iRAP) developed a robust and evidence-based approach to support country transportation agencies.ResultsThus far, the iRAP protocols have been used to collect 1.8 million kilometers of Crash Risk Mapping and 1.5 million kilometers of Star Rating and FSI estimations in 128 countries. Deploying an observational before-and-after (or pre-post) study design, this report estimated the fatal and series injuries (FSI) saved through use of the iRAP protocols. The study is based on 441,753 kilometers of assessed roads from 1,039 projects in 74 countries. Our results show that the implementation of iRAP’s proposed countermeasures saves about 159,936 FSI annually. Throughout the lifetime of the implemented countermeasures, a total of 3.2 million FSI could be saved.ConclusionWhile quantifying the success of the iRAP protocols, our results suggest an opportunity to save many millions more lives on the roads through expanding iRAP implementation to more regions and countries.

研究背景 道路交通事故每年造成119万人死亡，另有数百万人受伤。这一持续高企的伤亡负担已引起全球各国及国际利益相关方的高度关注。不安全的道路基础设施是影响道路交通安全的主要风险因素之一，在中低收入国家尤为突出。研究方法 为消除全球各国境内的高风险道路，国际道路评估计划（International Road Assessment Programme, iRAP）开发了一套严谨且基于实证的评估方法，以支持各国交通管理机构开展道路安全工作。研究结果 截至目前，iRAP评估规程已在128个国家完成180万公里的事故风险测绘，以及150万公里的星级评级与致命与重伤（Fatal and Serious Injury, FSI）估算工作。本报告采用前后观测（或称干预前后）研究设计，基于74个国家1039个项目的441753公里道路评估数据，估算了应用iRAP评估规程所挽救的致命与重伤案例数。研究结果显示，推行iRAP提出的安全改善措施后，每年可挽救约159936例致命与重伤案例；在安全改善措施的全生命周期内，累计可挽救320万例致命与重伤案例。研究结论 本研究在量化iRAP评估规程应用成效的同时，结果表明，若将iRAP评估规程推广至更多地区与国家，有望进一步挽救数百万道路使用者的生命，显著降低道路交通事故的伤亡负担。
