Using the International Road Assessment Programme (iRAP) methodology, road safety infrastructure changes and safer speeds within more than 1,000 infrastructure projects have prevented almost 700,000 deaths and serious injuries in 74 countries since 2016, according to a new paper with Johns Hopkins University published in PLOS One. This study is the first to measure the impact of road projects financed by governments, development banks and private-sector road operators around the world using the iRAP methodology and tools.
