The Global Designing Cities Initiative (GDCI), a program of the National Association of City Transportation Officials (NACTO),  in partnership with the International Road Assessment Program (iRAP) published recently a new Document titled “iRAP Star Ratings of NACTO-GDCI’s Global Street Design Guide”. Released in 2016, the Global Street Design Guide has served as a blueprint for safer and higher-performing streets, and as a tool for addressing the 1.35 million road accident deaths and up to 50 million injuries that occur each year as a result of poorly-designed roads. As such, iRAP’s Star Rating methodology offers a useful framework for validating the tools and transformations featured in the publication.  pdf5
