Federative Republic of Brazil iRAP Pilot Technical Report : Federal Highways

Abstract

part of efforts to curb road deaths             and serious injuries, the World Bank Global Road Safety             Facility (GRSF) invited the International Road Assessment             Programme (iRAP) to work with the National Department of             Transport Infrastructure (Departamento Nacional de             Infraestrutura de Transportes, DNIT) to assess the safety of             Brazilian roads. During this second assessment of Brazilian             roads, approximately 3,400km of roads were assessed. This             technical report describes the road assessment project and             includes details on data collection, the methodology used             and a summary of the results. The infrastructure-related             risk assessment involved detailed surveys and coding of 50             road attributes at 100 meter intervals along the network and             creation of Star Ratings, which provide a simple and             objective measure showing the level of risk on the road             network. The star ratings show that 1 percent of road length             is rated as 5-star, 9 percent is rated as 4-star, 58 percent             is rated as 3-star, and the remaining 32 percent is rated as             2-star and below for vehicle occupants. For motorcyclists,             no roads were rated as 5-star, only 3 percent of road length             is rated as 4-star, 47 percent is rated as 3-star, and the             remaining 50 percent is rated 2-star and below. For             pedestrians less than 1 percent is rated as 4-star and             5-star, 2 percent is rated as 3-star and the remaining 13             percent is rated 2-star and below. For bicyclists less than             1 percent is rated as 5-star or 4-star, 5 percent is rated             as 3-star and the remaining 14 percent is rated 2-star and             below. The project also involved the creation of a Safer             Roads Investment Plans, which draws on more than 90 proven             road safety treatments, ranging from low cost road markings             and pedestrian refuges to higher cost intersection upgrades             and full highway duplication.
