| Summary: | As 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. |
