Ratings as intermediate outcome targets

Although not presently in use, targets could also be set using safety rating data. For example, a target could be set to increase the percentage of cars with five star Euro NCAP ratings in the national fleet or to increase the percentage of vehicle mileage on roads that fulfil EuroRAP four star ratings in rural areas by a specified amount over a given time period. The approach to achieving this is likely to be a combination of mass action implementation of effective safety measures, and major upgrading of some parts of the network to a higher standard. EuroRAP thus provides a basis on which to assess both what risk levels are desired, and what changes to the road infrastructure are needed to provide these levels [20].
