A large number of persons are killed or seriously injured in road traffic every year, and this is a great public health problem. The development of different traffic safety measures is proceeding rapidly, and it is of importance that the knowledge is spread and applied. In order to gain information on the state of the art within the traffic safety area the Swedish National Road Administration (Vaegverket) has commissioned universities and research institutes to carry out a number of literature surveys covering different parts of the area. This literature survey concerns the planning of the road transport system development. Since this is a very extensive area to cover, certain limitations have been made. The focus is primarily on investigating the concepts of trafficability, accessibility, environmental impact and traffic safety but also measures and methods used for describing the influence of road surface condition on these.
