The need for conducting research on decision-making processes as regards investments in roads and lanes has been paid attention to by the Swedish Transport and Communications Research Board (KFB) and the National Swedish Road Administration in the late 1990,s. This study delivers its contribution by accounting for and analysing the decision-making process that resulted in wire railings of central reserves being set up and 2 + 1 lanes being built on the European Highway No. 4 to the north of Gävle. By means of documents, press cuttings and interviews, light is being thrown on the development, from the establishment of the Vision Zero to the consequences of the project in the form of a new type of wire railings. Factors such as formulation of problems, search for options and assessment of consequences are accounted for. Ways and means to organise the process, external interested parties’ influence and the participants’ roles, activities and attitude development are highlighted. This process submits to testing an entirely new design of roads and puts it into practice. The process of acquiring experiences is in the centre of attraction. It applies to both the feasibility study, including the problem of convincing sceptics and gaining their acceptance, and the experience of achieving a substantial innovation in the road safety area. The study emphasises both the specific aspect of this case and the generally applicable with road planning and accordingly infra structure. The need for further development of know-how as to a theoretic and empiric knowledge bank of decision-making processes is additionally highlighted.
