Abstract
Effectiveness and costs of road safety measures. This report discusses a study into the effectiveness and costs of sets of road safety measures. This information can be used in research and in policy preparation, for example ex-ante evaluations of road safety policy or outlooks, which require estimates of road safety effects and/or costs. Primarily, the study was carried out for the VVR-GIS, a software programme that can be used by municipal and provincial road authorities and by city regions to calculate the effects, the costs and the social benefits of sets of road safety measures.
