Within sustainability assessment of policy measures, possible social, economical and ecological effects are measured before the eventual policy decision is made. This dissertation applies several evaluation criteria, for each dimension of sustainable development on traffic safety measures, based on an identification framework for sustainable development.


Approximately 20- till 30% of all drivers exceed the speed limit on regular basis, making excessive or inappropriate speed responsible for 30% of all causalities. Because excessive speed effectuates clear action in each of the three behaviour influencing traffic safety pillars (3 E’s), a policy measure for each pillar will be subjected to the assessment. This paper elaborates a sustainability assessment for the ‘Engineering’ pillar, completed in an infrastructural way. Possible impacts of the operational policy measure ‘(re)designing 30 km/h roads’ are synthesised, supported by published sources. 


The Goal Oriented Indicator Framework, as a tool for integrated assessment, is developed to monitor unsustainable effects of new policy measures. Immediate identification of policy objectives and the associative processes to achieve these policies are the main qualities of the framework. The generic themes ultimate goal, means and methods constitute the functional relations of the model. Sustainability indicators measure each generic theme in order to achieve the ultimate goal. Eventually, the monitoring tools should direct traffic safety measures towards sustainable development.
