Abstract: Increasing social, economic and ecological impactof motorised mobilityrequiresanidentification of sustainable mobility policies, as well as a clear evaluation of the impact of such measures. Still, there is a lack ofpractical orienteddecision-supporting instruments to assist decision-makersin the sustainability assessment of mobility policies. The present paper proposes a pragmaticassessment framework, includingproceduralSustainability Assessment (SA) and Analytic Hierarchy Process (AHP) constituents,to determine the sustainabilityof traffic safety policies.Thecompositeframework formatprovides decision-makersnotonly technical details ontheassets and the limitations of the alternative policies, but offers procedures to reach and implementassessment decisions as well. The paper applies the pragmatic framework for the specific case of the present 30-km/h scenario in the Brussels’ pentagon, of which the sustainability performance is compared to four general 30-km/h policy alternatives, i.e. 30-km/h speed regimes, speed reducing devices, (re-)constructing roads and junctions and (re-)constructing active mode infrastructure. Results show that the sustainability performance of the Brussels’ pentagon scenario can be enhanced by complementary active mode infrastructure and speed reducing devices, which benefit traffic safety, incite emission-free mobility and provide access to a larger quantity of travellers. The proposed framework bridges the gap between policy impact assessment framework design and use, while specifying the assessment attributes according the basic dimensions of sustainable development. Both are beneficiary fordecision-processes towards sustainability.
