Assessing speed enforcement policy measures by analyzing multi sustainability criteria

Abstract

This paper discusses how the sustainability assessment is generally used to identify the unsustainable effects of policy measures, such as sustainable transport policy strategies. Still, sustainability effects of road traffic safety policy measures are insufficiently studied. This paper assesses the sustainability of speed enforcement policy measures on highways. A multicriteria evaluation framework, containing social, economic and environmental assessment criteria, evaluates different speed enforcement policy alternatives. The framework determines how the policy alternatives meet the criteria and ranks the policy alternatives according to their sustainability. The results presented in this paper show that intelligent speed enforcement strategies are more sustainable than automatic and manned speed enforcement strategies. Multicriteria have proved to be very useful for assessing sustainability.
