REVIEW THE HIERARCHY OF HAZARD CONTROLS TO URBAN ROAD SAFETY AND SUSTAINABLE MOBILITY

Governments globally have endorsed Vision Zero, declaring that no person should be killed or permanently injured on public roads. Concurrently, the wider social, public health, and environmental implications of urban structure and transport choices have gained intense policy attention, as cities aim to transition toward sustainable accessibility. This is especially the case as research reveals a range of counter-intuitive road safety dynamics; many narrow approaches to road safety management appear to trigger adverse risk compensation and negative externality effects, potentially running counter to broader sustainability goals. Recognizing the urgent need to integrate road safety with broader urban sustainability measures, this synopsis presents a review of road safety literature using the established Hazard Control Hierarchy. In doing so, we identify and categorize opportunities to more effectively combine Vision Zero with broader sustainable accessibility policy objectives. We synthesize the literature against the Hazard Control Hierarchy to devise a framework to more effectively integrate the work of professional disciplines which shape the safety and sustainability of the urban built environment.
