Part of the WP.29, “How it works – How to join it” series, this publication introduces methodologies that are used to evaluate the socioeconomic utility of applying key UN Vehicle Regulations for improving road safety. It presents an overview of current global road safety and vehicle safety statistics, describes methodologies that are used for assessing the impact of vehicle regulations on national road safety performance, and provides examples for their application.
Readers are introduced to procedures that are applied in estimating the impact of UN Vehicle Regulations on prevention of road traffic casualties in countries around the world, the elements of related vehicle technology effectiveness estimates, impact valuation approaches and cost-benefit analysis exercises. Based on the literature review, three country case studies are developed to calculate expected benefit-cost ratios of applying a set of UN Vehicle Regulations, which address vehicle occupant and vulnerable road users safety, over the 2020-2030 period. The publication promotes an evidence-based approach to policy making in the area of vehicle regulations for road safety
