Abstract
QALY (Quality Adjusted Life Years) and DALY (Disability Adjusted Life Years) are units of measure that can be used to express the consequences of (traffic) injury. As yet, these measures are rarely used in road safety research and policy, but in other fields QALY and DALY are much more common. This study, which consists of a literature study and some interviews with policymakers and researchers, discusses the 'state of the art' of both concepts and investigates their usefulness and added value for road safety research and policy.
