Star Rating for Designs (SR4D) is a process and evidence-based programme of applications
informed by the iRAP Methodology. It enables the objective measurement, and improvement,
of the level of road safety ‘built in’ to a road design for vehicle occupants, motorcyclists,
pedestrians and cyclists, before the commencement of civil works.
