Star Rating for Designs (SR4D) is a process and evidence-based programme of applications informed by the iRAP Methodology which enable the objective measure, 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.
SR4D enables road engineers and designers, municipalities and road authorities, funding agencies and governments to make roads safer.
Ensuring the safety of a road design before it clears the design phase directly equates to lives and serious injuries saved on the street. Despite knowledge and free tools to improve design safety, unsafe 1- and 2-star roads are still being built.
SR4D strengthens the road safety audit process, complementing it with an objective and repeatable qualification of road user risk (without the need for a high level of experience), and supports the wider potential of Star Ratings as a safety performance metric and maximised safety in road infrastructure investment.
SR4D will be essential to supporting countries to achieve the United Nations Global Road Safety Performance Targets, especially Target 3 to ensure all new roads are built to a 3-star or better standard for all road users.

Road Designers Consultation Group
A Star Rating for Designs Road Designers Consultation Group was established in May 2022 to provide a road designer’s perspective on the development of the SR4D program and tools. See the Group’s Terms of Reference here. Advice and feedback may span all aspects of SR4D, for example:
– The road design process and how software is used
– The effectiveness of SR4D tools and development needs
– Training and accreditation
The Group comprises 18 experts with extensive experience in road design and SR4D, drawn from the private sector, public sector and NGOs, from each region of the world. Their guidance will help inform the development of the Star Rating for Designs tool and global advocacy and action to achieve iRAP’s vision for every road design to have a Star Rating.
