How SR4D works

Star Rating for Designs can be incorporated as part of a road safety audit or completed independently. Star rating of a design, using the SR4D tool, or through other iRAP processes, can be performed by any suitably iRAP trained road safety practitioner. The design drawings together with other key project fundamentals such as expected traffic volumes and speed estimates can ensure the star rating of a design can be completed from the desk-top with local knowledge.  Road safety auditors are well placed with the skills needed to star rate designs.

Star Ratings are now being used by many agencies to ensure that safety is built-in to designs for upgrades and new roads prior to construction.

By providing a means of objectively measuring the impact on risk of various design iterations, the Star Rating design process helps to harness the potential of designers to find creative solutions to challenging safety problems.

For governments and development banks, the process opens the opportunity to set performance-based targets for vehicle occupants, motorcyclists, pedestrians and bicyclists that not only improve safety but create a high level of transparency and accountability.

The Star Rating design process has been successfully used in countries such as Australia, New Zealand, Moldova, Qatar and India, in conjunction with existing mechanisms such as Road Safety Audits and highway design standards.

iRAP has developed standard specifications to undertake a Star Rating of a Design that can be included in your project and a trusted network of trained Design Star Rating suppliers around the world is also available.

If you need help iRAP can assist in the direct planning and procurement for a star rating for designs assessment.
