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 iRAP tool is available as part of iRAP’s free-to-use toolkit making safer road design accessible for all, including low- and middle-income countries.

It is available for free for ViDA Creator account holders.

The iRAP SR4D tool was developed by iRAP with support from the World Bank’s Global Road Safety Facility.

Watch this short video on how to access Star Rating for Designs through ViDA. All the iRAP road survey data gathered around the world, is processed through ViDA, our central database.
