SR4D Web App

The SR4D Web App is a tool developed with support from the World Bank to assist with Star Rating designs and can be used for small to medium assessments of existing roads or road designs.

It does so by enabling the road designer to access information about the existing road conditions (through imaging such as Google Street View) and upload designs directly into the application. The SR4D Web App may also be used to Star Rate existing roads (i.e. without designs) where Google Street View or Mapillary imagery is available.

It is designed to make Star Ratings available as part of the road design process so that designers can consider the key road safety elements and the implications of a design as they undertake a road design.

The SR4D Web App is free to use and can be accessed via ViDA.
