This paper provides some detail of the project undertaken for the Roads and Traffic Authority, NSW in Australia and defines the approach and method for the derivation and computation of rural roads crash rates for various stereotypes (roadway cross sections with similar design characteristics) and the means for the provision of an extensive database/spatial database of road stereotypes that are apparent throughout the State of NSW. The project tasks were: 1. To determine typical values for rural crash rates of various stereotype roads; and 2. To produce a spatial database and model that will allow easy future extraction and update of various stereotypical crash rates. The outcome of this project provides a strategic model that can successfully “predict” the expected crash rate ranges, for a specific road stereotype and for a combination of different road attributes.
