The Royal Automobile Club of Queensland (RACQ) commissioned an AusRAP assessment of Peak Downs Highway based on the iRAP protocol. The purpose is to provide star ratings and investment levels for improved safety outcomes on Peak Downs Highway. The star ratings provide a measure of the safety performance of the road infrastructure. The total road length assessed is 267 km. Out of this, about 5% is rated as 1-star, 54% as 2-star, 40% as 3-star and 1% as 4-star for car occupants.
AusRAP star rating is a methodology, based on the iRAP protocol with an associated web-based tool, ViDA, used to assess the safety potential of roads, provides star ratings and to develop road safety investment plans. The star ratings provide a measure of the safety performance of the road infrastructure. The star ratings are derived from a Star Rating Score (SRS) based on road safety
inspection data and the extensive real-world relationships between road attributes and crash rates.
