Star Ratings for the Strategic Road Network Richard Leonard - Highways England
Highways England Network 4,300 miles of motorways and major A roads 1 billion tonnes of freight transported each year 4 million people drive on the network every day 430,000 incidents occur annually on our roads 2
Strategic Direction for Road User Safety 3
Our three imperatives Safety Customer Service Deliver the Road Investment Strategy 4
Road Safety Key Performance Indicator 5
Delivery Plan Star Rating - Commitments We will ensure that by the end of 2020 more that 90% of travel on the strategic road is on roads with a safety rating of irap 3* (or equivalent). We will ensure that the majority of those roads with 1* and 2* safety rating have improved to 3*. Alongside this we will work closely with the International Road Assessment Programme, the Road Safety Foundation and the Department for Transport to inform the development and adoption of the star rating system. 6

Safer Roads Acting before crashes and casualties occur Recognising that the road is a complex multi-dimensional system Requires systematic treatment of entire routes and networks Reducing/controlling energy exchanged in crashes Creating self-explaining and forgiving networks Acknowledging that road users make mistakes 8

Summary
Summary Strategic Direction & Plan set principles agreed, continue to develop and deliver commitments to achieve our safety ambition; Safe System the need to develop a forgiving network; Our approach builds on the irap/eurorap Model the results are challenging; We recognise that there are opportunities to improve; We need to work collaboratively to support the develop of the model and future programmes; Knowledge sharing is key what can we learn from each other. 25
