This map shows the statistical risk of death or serious injury occurring on Britain’s motorways and A roads for 2006-2008 covering 45,000km in total. The risk is calculated by comparing the frequency of death and serious injury on every stretch of road with how much traffic each road is carrying. For example, if there are 20 collisions involving death or serious injury on a stretch of road 5 miles long that carries 10,000 vehicles a day, then the risk is 10 times higher than if the road section has the same number of collisions but carries 100,000 vehicles. Some of the roads shown have had improvements made to them recently, but during the survey period the risk of a fatal or serious injury collision on the black road sections was more than 10 times higher than on the safest (green) roads.
