New Interactive Crash Mapping Tool

15 December 2023

Road Safety Foundation UK have launched their new interactive crash risk mapping tool allowing users to find the routes that have improved recently and those where investment may bring the greatest returns.

The web maps show the statistical risk of a fatal or serious injury crash occurring on Britain’s motorway and ‘A’ road network for 2019-2021. This network represents less than 15% of Britain’s total road length, but around 60% of fatal road crashes, and more than 40% of serious road crashes, occur on these roads.

The risk is calculated by comparing the frequency of road crashes resulting in death and serious injury on every stretch of road with how much traffic each road is carrying. For example, the risk on a road carrying 10,000 vehicles a day with 20 crashes is ten times the risk on a road that has the same number of crashes but which 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 crash on the black road sections was more than 30 times that of the safest (green) roads.
