Descriptions of the Measures

The aim of this measure is to ensure that roads and roadsides are becoming safer for road users.

The report determines the number of crashes with reported Fatal and Severe Injuries from the Crash data for the previous 10 financial years for your network, Peer Group , Region and the Nation .

The previous 10 financial years of crash data starts with the last complete Financial Year  for each RCA included in the report or groups (Peers, Region, Nation). The data is grouped by financial years beginning 1 July.

Crashes are allocated to carriageways on the location of the crash. If a crash is located at the start of one road section and the end of another road section, it will be allocated to the road section which starts where the crash is located.

The number of crashes with serious injuries and fatalities within the classification is divided by the number of years of data (the difference between the first crash in the classification and the last up to a maximum of 10 years) to get a number per year. This is then divided by the Length of Network within the classification to calculate the Collective Risk.

 An exclamation mark indicates the crash sample length is below 65kms.
