Safety Technical Output 4 - Loss of Control on Wet Roads
The number of reported serious injuries and fatalities (DSI) attributable to loss of driver control on wet roads
The aim of this measure is to reduce the number of serious and fatal injuries due to loss of control in the wet.
Injuries are recorded in the Crash table containing reported crashes and the report groups the data for the previous five financial years. Financial years begin July 1. Financial years are considered complete after details of a Crash are imported into the Performance Measures Reporting Tool for the following financial year.
Crashes are allocated to road section(s) based 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 comparative trend graph expresses the loss of control on wet roads trend as a percentage of the average crash rate for the previous five financial years, ignoring the current incomplete year. This creates a trend value that is based on the change in crash rate relative to the size of the network (average crash rate). We use this figure to allow comparison between large and small networks. This trend is shown calculated for your network, Peer Group , Region and the Nation . Negative values, shown in green, indicating a decreasing or improving trend. Positive values, shown in red, indicate an increasing or worsening trend.
If there is data for the next financial year, then this Financial Year is considered complete.
