Gloucestershire County Council is recognised by the Department for Transport (DFT) as the local processing authority for road accident statistics.

This is a role performed on behalf of Gloucestershire Constabulary and it involves collecting from their officers, selected details of every injury accident they attend.

Each report is carefully checked using a computer-generated map of the county. Details like road type, road number and grid reference are especially important. The data is transferred to the Department for Transport to assist with the compilation of national road casualty statistics.

As a result, the team has access to a database dating back to 1983 and containing over 100,000 records, which can be used together with the computer mapping system to monitor risk, accident clusters and concentrations on the highway network.


In addition to identifying accident clusters and “hot spots”, the database can also be used to:

  • Determine the nature and characteristics of accidents along routes
  • Help prioritise spending on road improvement
  • Ensure that proposals with road safety benefits receive priority consideration
  • Identify speed related accident clusters where safety cameras may be beneficial


Please note that Gloucestershire Constabulary changed their method of reporting injury collisions in 2015 and as a result there has been an increase in the number of serious casualties in Gloucestershire. 

The Department of Transport is investigating nationally the effect of this change.  Until the results of the investigation is known the quarterly reporting of all killed and serious injury (KSI) figures should be viewed with caution.
