Casualty Statistics

Your community can access information about Gloucestershire’s casualty statistics and facts, detailed information about safety schemes that are being introduced and why, as well as the monitoring of accidents. Further down the page are links to all of the statistics.

Gloucestershire County Council (one element of the Road Safety Team) is recognised by the Department for Transport 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. Once a month 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.

The mapping system can be used to study clusters of accidents by any of the characteristics stored on the database. This information is invaluable in our road safety life skills planning, and campaign work.

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, and.
  • Identify speed related accident clusters where Safety Cameras may be beneficial.

2016 Casualty statistics

In 2016 there were 851 collisions which resulted in 1165 casualties, of these 279 were killed or seriously injured (KSI). In comparison with 2015 the number of slight injuries have decreased by 1% and the KSI’s have shown an increase by 25%.

Please note that a change in the method of reporting injury collisions has resulted in 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.

National Collision Statistics – 2016


Reported road casualties in Great Britain, main results 2016 can be found by clicking here.


2016 reported road casualties, compared with 2015 show:

  • an increase of 4% in road deaths to 1,792
  • a decrease of 3% in casualties of all severities to 181,384
  • vehicle traffic levels increased by 2.2%



Every year the County Council’s Accident Database is analysed to identify locations where a high number of accidents are occurring. Each location is assessed generating a score based on set criteria in line with our Local Transport Plan Targets.

In summary this calculation is based on: The number of users against the number and type of casualties occurring in a 3-year period, showing us a road users ‘exposure to risk’.

Although this is a broad-brush approach to collision identification it is very effective in identifying the majority of problem sites around the County, we also carry out specific causation investigations which allow us to look in to other areas such as accidents; on bends, in adverse weather, involving animals and many more.

The role of the Accident Investigation Engineer is to interrogate this information, and investigate/identify any feasible remedial measures that could be achieved, using the road safety revenue budget or capital programme funds.

Road Safety Schemes are put forward in to the County’s Priority Assessment System, and if successful, developed and installed by capital funding.
