The map contains collision data for the latest 5 year period which is currently 1st January 2012 to 31st December 2016. Each year’s collision data is released around May, once the data has been fully collected, validated and verified by the Department for Transport. More about collection/release of data.
Not every single collision that occurred in the Devon County Council area will be recorded on the map; if a collision did not result in personal injury and/or was not reported to the police it will not be recorded in this dataset as per Department for Transport guidelines. More information about this collision dataset (called Stats19 data) is available at GOV.UK – Road accidents and safety statistics guidance, please also see our FAQs page.
If you think that a collision has been plotted incorrectly then please let us know at firstname.lastname@example.org. The locations of the collisions you see on the map are recorded by Devon & Cornwall Police, and we do apply our own additional validation checks that include scanning for plotting errors however we are unable to verify the location of every single collision record that we receive from the Police.
