First to publish DfT collision data

As part of the government’s initiative to release public data, and to help foster innovation, the Department for Transport has just released the 2017 road traffic collisions dataset under an Open Government License (OGL).

As this raw data is not easily understood and difficult to visually interpret, we have published it onto our CollisionMap app. This is a free service displaying a wealth of collision data overlaying open base mapping. All road traffic collisions between 1 January 2011 and 1 January 2017, which took place in Britain and resulted in an injury or fatality, can be accessed.

The web application is based upon the latest Ordnance Survey mapping and has a detailed gazetteer to find the location you are interested in, and a number of unique selection and display features. It shows all accident locations even when zoomed out, giving a full indication of safety issues over a large area. This is particularly useful for rural locations or for looking at whole authorities.

CollisionMap is based upon our Traffweb web mapping tool, a system supplied commercially to many local and police authorities. It is totally free to use, without any need to register, and is provided by Buchanan Computing as a pro bono service to the community to promote road safety.

CollisionMap can be accessed from any modern browser at: www.CollisionMap.uk
