CrashMap uses data collected by the police about road traffic crashes occurring on British roads where someone is injured which is then compiled in to an easy to use format showing each incident on a map. This data is approved by the National Statistics Authority and reported on by the Department for Transport each year. Northern Ireland data is not provided proactively and has been obtained through an FoI request. Incidents are plotted to within 10 metres of their location and as such, can sometimes appear to be off the carriageway when zoomed in very closely.
The CrashMap team cannot accept responsibility for errors within the data and all queries relating to accuracy should be directed to the appropriate authority. If you would like to understand more about how the data is collated and reported please visit the Department for Transport Website.
The data includes all incidents up to the end of the previous year and will be updated as soon as the latest data is released by the Department for Transport (usual in June or July). If provisional data is available then this will be included with a caveat that it may be subject to deletion, addition or change.
To make each report as accessible as possible to users of the site, the report is broken up into 2 clear sections.
Part 1 deals with the information that you are most likely to want to understand about the incident such as when it happened, at what time of day, how serious was the incident, how many vehicles were involved, how many casualties were there, what type of road was it on or what was the weather like.
Part 2 then provides much more detailed information if you need it about each vehicle and casualty to allow you to get an understanding of the types of vehicle, the gender and age bands of any casualties, the gender and age bands of any drivers, what manoeuvre the vehicle was performing at the time of the incident.
Where the collision description text has been provided by a local authority or police force then this is also included. Authorities who want to contribute to the dataset or embed map feeds from CrashMap can get in touch with the development team.
