Prang finder site reveals accident blackspots
Road crash map from gobbled UK gov data
Launched on 27 September, CrashMap is the first application to make use of the Road Accidents and Safety dataset that was released on 30 June this year.
Older maps exist, though this seems to be the most comprehensive to date and it contains over a million incidents. The map lists incidents as slight, serious or fatal and has data from between 2005 and 2010. Data for 2011 will be added when the department releases it.
Users can rove around the map or search for areas by postcode.
It's not pin-point accurate: "Incidents are plotted to within 10 metres of their location and as such, can sometimes appear to be off the carriageway," explains their site.
One other limitation is that that you need to be zoomed in close to see the pins.
