You may think this illuminated map created by BBC is stunning at first, but once you realize that this tragic image displays the location of 2,396,750 road crashes in Great Britain from 1999 to 2010, your delight will quickly fade away. Each light point is an individual collision which resulted in a casualty. The intensity of brightness shows where collisions are more frequent.
BBC has also provided several videos that animate 12 years of road crash data. Each light point is the site of a road collision resulting in injury. The brighter the lights, the more collisions have occurred. During the morning and late rush hours, the maps pulse with light.
Although the map is grim in nature, I think it's safe to assume that the information gathered here is used to help prevent more traffic accidents from occurring in the future.
