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.
