Taking action on poor road safety
Pedestrian fatality risk and impact speed
The relationship between speed and injury severity is particularly critical for vulnerable road users such as pedestrians and cyclists.
For example, pedestrians have been shown to have a 95% chance of survival when struck by a car travelling at 20mph or below, a 60% chance of surviving an impact at 30mph, and a 5% chance of surviving an impact at 40mph - see chart (source: http://www.who.int/violence_injury_prevention/publications/road_traffic/world_report/speed_en.pdf).
So speed limits of greater than 20mph should be implemented only where there are very few pedestrian and cyclist movements.
