Each year around 225000 people are reported injured in road accidents in urban areas of Great Britain. One of the most important injury causation mechanisms is the closing speed of the impact itself and the relative vulnerability of the parties involved. Specifically, in collisions between cars and pedestrians, the pedestrians' chances of being killed rise dramatically with an increase in the speed of the car. The probability of a pedestrian fatality is 5 per cent at 20 m/h, rising to 37 per cent at 30 m/h and to 83 per cent at 45 m/h. This is clearly crucial in urban areas with speed limits currently set at 30 to 40 m/h. A reduction in motor traffic speed to 20 m/h would not only reduce the levels of pedestrian injuries sustained in collisions, but also give both parties a better chance of avoiding the collision in the first place. This paper describes the background to the treatment of accidents in urban residential areas in the U.K. and northern Europe. Two case studies are presented from work recently carried out on behalf of Walsall Metropolitan Borough Council and Birmingham City Council.
