Although the general public are demanding action to reduce the number of pedestrians killed in road accidents in residential areas, road bumps in these areas should be abolished. Road bumps were introduced to residential areas because they were cheap, quick to implement, and showed that Local Authorities were acting to reduce road deaths. They are admittedly effective at restricting the speed of traffic but they also hinder emergency services. The London Ambulance Service has stated that they cause delays in reaching critically ill people and this results in 500 deaths per year from heart failure alone in the London area. Electronic speed signs, and more effective signing of speed limits in residential areas, would be just as effective at reducing pedestrian deaths.
