This report gives practical examples of how some authorities have slashed the toll of death or serious injury in the last three years by as much as three-quarters. From our consultations with authorities this year on the roads featured, we reveal the simple, relatively inexpensive engineering measures that are paying dividends – improvements to signs and markings, particularly at bends, and the layout and signalisation of junctions. These actions are affordable, particularly when done as part of a well planned maintenance regime. If we are to save lives for less it is essential we are more systematic and more targeted on what we know works.
