 There is evidence that well-targeted road safety improvements save lives, at both individual locations and across networks.For example, on a section of the A4128 in the UK, speed reductions, improved signs and markings, intelligent road studs, traffic calming and upgraded pedestrian crossings helped cut the number of fatal and serious crashes from 19 in 2004–06 to two in 2007–09 – an 89% reduction.The Safer Roads Investment Plans include extensive planning and engineering information such as road attribute records, countermeasure proposals and economic assessments for 100 metre sections of road.
