A road in our region has been named the most improved in the country.

Speed cameras and traffic management have transformed a 13-mile single carriageway section of the A605 in Cambridgeshire from just outside Peterborough, through Whittlesey and out to the busy junction with the A141.

Figures show fatal and serious crashes fell from 34 to just nine. Speed enforcement with fixed and mobile cameras is in use on all but two of the 10 most improved roads.

Fatal and serious crashes on the 10 most improved routes have dipped from 541 in the period 2001-2005 to 209 in 2006-2010, the study showed.

This represents a saving of #35 million a year, the figures from the Road Safety Foundation, sponsored by insurance company Ageas, found.

A section of the A120 from Puckeridge in Hertfordshire to Braintree in Essex is also named in the top ten most improved roads.

Changes to the layout and traffic management at junctions are common features, and other measures include new traffic signals to control traffic flow; restricting turning movements on to roads with high traffic levels or poor visibility; widening entry and exit lanes with changes to lining and signing; advanced warning signs; and installing high friction and coloured surfacing.

The survey also revealed not just the roads with the worst safety record but, for the first time, also listed the busy higher-risk roads. A section of A1101 from Outwell in Norfolk to Long Sutton in Lincolnshire is named in this list.

These busy higher-risk roads have higher-than-average traffic flows, a high crash density and an above-average risk rating.

Britain's persistently highest-risk road is a stretch of the A537 from Macclesfield in Cheshire to Buxton in Derbyshire.
