The number of miles of UK roads monitored by average-speed cameras has been revealed in a new study.
Research has found that 51 sections of road in the UK are managed by the cameras, adding up to 263 miles in all.
Assessing a driver’s speed between two different points in the road, average-speed cameras have been utilised across wide stretches of the UK road network.
They were first introduced in 2000, in Nottingham. In 2013, the number of miles they covered was 127.
The amount of cameras used has grown significantly in recent years, with 12 new systems installed in the last year. They range from a mile-long stretch on Tower Bridge in London, to a 99-mile section on the A9 between Dunblaine and Inverness.
Richard Owen, from Road Safety Analysis, the company behind the research, said: “Some of the old fixed-speed cameras have been around for 25 years and they are based on 35mm film.
“They are coming to the end of their life so as they are replaced, they’re sometimes getting replaced with average-speed camera systems.”
The boom in the use of average-speed cameras comes after a falling cost of installation. In the early 2000s when the cameras first graced our roads, the cost per mile was around £1.5 million. However now, that cost has fallen to around £100,000 per mile.
The House of Commons’ Transport Committee has recently recommended the increased use of the cameras, stating that they “are generally better received by motorists than traditional fixed-speed cameras.”
