A90 Average Speed Cameras Transform Driver Behaviour

Driven by safety

Connecting the Central Belt and the North East of Scotland, the A90 is a crucial part of the strategic trunk road network. Around 23,000 vehicles use the A90 every day, carrying a mix of commuter, freight and agricultural traffic and serving the cities, towns, and villages along its route.

Improved driver behaviour

Average speed cameras (ASC) on the A90 between Dundee and Stonehaven have encouraged a significant improvement in driver behaviour.

  • 99 out of every 100 vehicles are now driving at speeds of 70mph or less. This is a significant improvement when considered against the fact 3 out of every 5 vehicles were speeding under the previous enforcement regime of fixed and mobile cameras.
  • Only 1 out of every 5000 vehicles are now driving at speeds of more than 10mph over the speed limit. This is a significant improvement when considered against the fact 1 out of every 5 vehicles were speeding excessively under the previous enforcement regime of fixed and mobile cameras.

Average speed cameras

Average speed cameras became operational on the A90 between Dundee and Stonehaven on 31 October 2017, replacing the existing fixed and mobile enforcement strategy.

We know the significant outcomes that average speed cameras can deliver from our experience on the A9 and A77, and can expect the system between Dundee and Stonehaven to realise a range of improvements, including:

  • Fewer people being killed or seriously injured. Average speed cameras are about road safety, and these systems have been a proven success on the A77 and A9;
  • Reduced incident frequency and impact, and improved journey time reliability; and
  • Improved driver behaviour and reduced offender numbers. Average speed cameras are proven to significantly reduce offender numbers.

Myth buster and FAQs

It’s all a big money making scheme

We don’t want your money: Our evidence is showing that average speed cameras on the A90 are encouraging better speed limit compliance. This leads to fewer camera detections and ultimately fewer fines for road users.

What does this mean for the A90

The 50 mile section of the A90 between Dundee and Stonehaven is a dual carriageway subject to the national speed limit with the exception of approximately a half mile section around the A937 junction with the A90 south of Laurencekirk, where the speed limit is 50mph.

Road safety framework

The Road Safety Framework 2020 aims for:

‘A steady reduction in the numbers of those killed and those seriously injured, with the ultimate vision of a future where no-one is killed on Scotland’s roads, and the injury rate is much reduced’
