The A9 Trunk Road is the main route that connects central Scotland and the Highlands

  • The A9 Trunk Road is the main route that connects central Scotland and the Highlands

  • It stretches from Dunblane, situated north of Stirling, and travels north bypassing Perth and Inverness before finishing in Thurso

  • The route is made up of single and dual carriageways with varying speed limits

  • It carries a broad mix of road users comprising local drivers, commuters, freight transport and tourist traffic





The A9 Safety Group was set up by Transport Scotland in July 2012

  • The A9 Safety Group was set up by Transport Scotland in July 2012

  • The multi-agency group is made up of representatives from

    • Transport Scotland
    • Police Scotland
    • Road Safety Scotland
    • The Highland Council
    • Perth and Kinross Council
    • Road Haulage Association (RHA)
    • Freight Transport Association (FTA),
    • Confederation of Passenger Transport (CPT)
    • Stagecoach
    • Safety Camera Partnerships
    • BEAR Scotland


“The main aim of the A9 Safety Group is to work together before and during the A9 dualling programme to explore any measures which could be introduced on the route using engineering, enforcement, education and encouragement to positively influence driver behaviour in a way that helps reduce road casualties”

High severity of accidents at junctions

  • High severity of accidents at junctions

    • • 53% of right turn accidents are KSI’s (Killed or seriously Injured) compared to a north east unit average of 29%
  • Higher number of accidents involving HGV’s above 7.5 tonnes

    • • 17% involve HGV’s compared to a north east unit average of 9%
  • High number of single vehicle accidents striking roadside objects



77% of all KSI accidents occurred on single carriageways

  • 77% of all KSI accidents occurred on single carriageways

  • Single carriageway KSI ratio (0.32) is above the trunk road national average (0.24)

  • Higher number of accidents involving HGV’s above 7.5 tonnes

  • HGV’s above 7.5 Tonnes are nearly 3 times more likely to be involved in an injury accident on single carriageways than they are on other Scottish trunk road single carriageways

  • HGV’s involved in 22.8% of all accidents on single carriageway sections

  • Goods vehicles under 7.5 tonnes are involved in 13.6% of accidents on single carriageway sections compared to a north west unit average of 7%



High severity of accidents at junctions

  • High severity of accidents at junctions

    • • 43% of accidents occurred at a junction compared to a north west unit average of 26%
  • Turning right manoeuvres is the most common vehicle manoeuvres in accidents

    • • 13.5% compared to a north west unit average of 6.1%
  • Failing to look properly, failing to judge other persons speed, careless/reckless and poor turning practices are the most common recorded contributory factors





Police Scotland Trunk Roads Patrol Group was formed to raise visibility with the public across the trunk road network which includes the A9

  • Police Scotland Trunk Roads Patrol Group was formed to raise visibility with the public across the trunk road network which includes the A9

  • Aim to positively influence driver behaviour and enforce legislation with a view to reducing casualties

  • Speed Enforcement by Northern, Tayside and Central Safety Camera Partnerships (SCPs)

  • SCP enforcement through 5 Fixed Safety Cameras

    • Dunblane to Perth (3)
    • Perth to Inverness (2)
  • And widespread mobile enforcement (109 sites) across the entire route

  • SCP’s reported that the level of detected offences remain a concern



Set up a brand and strapline to promote future initiatives

  • Set up a brand and strapline to promote future initiatives

  • Creation of a dedicated website to be a platform for communication

  • Set up a communications strategy to promote safety campaigns

  • Work has begun on the first A9 Safety Group campaign on overtaking

  • A9SG to carry out further research on driver frustration



Transport Research Laboratory with SIAS carried out research into the potential impacts of increasing the HGV speed limit on single carriageway sections of the A9 along with the deployment of an average speed camera system

  • Transport Research Laboratory with SIAS carried out research into the potential impacts of increasing the HGV speed limit on single carriageway sections of the A9 along with the deployment of an average speed camera system

  • .

  • The research indicated that the introduction of effective speed enforcement alone would result in a decrease in accidents.

  • It considered HGV speeds being retained at 40 mph and the increase to 50 mph

  • The A9 Safety Group subsequently agreed that after reviewing the available evidence and research that Average Speed Cameras will have a positive impact on driver behaviour and safety on the A9



The A9SG understand how important the movement of freight is to the Highlands

  • The over involvement in accidents of Heavy Goods Vehicles greater than 7.5 tonnes raises particular concerns

  • HGV’s above 7.5 Tonnes are nearly 3 times more likely to be involved in an injury accident on single carriageways of the A9 (Perth to Inverness) than they are on other Scottish trunk road single carriageways

  • HGV’s above 7.5 Tonnes are involved in nearly a quarter of all accidents on single carriageways on the A9 (Perth to Inverness) yet only make up typically 7% of the traffic

  • The research indicates Average Speed Cameras (ASCs) will improve safety, regardless of whether the HGV above 7.5 Tonnes speed limit is retained at 40mph (or increased to 50mph)

  • However, it indicates that the operation of cameras at 40mph is the safest option and the group agreed Average Speed Cameras will improve safety on the A9



Transport Minister announced that average speed cameras were to be installed following advice from the A9SG

  • The A9 system will be the second in Scotland, the first was installed on the A77 in Ayrshire between Bogend Toll and Ardwell Bay in 2005.

  • It delivered a 46 per cent reduction in fatal accidents and 35 per cent reduction in serious accidents

  • The system will operate on the A9 from just north of Keir Roundabout (Dunblane) to just south of Raigmore Interchange (Inverness). This is approximately 136 miles (220 km’s)

  • It is expected that the cost of the system will be in the region of £2.5 million. Transport Scotland as the Trunk Road Authority will pay for this initiative

  • The nature of the A9 in terms of its length, geometry, vehicle speeds and accident record (high proportion of KSI accidents which by nature are often a function of speed, and wide distribution of accidents across the route) indicate that an ASCS could positively influence road safety on this route

  • We expect the scheme to pay for itself through accident savings within the first year of its operation.



To improve safety ahead of dualling we are

  • To improve safety ahead of dualling we are

    • Before and after A9 user surveys
    • Carry out further research on driver frustration
    • Continued high visibility enforcement by Police Scotland
    • Public information events to be held in November 2013
    • First road safety campaign on overtaking
    • Further assessment of potential 50 mph HGV pilot
    • Education around National Speed Limits and Driver Behaviour
    • Implement additional road improvement schemes
    • Install average speed cameras
