Following a detailed review which included analysis of accidents, vehicle speeds, traffic flows and existing speed enforcement statistics, the A9 Safety Group developed a strategy of changes to improve driver behaviour along the route. This was broken down into three sections:
- Dunblane to Perth
- Perth to North of Inverness (Tore Roundabout)
- North of Inverness to Thurso
With 36% of all car drivers exceeding the speed limit on the A9, the strategy had a strong focus on enforcement measures including both average speed cameras and mobile camera enforcement. Both elements of the enforcement strategy had a proven track record of reducing casualties as well as speed.
The Average Speed Camera System deployed on the A9 is the SPECS3 incorporating the Portable Outstation Device.
