The A9 Safety Group strategy was developed around the analysis of the accidents on the route which produced the following statistics:
Dunblane to Perth
High severity of accidents at junctions
53% of right turn accidents are KSIs (Killed or Seriously Injured) compared to a North East unit average of 29%.
Higher number of accidents involving HGVs above 7.5 tonnes
17% involve HGVs compared to a North East unit average of 9%.
High number of single vehicle accidents striking roadside objects
The annual average daily traffic flow between Dunblane and Perth is approximately 25,000 vehicles per day. Cars make up 81.8% with all goods vehicles making up 17.4%.
Perth to North of Inverness (Tore Roundabout)
Higher number of accidents involving HGVs above 7.5 tonnes
HGVs 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 any other Scottish trunk road single carriageways.
HGVs involved in 22.8% of 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%
