The A9 Safety Group's report into the route between Dunblane and Inverness contains collision and casualty data for the first 18 months of operation of the average speed cameras (to 30 April 2016) which is the mid-point of their evaluation period. (The other performance data covers the period to 30 June 2016 unless otherwise stated.)"The overall summary is that there continues to be a sustained improvement in driver behaviour and a corresponding fall in collisions and casualties," the report says. "In human terms four fewer people have been killed, 22 fewer seriously injured and 62 fewer people slightly injured on the A9 in this 18 month period compared to the equivalent baseline period. There are also additional benefits brought through reduced incidents and their subsequent impact, which has improved journey time reliability."The main headlines from the data monitoring are:
- ? The number of fatal casualties between Dunblane and Inverness is down by over 33% compared to the baseline average
