A9 average speed cameras
Discussion
As of this moment, there are only two cameras in each single carriageway section, and the speed is measured between each two, and doesn't carry forward. (This applies to A9 North of Perth only). There are no cameras on the DC sections.
I have conducted numerous 'real world' tests of this, and have no points....
(Sometimes there are normal mobile cameras on DC sections, but not average speed)

You are correct about the pairing however there are definitely more than 2 cameras on some of the dual sections. Take north of the dual of Crubenbeg (north of Dalwhinnie) as an example - there isn't another dual section until Slochd! That's 45 miles of numerous pairs. In that situation it's pairs of cameras 1+2, 3+4 and so on. I've heard the threshold is +10mph so you'd be making very good progress to be averaging a genuine 70+mph.

Fair enough - I should have said that I normally turn off at Aviemore. Didn't want to lead anyone astray!Almost certain...there are only 2 cameras on each single carriageway stretch between Perth and Aviemore.

The section I'm talking about is between Perth and Aviemore. The first dual section heading south from Aviemore is 20 miles away. Almost certain...there are only 2 cameras on each single carriageway stretch between Perth and Aviemore.
This from the A9 Info website.....
.....The system is visible along the A9 from just north of Keir Roundabout (Dunblane) to just south of Raigmore Interchange (Inverness). While this is approximately 136 miles (220 kms) the system will not operate over the entire length.
North of Perth there are seven distinct average speed camera system zones all of which are single carriageway sections. The cameras are generally five to seven km apart. South of Perth, there are 12 camera locations on the northbound carriageway and 11 on the southbound carriageway spaced every 5 to 7 km apart. South of Perth the cameras will address the high severity turning accidents being experienced at the cross-over junctions where the high speed through traffic is in conflict the slower turning traffic.
The longest single enforceable section on the A9 will be approximately 31 miles long, which is shorter than the overall length of the average speed cameras on the A77. The Perth to Dunblane dual carriageway section is 30 miles long, and so is also shorter than total length of the A77 system........
Here is a map showing the location of all the cameras between Inverness and Perth although I didn't think there were as many as this...

There is a set of cameras at each of those locations. http://www.invernessreds.co.uk/wp-content/uploads/...
As I said earlier in the thread though, there is one (very) small section of dual carriageway covered by the cameras.
There is a small section of single lane dual carriageway at the north Pitlochry junction.
There may be debate whether it is a 'proper' dual or just a long 'island'. But the signs for HGV limits ending (at the start) and starting again at the end would make me think it is a dual. But I suppose due to it being just a few hundred meters long then if you did do 70 on it (or more) it would make little difference to your average speed through the whole section, although it is a relatively short section.
Outrageous piece of spin by the A9 Safety Group. The A9 Safety Group only have official stats for October 2014 to June 2015 and those show that the number of fatal collisions between Perth and Inverness is 5, approximately 33% (1.25 accidents) higher than the average figure for the equivalent period over the 3 preceding years. The number of fatalities resulting from these accidents was 6, approximately 9% higher than the baseline average of 5.5.
As that is rather inconvenient the A9 Safety Group has gone instead with a press release that focuses on the absence of any deaths over the 3 month period July to September, despite their own report stating that "reporting accident and casualty figures over a period as short as a few months is not typical, with a three year period being considered more appropriate to comment on overall performance".

Drove up the A9 this weekend, first time i've done it in years and stupidly didn't realise the single carriage was 60pmh and not 70mph (yes i'm aware i'm an idiot, no need to tell me this) anyway reckon I never exceeded 74mph (sat-nav) and even then that was short lived considering it was so busy. Does anyone know if I should expect multiple points or even losing my license if i've passed so many cameras exceeding the average speed?
I done the same thing on the return journey. I'd actually just happily accept 6 points right now as it was my fault but worried i'll end up being banned.

I always wondered if you speed through all the cameras do you get a ticket for each or a single charge...say if you did 80mph along the whole section....you have only exceeded the speed limit once even though it was for a longer duration.
Its kinda like if you went shop lifting and stole a Top gear magazine in one WH Smiths and walked into another branch of WH Smiths with it still under your coat and walked back out...would you be charged with stealing it twice?

As I understand it, it would (hopefully) need to stand up in court as 2 offences. So 80 through 2x 60mph zones probably doesn't. Not sure about 80mph through a 60 and 70...Its kinda like if you went shop lifting and stole a Top gear magazine in one WH Smiths and walked into another branch of WH Smiths with it still under your coat and walked back out...would you be charged with stealing it twice?
