Installation and maintenance cost of A9 safety cameras: EIR release

I am writing to request information regarding the introduction of the Average Speed Cameras on the A9. I would like details of the exact cost of installation and maintenance,how much revenue has been made from Speeding fines since installation and what are the Statutory regulations for Average Speed camera signage. Can you also confirm if this was fully debated in parliament? What were the votes for and against? And where I can get further information regarding implementation of these cameras?
