The start and end of the zone can be found in TomTom SPC. The OSC database contains the exact locations of speed cameras, with a potential deviation of about 10 meters. These files cover all of Europe plus Turkey. *.ov2 files work wherever this format is supported.

Also, in case you haven't read this:

Dear users and colleagues!.

Please kindly do not publish file speedcam.txt Mod AF
(in any of its editions and versions)
on the forums
4pda.to and msieurlolo.fr .
Let's admit that posting content on these sites
is a bad idea.
The administration of these resources took a tough stance
and blocked the author (user),
Andrey Form,
therefore, any Mod AF publications
there are inappropriate and meaningless.
I hope for your understanding and respect for network ethics.
