[Tagging] Enforcement of access rules

I wish to map the cameras that my municipality is installing these days to
enforce the access restriction in the ZTL ( = limited traffic area). I
think the most appropriate structure to do this would be the enforcement
relation [1], but none of the listed types of enforcement is up to the

I would therefore suggest adding a new type of enforcement:
enforcement=access, possibly further detailed by an access=* tag (and all
possible specifications, like foot=yes/no). The relation would have to
include as members both the device node (more on this later), and the way
it guards the access to (which may also mean that no explicit access
details need to be included in the relation, because they should already be
specified on the guarded way).

About the device: I haven't found a suitable tag for such a camera. Should
we think of a specific tag (like, highway=access_camera), or rather should
we try to come up with a more generic way of indicating an electronic
detector? Perhaps, something like enforcement_device=*, with possible
values like speed_camera, access_camera...

Do you have critiques or suggestions?
