Ramping it up

[abstibus]

Are there any regulations governing the height of speed ramps and the distance they must be apart? The private company that manages my work car parks has just installed two new ramps at each exit (no notice or warning given) and they seen terribly high and close together. No-one speeds there anyway, as we have to use the ticket machines. I would welcome any advice.
Thanks

If they are on private property then it's up to the owner. If they are on the public highway, there are strict rules.

Aristotle,
It's an educational establishment - is that private or public?
Thanks

If it's not the public highway, I think it counts as private even though the owner may be an education authority.
