3D Zebra Crossings

The first 3D zebra crossing has been installed in the UK on St. Johns Wood High Street (borough of Westminster) – see http://tinyurl.com/y5h33jnr . They have been used in other countries such as Iceland and are designed to look like the road contains vertical boxes. They won’t fool anyone after the first drive over them, but might cause unfamiliar drivers to slow down, or brake abruptly which might be positively dangerous.

These are using the same principle as painted speed humps (they look like real road humps until you drive over them). They are of course much quieter than conventional humps. They have been used in a few streets in the UK, including some in London. But the lack of widespread adoption rather suggests that they are less effective in slowing traffic.
