Raised junctions

[Lardy Ninja]

This is slightly off topic but does anyone know why when side roads meet a main road, the junctions
are sometimes raised to the same level as the pavement? This is supposed to be a safety feature but
I have no idea what makes it safer than a normal junction where the road stays below the the
pavement level. Any ideas or links to research?

The intention is apparently both the psychological effect of a gate, and the speed limiting effect
of what I am old enough to know as a sleeping policeman. The technical term for this traffic
calming is an "entry treatment", and what you have is a raised entry treatment. See "vertical
deflections" at:

Yes it is "safety" for when the car driver swerves to avoid that stealth cyclist he will not damage
his cars suspension on the council owned Kerb!

It's known as a plateau junction. The idea is that perceived priority and convenience is returned to
pedestrians. ie No bumping up and down at each junction. Safety benefit derives from the
driver/cyclist/road user feeling he/she is moving into ped territory rather than peds feeling
intimidated by having to move into car territory.
