What's the point in this road furniture?

^ That's a weird one. Encouraging people getting the bus to cross right in front of it.

Sounds about right for a council traffic scheme. I've nearly hit several people walking out from behind the front of a bus.
I'd love to know (but not enough to actually lookup) what research was done into the effectiveness of humps and chicanes in different contexts, and how often the schemes are re-evaluated after they have been implemented. Most of them seem to only anger motorists, endanger cyclists and confuse pedestrians, and even in my most cynical moments I can't believe that is what was intended.
