Bike infrastructure and signaling in your country?

We have equivalently signs here in finland, though often you'll see bike paths marked by simple painted bikes on the ground. In recent years I've started seeing it designated by a red colored pavement. These are nice, but really curbs seem to be the only thing that reliably separates bikes and pedestrians.

We also have "pedestrian zones/roads" marked by these signs.

The sign is deceptive, as they actually mean that bikes are explicitly allowed. The signs designate squares and wide areas where cars are NOT allowed.
