A view from above of a bike lane in the city centre. Whenever the bike lane - in the city centre - crosses an intersection or a car lane, this lovely blue colour makes everyone involved aware that bikes are present.Cars wishing to turn into the turn lane in the photo above must wait for any bikes to pass before doing so.The little bike symbol at the bottom of the photo is for bikes turning right. The wide blue lane is for bikes who are heading straight. The intersection is maybe 20 metres to the right out of shot.
Busses, too, get great priority, as you can see from the clearly marked bus lane at the top.
