Centralised discussion space for TfL plans and cycling in London

I haven't read the document but as it goes, advisory lane is a dashed line at the side, cars 'should' not cross the line unless necessary. Zero legal weight and widely seen as more dangerous than nothing. Mandatory lane, solid line at the side of the road, cars 'must' not enter the lane. Little legal weight and not seen as much better than the advisory lane. Segregated lane, a portion of the road with a physical demarcation, from studs to wands to kerbs to half height kerbs to orcas to armadillos... Widely favoured by the public, disliked by other campaigners.
