On saturday, I cycled up Chalmers St and turned right on to Lauriston Place. I noticed that while there was red chip in the surface to denote a cycle lane, there was no white line. I queried the neighbourhood team and got this reply:

Perhaps we should start referring to them as "informal guide lanes"

Eh? Why bother then? I didn't realise that 4.75m is too narrow for (being ambitious) 1.75m of cycle lane and a lane for a car (average car eg Ford Focus is 2m wide).
"Informal Guide" - is this not what all advisory cycle lanes are?
That road is more than wide enough for sure. Obviously not helped when there are buses parked on it...

So the road is too narrow to provide space for cyclists to be safely past by motorists and their solution is to add some coloured chips to discourage cyclists from taking primary.
Face, meet palm.

I wonder how wide Gogar Station Road is, using the same measurement process?
And are Edinburgh cyclists going to have to carry long tape measures now as well as brushes to clear broken glass?
I know that in certain states of USAnia, some cyclists have had to measure the widths of carriageway lanes in order to prove that they are allowed to 'take the lane' per statutes that 'require' cyclists to otherwise cycle as far to the right as possible (for certain carriageway widths).

GSR is 6-7m wide where there is lanes but this reduces to <6m at each end hence the evaporating lanes

So a road would have to be 9.5 metres from kerb to kerb to justify white lines on the cycle lanes?
Since the red chips are all but invisible to car drivers anyway, the white line is about the only thing that indicates the presence of a

This doesn't sound right to me. There are plenty of examples of advisory cycle lanes on roads narrower than that.
Transport Scotland's Cycling by Design says the optimal width of a with-flow bus lane is 4.6m and a 1.5m wide advisory cycle lane may be provided within it. It also mentions roads where cycle lanes have been included but centrelines have been omitted if there isn't enough for two full general traffic lanes (one in each direction).Posted 8 years ago #
