On the back of rooting around on the Transport Scotland website for Rail 2014, I came across the latest (June 2011) edition of Cycling by Design:
and also available in PDF:
"Cycling by Design was originally published in 1999, having been developed by Scotland’s national and local road authorities and cycling groups. The document was designed to draw together and rationalise existing international cycle design guidelines into a single comprehensive reference document which could be used as a source of sound technical advice."
