I've been pointed to these TfL publications by Tom Bogdanowicz, leader of the infamous LCC. It makes a very interesting reading and sums up pretty much everything people riding bikes could want and what they dislike. The thing is that these guidelines are either ignored or are going to be used in the future projects, because I can hardly see them being used now. What is good however is that TfL acknowledges a couple of important points:
1) people use bicycle facilities if they are well designer, direct and with unbroken priority
2) people do not use bicycle facilities of poor design, which are a waste of investment
PS. I will be posting some interesting excerpts in the following days.
