Excerpt from an article by Mia Birk, a well known transportation planner, at: http://www.miabirk.com/blog/?p=531
"People often ask me: what type of bikeway facility should we start with? Off-street paths? Cycle tracks, aka protected/separated bike lanes? Traditional bike lanes? Bike boulevards, aka neighborhood greenways? Shared lane markings? Together, these form a toolkit of solutions that work in concert to create a comprehensive bikeway system."
"But what is the best order? Start with an expensive yet iconic off-street path? Or fight for bike lanes on major roads because they’re more visible than bike boulevards? Or start with bike boulevards because they are less controversial and inexpensive? The truth: there is no one “right” order, as long as you’re aggressively, progressively making changes in the right direction."
