You'd ride on the left-hand side, you mean? Since the sidewalk will be to the right of the bike lane. It's hard for me to know how exactly 5' will feel in this context. In a regular bike lanes, 5' is pretty tight -- but that's when you've got faster cars on one side, and an unforgiving curb on the other.mattaudio wrote:Yes, I agree: I think bike lane widths are slightly less important than their side friction. 5 feet is fine, if there's a buffer on one side. You can ride closer to the (right hand) side without feeling at risk for collision with objects or path/sidewalk users. So, what exactly is the point of a 1' buffer anyways? Why not just run the bike lane and the sidewalk up against each other, but with different materials?
But we also don't know what behavior or use will look like. Certainly, there will at some point be a need for one bicyclist to pass another. 5' isn't enough space to do that. The likely behavior will be to rely on the buffer or sidewalk.
In any case, I guess ADA requirements mandate some sort of buffer that would be discernible to blind users. Exposed aggregate is good for that (as are pavers) since they feel noticeably different to a cane.
