Bike lanes in MA, dangerous bike lanes and a possible news story
Just got the latest issue of "American Bicyclist," published by the
League of [same], and it contains a photo of a line of helmeted cyclists carefully riding single file...in the door zone adjacent to a line of parked cars. Nice. --Karen D. life member, not ready to resign so I stay out of bike lanes |

What is a gutter pan? The concrete area on the side of some roads that allows rainwater to run to a drain. The asphalt ends where the cutter pan starts. We have these in our area. When installed, the connection is flat and smooth. After a decade or so, weathering causes a gap between the two, parallel to the direction of travel. It's the sort of thing that can trap a wheel, if not completely, at least enough to require a quick correction to get out of it. -- My real name backwards: nemuaZ lliB |

JFTR I've never seen a bike lane like that around my area. (I think there might be a few cases that used to be and have been fixed quite nicely, however.) FYI (I thought I pointed this out but it isn't in the quoted text), the lane I mentioned was removed shortly after the bike lane stripe was painted, and re-installed after the problem was fixed (either by cutting back the gutter pan or by restriping the other lanes so the bike lane could be put in in accordance with state standards. We have a few very old bike lanes that are a bit two narrow, being some of the first installed in California, so they went in before the design standards existed. These are being fixed over time. -- My real name backwards: nemuaZ lliB |

With the logo we're supposed to persevere and be grateful for the indulgence of the Powers That Be deigning to give us Our Own Lane with our own tax dollars?? This is fundamentally a silly statment - the picture shows a bike lane stripe to the left of a gutter pan. From the picture, I can't tell the width of the asphault in the bike lane - to meet standards, it should be 3 feet in width or more. The logo is a standard symbol that is required every so often. It is not to impress bicyclists - drivers are supposed to stay out of bike lanes unless turning across them (in which case they must be within 200 feet of their turn before merging into the lane, yielding to any bicycles already in the lane). Similarly there are rules governing bicyclists. So the logo is there so that you don't have guess what kind of lane it is by being able to tell a 3 inch shoulder stripe from a 5 inch bike lane stripe (both solid white stripes) reliably. There is no requirement that the logo has to be totally on the asphault. -- My real name backwards: nemuaZ lliB |

Aside from the paranoia (attributing malice to what might merely be ineptness), that depends on the width of the asphault inside the bike lane. If it is three feet wide, the lane meets the design standards and and riding inside the bike lane while staying on the asphault should be easy for almost anyone. If it is substandard, the city that installed it is taking a liability risk if there is an accident (e.g., if someone catches a wheel in the slot that forms after the surface degrades at the joint between the asphault and the gutter pan). -- My real name backwards: nemuaZ lliB |
