I'm all for bike lanes as long as they do not take away space from the sidewalk, and especially as long as they do not widen roads. Otherwise, it's just a stealth attack on walkers by drivers, who will happily take advantage of the extra space.
What I've noticed is that a lot of people are afraid of using the bike lanes still. I've been bumped by bikers and I asked them why they weren't using the bike lane next to them, and they said it felt too dangerous. Still I did see other people using them, so, hopefully the long term effect will be to make people more comfortable. Maybe they should put a wider line and reduce the vehicle lane width on that particular road.
Mass ave still scares the hell out of me even after they put in the bike lanes - people get killed around MIT at least once every year or two - if they'd only change the laws to make motorists culpable for hitting pedestrians and cyclists it might change things around here.
In response to Itchy:
I've been biking around Boston for over 10 years (and have been using bikes as a mode of transit since my training wheels came off)- I'm definitely not one of those weird bike fanatics who ride fixed gear and hang out at the otherside, not a very good environmentalist (I threw a plastic bottle in the trash today, and I had a hamburger for lunch), I am pretty photogenic, though
- I have some basic bike tools I don't really know how to use very well, and I don't own fancy biking clothes or gear - just a helmet and lights.
I want better bike infrastructure (yes, it's REAL infrastructure) because I don't like the hassle of having to find (and pay for) parking near my office, I don't like sitting in traffic - and I really don't like taking the T during rush hour. I live too far to walk, but it's only about a 30-40 minutes by bike. However, there are still a couple spots that are very dangerous unless I go a considerable amount out of my way. I used to walk to my old job (like 14% of Bostonians - and almost a quarter of Cantabrigians) in all sorts of weather in professional clothes and somehow managed. IMO - if you work up a sweat riding you're pushing yourself or more likely out of shape - if you go at a reasonable pace it's just like walking at a brisk pace.
also - I'm pretty sure a very large number of the population that works in the city proper lives within 5-10 miles of their workplace - easy biking distance. And if people could take bikes on the trains during rush hour...
I think before copenhagen started expanding their bike infrastructure they only had about 10% of the population commuting by bike (still far more than the 2% we have in Boston - which has actually doubled in the past few years) - but now it's well over 50% in the city, and over 40% in the suburbs. Boston is compact and relatively flat enough, the weather isn't actually that bad (Minneapolis has a much stronger bike culture, and I hear it's just lovely there in the winter), and I know there are plenty of people like myself who would prefer to bike places, but won't because we're afraid of getting run over - and we're not militant enough or are a little put off by the hard-core biking organizations around here. I think if the city builds bike lanes and does a good job marketing them, people will definitely use them.
