Longfellow Bike Count: Year 2

It's kind of hard to believe that it's been more than a year since my first Longfellow Bridge bike count, but it has. I've posted just a few times since then about the bridge, and seen the inbound lanes deconstructed, the towers come down, and, arch-by-arch, the bridge is now being rebuilt. I even went out in the middle of winter (and by out, I mean in to someone's office with a view of the bridge) and counted about 90 bikes per hour: 30% of the previous summer's crossings. (I think I tweeted this during the winter but didn't write a whole post.)

So it was high time for a new count. I waited for a morning with good weather (and when I wouldn't miss November Project) and set off for the bridge. After chatting with the DPW workers on my street about Hubway, I didn't make it on to the bridge until 7:45, but that meant I was there in plenty of time to hit the peak morning bike rush hour, which (still) occurs from approximately 8:10 to 9:10 on the Longfellow. While at first the bike counts seemed flat or even down, once the rush got cranking, it became clear that there are more bicyclists this year than last.

Just to review, here are the bike counts for the peak hour from last year:

Wednesday, June 19, 2013: 267 bicyclists (8:12 – 9:12)
Tuesday, July 30, 2013: 308 bicyclists (8:08 – 9:08)
Tuesday, October 15, 2013: 298 bicyclists (8:11 – 9:11)

Here's what I found this June (on the 24th, a Tuesday). The counts today peaked from 8:07 to 9:15 (that is to say, the 8:07 – 9:07 hour and the 8:15 – 9:15 hour saw the same counts). And the number of cyclists during those 60 minute blocks?

384

That's one bike every nine seconds for an hour. Compared with the highest count last year in July, it's an increase of 25%. Compared with the average of the three counts last year, it's an increase of 32%. In a single year.

I can't think of any single factor that would have increase bicycle usage by that much, other than more people riding bikes. So, contrary to any mitigating factors, I'm operating under the assumption that bicycling eastbound across the Longfellow is up by at least 25% this year. Between 8:30 and 9:00, there were 221 cyclists crossing the bridge and only 187 vehicles: 18% more bikes than cars. There were a few moments where the bridge looked downright Copenhagenish. With more bicyclists than vehicles crossing the bridge at peak times, perhaps it's time to revisit the design and give bikes more than 20% of the road's real estate.
