Counting Traffic pt 2

So here's my overdue post from my Harvard Bridge count. Tuesday afternoon, the same day as my Museum of Science Bridge Traffic count, I sat for another two hours, on another bridge, and counted traffic

My view to the left. What a beautiful day to waste!

I sat on the inbound side of the Harvard bridge, close to the Cambridge river bank, at approximately 360 smoots. Surprisingly, traffic was not at all bad (in both directions). Thus, Not only was I able to divide my counts into fairly precise bins of 7.5min, I also managed to record each wave of cars separately and differentiate between cars coming from Mass. Ave. and Memorial Dr.

I'm dead tired so I don't think I'll be saying much. But briefly...

So it's interesting thing how the ratio for different modes of transportation changed. There were a lot more cyclists crossing the Harvard Bridge, and slightly fewer pedestrians. Harvard Bridge is a much longer bridge and it seemed unlikely that many of these people were commuting to and from work. Also, I should note that I was recording the inbound side of the bridge during the evening commute. If it included any commuters, they would be reverse commuters. Also, the plot isn't up yet, but vehicular traffic doesn't actually increase that much (maybe ~20%). Just from my observation, the outbound side of the bridge also didn't seem to increase much in volume.

Anyway, a lengthier review of the data should be coming soon, but not before Parking Day! We've moved location to Inman square now and the weather looks like it will be great! I'm quite excited! Please look forward to the next entry!
