=v= Unfortunately this infographic has come under fire from the
Oregon DOT, who argued that the user fees/general funds balance
(the dollar sign graphic) wasn't as bad as indicated, so the
BTA changed it. What's more, there was quibbling over "road
costs" vs. "transportation costs" to confuse the issue even
further. Two media sources have spun this as suggesting that
maybe bikes need to pay more after all. SMDH
=v= Even worse, in my eyes, is that the road damage numbers
(the 1 car and 9,600 bikes in a set of scales graphic) is an
underestimate! The Sierra Club has a different estimate, and
here's how they calculated it:
170lb person on 30lb bike = 200lb
Car or SUV weight = 4000lb
(The average car is 3000lb but SUVs bring the average up.)
Ratio car/bicycle = 20
20 to 4th power = 160,000
So really we're talking 1 car to 160,000 bikes. But impact is
also a function of velocity, so multiply that by how much faster
cars go than bikes for a given location.
=v= The BTA infographic on this item was footnoted with a few
studies, including one arguing that the 4th power is too low,
but their number isn't even as high as a 4th power calculation.
Very confusing.
