Lies, damned lies, and Average Daily Bicycles Counts

Roger:

So we know that 1998 Summer traffic was 221% higher on the Morrison Bridge, and 306% higher on the Broadway Brige when compared to January 1999. But you haven't attempted any winter counts in the last 7 years?

The current headline estimates of "Average Daily Bicycle Counts" (on four bike friendly bridges) are based exclusively on data gathered in late Summer and early Fall?

Does that seem like a representative sampling...to exlude that period when traffic declines to 1/3 or 1/2 of peak summer traffic?

If anything, car usage is likely to have a negative correlation with bike usage in the winter (or at night). Why? Because people don't mind driving on a dark, wet, night in the middle of January; many of them do mind biking in that weather.

Give me a $92,000 grant, and I will gladly take a 24 hour x 4 bridge census four times/year. And I promise not to pull an Emilie Boyles on you. No data, no payment.
