Check out the article "DC Cycling, Bike Lane Usage Decline Dramatically"

The bicycle traffic graph of "L Street, NW" plots "Peak Hour Bike
Count".  As I read it, that's the number of bicycles that pass, in one
hour, when bicycle traffic is at it's peak for the day, week, month or
year, at one intersection.  Since there's no link to the source of the
data[1] and assuming my interpretation is correct, that seems like a
rather strange way to measure bicycle lane use.

The graph might also be a case of coincidence versus causation.  In
2017, there was a large unexplained drop in bicycle lane use, for no
obvious reason.  For all I know, it could have been caused by a
construction project, that diverted traffic to the adjacent "M
Street".  Similarly, the drop in 2020 thru 2023 might be related to
the Covid pandemic and it's change from commuting to working from
home. 

Hint:  If your conclusions are based on statistical data, kindly
provide the original source.

Searching the site for "Peak Hour Bike Count" found nothing.
