Check out the article "DC Cycling, Bike Lane Usage Decline Dramatically"
at
https://saveconnecticutave.org/f/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.

Your objection is noted. But I don't think it counters the fact that bike facilities do not normally generate huge increases in bike mode share, as promised. Locally, I've seen zero evidence of increase - although there are admittedly few bike lanes here. But for years I've observed and occasionally used bike lanes in two nearby cities I frequently visit. I almost never see other cyclists using them. And one major city a bit more distant has lots of bike lanes, but IME they always appear to be empty.
Sometimes there are surges in bike mode share. Portland was famous for that; but while it lasted for years, the bicycling fashion seems to have passed. See https://bikeportland.org/2023/03/15/city-counts-reveal-data-behind-portlands-precipitous-drop-in-cycling-371407
Pittsburgh currently has lots of visible cyclists, especially in its University area. But data now unavailable on the web once made clear that the surge in bike use happened before, not after, the surge in bike facility construction. We'll see how long that surge lasts.
As I've mentioned many times, the U.S. probably has added thousands of miles of bike facilities in the past 15 years. But bike mode share is still stuck way down below one percent.
We've "built it" in city after city. Despite the _Field of Dreams_ fantasies, they haven't come.
