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. [1] "Source: DDOT" is not a good source: Searching the site for "Peak Hour Bike Count" found nothing. -- Jeff Liebermann jeffl@cruzio.com PO Box 272 http://www.LearnByDestroying.com Ben Lomond CA 95005-0272 Skype: JeffLiebermann AE6KS 831-336-2558
