#22I really wish Lyft invested in maintenance. I used Citibike this week for the first time in about a year, and the Hudson River Greenway dock by NY Waterway had 1/3 of its empty docks broken with flashing red lights, then about 5 ebikes that needed service.
Are you sure that wasn't the "staggered" bike dock? It forces you to dock in the rear row if the neighboring two front row spaces are free. This is to fit more bikes. The blinking red docks aren't broken. They're intentionally unavailable.

Also, the 5 e-bikes probably didn't need "service", they were just waiting for battery swaps. This is by design. The docks don't charge them.
CitiBike maintenance is generally fine. They're not leaving any significant number of broken bikes or docks. I think you may have just misunderstood how it works.

#23this is really nice. One request: when searching for a station name, let me type "and" instead of "&" e.g. typing "E 47th St and 2 Ave" would still return "E 47th & 2 Ave".

#24Cool project. Thanks for sharing!
The link above points to a 404 error page on GitHub. Looks like you forgot the hyphen in the name part of the url.
I’m working with subway data, particularly the A subway line, 32 mi long with about 2million trips over 6 months across 66 stations. Trying to train a convlstm to learn the spatiotemporal propagation of train headways.

That's cool it actually came from citibike
They show a bike at a location, if it's rented it will disappear off the map, if it's "returned" (available to hire again) it will show back up on the map, but at a different location.
So "represents one real bike ride" is... I guess a lawyer would say technically true.
I was recording similar location data of a Car2Go-like service for a year or two some years ago, I realize considering they charge rentals by the minute, I could estimate how much they earn by analyzing how long the cars disappear for.

#27How is MapBox going for this free tool? Is it costing you money?
It definitely will if it blows up more. I'm willing to eat it for now because I think it's art that more people should see!
Is MapLibre GL a cheaper (free?) open source alternative?
Cool stuff btw. I’m trying to visualize weather model data myself (millions of points) at https://futureradar.net and have been researching client-side techniques like yours.

#28It's often interesting to observe the different ways that privacy is approached in the US and Europe. In Europe we often accept pretty grave restrictions of our liberty like the UK's Online Safety Act, which would never fly in the US, and we do so without much public comment. On the other side of things, organisations in the US happily expose datasets like this one, which would give a most EU Data Protection Officers…
This data is mandated by NYC law: https://intro.nyc/local-laws/2015-99
I've heard that releasing these sorts of data sets help competitors do market research, and thus mitigates "winner takes all" forces. NYC also tends to be fairly pro-public-datasets: https://data.cityofnewyork.us/browse?%3BsortBy=most_accessed...

#29Relevant callout from https://bikemap.nyc/about : * Limitations * The data only contains the start and end station for each trip, but does not contain the full path. Route geometries are computed for each (start station, end station) pair using the shortest path from OSRM. This means that the computed routes are directionally correct but inexact. Trips that start and end at the same station are filtered out since the…
Hmm, definitely too bad. Essentially fictional

#30It says “entire history” but seems to start at Jan 1, 2025?
