Huge news. @wmata API now updates every 5 seconds! Adjust your apps, people!

I made a super simple website where you can see everywhere you can get to in under an hour on the NYC subway.

The generated map is both a heat-map (changes color) and a cartogram (warps space).

I'm scraping Amtrak, and made a website to see how busy each train is!

[The FRA @USDOTFRA]

🚆Train data alert!
FRA published its quarterly report on intercity passenger train performance, covering October-December 2025. This report provides data on Amtrak passenger train operations, including the first full quarter of data from the new Mardi Gras service.

Every day, millions of people travel through New York’s subway system, spanning over 400 stations and 600 miles of track!🗽🚇 This animation illustrates how travel patterns change throughout the day.

When I moved to new york, I found it hard to visualize what commute times actually looked like.

The same dilemma occurs every time you move, or even book a hotel: what's actually accessible in 20 minutes of public transit?

Continuing our @Kpler analysis of GNSS spoofing in the Strait, this animation uses raw unfiltered AIS data to compare Feb 27 vs 28.
The chaotic tracks on the 28th show intense GNSS spoofing with red lines showing AIS “jumps” caused by interference.

[Mapbox @Mapbox]

Building ride playback with speed visualization in Mapbox GL JS?

A developer on Reddit asked how to color-code speed along a bike route (green → yellow → red) and add interactive scrubbing to reveal speed + time data at any point.

We built a working demo.

This post shows how to:
✅ Use line gradients to visualize speed variations
✅ Dynamically build gradient stops based on speed data
✅ Implement hover-based route “scrubbing” UX

Includes a live CodePen you can fork and adapt.

Built an app for cyclists who record their rides. Telemetry Studio syncs your bike computer data to video and adds overlays - power zones, heart rate, speed, GPS map, elevation.

Works with FIT and GPX files. Strava segments too.

[Martin Austermuhle @maustermuhle]

Interesting: @DDOTDC has placed two speed-sensing cameras along the Metropolitan Bike Trail that show a smiley face if you’re riding under 15 mph or a frown if you’re above. City officials say it’s to encourage safer riding, but they are also collecting speed data from cyclists.
