I recently learned that with smart traffic lights cyclists can change traffic lights -https://nltimes.nl/2026/04/28/new-app-turns-traffic-lights-g...

Found out about this today, up until now 802.11p hardware is very expensive, and so you cannot easily do anything with V2x messages like CAM or SPAT, but the fact this was done with sub £20 hardware is really interesting.

We need global open congestion data. At least on the european scale.

It's important so that alternatives to Google Maps and Waze (Google) can emerge.

To create congestion data, one needs to own an OS with location tracking, or be an international mobile network. Won't happen.

[disclaimer : I work on an open source alternative to big tech's maps]

I haven't seen a theme on OSM data look this modern and fresh before. Beautiful color palette and iconography!

Huge performance issues for me trying to use it on Chrome. But I like the idea.

Cool, but it there's no links for more info, and it doesn't seem to work in the USA at all.

It will be nice if we everybody could just add own receivers, then it will be quickly cover more cities. But still nice project.

I don't get this at all. Is this a live view of the traffic lights, buses, and more? How do they get the data?

I wonder if this could be used to track location of the vehicle

Am I the only one here who thinks this is intrusive?

Hug of death? Nothing loads.
