Did you know that if your car supports *Car2X* via *ITS-G5*, it transmits its exact GPS position, speed, longitudinal and lateral acceleration, pedal positions, length and width, and much more—all unencrypted—up to four times per second on a 5-GHz band?

Trams in Graz also transmit this data, including their line numbers. This allows us to track the trams in real time and display them on a map.

Many traffic lights in Graz now support *C-ITS* and transmit data every second regarding the exact configuration of the lanes, the current signal status, and when the next phase is expected.

With an *ESP32-C5*, we can already receive this data from a distance of several hundred meters.

We’ll show you how we collect and process this data. On a live map, you can see (within the coverage area) trams, the color of the traffic lights and when they’ll change next, and which cars equipped with Car2X are currently driving and at what speed.

Using Grafana, we display historical data on traffic light cycles and statistics, such as wait times at crosswalks and in traffic lanes. We also give you access to the collected data for your own analysis.

To improve coverage, we need your help! We’ve built a board with *ESP32-C5* and *PoE* that lets you capture *C-ITS* packets yourself and share them with us for our open map, or process them on your own.

Took me quite some time to figure it out. Short explanation in the post would be great.

Die whole city (or village) is a lot into medieval stuff, so it's a really great surrounding.

You have nice static HTML pages with a CDN, super fast, and there's even a CMS option with NetlifyCMS, which works by creating git commits for you and then automatically pushes the new static version on Netlify. The basics in Netlify are free and there are nice add-ons where some are also free (e.g. forms).

Currently the Intercity/RailJet trains are more like a downgrade to what was available before. They look nicer, but provide quite uncomfortable seating and offer no possibility to change the seating inclination; due to the air condition it's very noisy; there's no place to put your feet in an elevated position; there's no compartments, the whole car is one big room; and the only option for children is an open place with a TV, you have a lot of fun chasing your small children through the train.
