This is an English translation from the talk description:
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.
could this be useful for embedding info in server generated web pages that are then picked up by a JavaScript. e.g. a tom-select country picker that gets its data from an embedded RX structure?
That post reads like fully LLM-generated. It's basically boasting a list of numbers that are supposed to sound impressive. If there's a coherent story, it's well hidden.
Open systems provide plenty of opportunity for smaller businesses to provide innovative and convenient services. What kind of innovation and experimentation other then getting more ads in are the gatekeepers that we have today interested in doing as long as there's no competition?
I've found https://dokku.com to be a great (self-hosted) alternative to heroku. For hobby and small company size a cheap root server will do great. I've been running one at Hetzner for ~5EUR/month for more than a year now and had a very smooth experience.
An option that I like to use is Middleman (or any other static site generator) for creating the pages and Netlify for hosting, all for free even with your own domain and HTTPS.
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).
As a regular train traveller here in Austria and I'm very curious how this turns out.
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.
There's also one being built in the southern part of Austria: http://burgbau.at/burgbaufrie/?page_id=428 (unfortunately not every part is translated to English but only available in German).
