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

- moooo99 7mo agoThe project was shared as part of a talk at Graz Linux Tage. You can find it here, unfortunately it is only available in German https://media.ccc.de/v/glt26-688-c-its-mit-einem-esp32-ampeln-straenbahnen-und-autos-tracken https://media.ccc.de/v/glt26-688-c-its-mit-einem-esp32-ampel...
- RobotToaster 7mo agoIs there a link to the hardware they mention in the description?
- Maxious 7mo agoThey built their own circuit board but the core module that does the 802.11p is just a ESP32-C5
- RobotToaster 7mo agoYes, I understand that. The translation makes it sound like they have published the software and design, or are somehow making boards available. >To improve coverage, we need your support! We have built a board with *ESP32-C5* and *PoE* that allows you to capture *C-ITS* packages yourself, and provide us for our face-up card, or process it yourself. Edit: found it, https://codeberg.org/opentrafficmap https://codeberg.org/opentrafficmap

- localhostinger 7mo agoHappy to see this popping up here, I watched the Linux Tage talk last week. The demo just kept getting better and better, to a point where the audience just interruptively cheers and claps away. I know nothing about the contents, but this warmed my heart. True hacker project!
- walrus01 7mo agoIf I had a dollar for every time I've seen an American on the Internet assume that anything published in the English language must be US-centric...
- rootusrootus 7mo agoConversely, if I had a penny for every time someone complained about Americans... ;-)
- dawnerd 7mo agoThat's one way to get rid of our (US) pennies now that they're useless!
- bravoetch 7mo agoYou still wouldn't have nearly as many dollars if you subtracted the times those people were correct in that assumption. Personally I assumed the site would be global. It doesn't have any info though, so I rely on finding out somewhere else I guess.
- lucideer 7mo ago> Personally I assumed the site would be global The only reason you would assume a site would be global is if your definition of "global" is "works in the US" & you never bother to check for support of other countries. I live in the anglosphere outside of the US & I encounter more than enough US-only web projects for that not be to a default assumption I hold. Most sites are not global - it's very odd to assume they would be.
- BigToach 7mo agoAnother reason could be that calling this OpenTrafficMap gives an impression that it is similar to OpenStreetMap, which is global.

- felixguendling 7mo agoIt's based on Car2X/Vehicle2X data that's sent unencrypted and can be received with chips you can order from China.
- rootusrootus 7mo agoWill be interesting to see how it fares when it does come to the US. It seems like there are some cars that already have the tech installed. But the US is allegedly more interested in the cellular version, which I am guessing is not as easy to pick up with a simple receiver? My gut feeling is that this seems like one of those things likely to face a lot of backlash when it becomes widely known.
- felixguendling 7mo agoI guess we only find out if some people order those chips and check if there is some data. From my understanding the idea is the same like maps showing air planes or ships (for ships it’s AIS). So without volunteers/pioneers who participate we won’t know. It seems like traffic lights and trams also can send data.
- uyzstvqs 7mo agoThe site is definitely lacking. It's half in German, half in English. The concept is that there is this protocol called ITS-G5, which is a European profile of 802.11p. Vehicles and traffic infrastructure can transmit telemetry on 5 GHz. Other vehicles and traffic infrastructure can use it for situational awareness. This website collects that data using local receivers and aggregates it onto a map, similar to what website like ADSB-Exchange do with ADS-B. What is concerning is that vehicles appear to broadcast a MAC address. Does this mean that ITS-G5, 802.11p, and C-ITS could be used for persistent tracking?
- alexpotato 7mo agoThis should be a top level comment as it has a ton of useful info and can be voted to the top.
- softgrow 7mo agoReading the translation of the talk, public transport vehicles have a persistent MAC but for private cars the MAC address changes every 15 minutes.
