Where C-ITS is actually live. This page is purely geographic — which regions have deployed C-ITS, and what people have really received there. Which vehicles and infrastructure transmit in the first place is covered on Senders.

Two different kinds of information end up here, and they are worth keeping apart:

• Deployment — a documented rollout by an operator, a city or a road authority. Backed by a source: a project page, a press release, a tender.
• Sighting — somebody actually received something and can say so. Backed by the live map or by a capture.

A deployment does not guarantee that anything is on the air today, and a sighting can exist without any published project behind it. Both are useful, so both are listed, but they are marked differently.

Adding an entry: register a wiki account and add it yourself. For a sighting, the useful details are the date, the location, the message type and — if you have it — something identifying, such as a tram line, a course number or the intersection. A screenshot from the live map helps. For a deployment, add the source link.

TODO: Additional markers were discussed but not yet decided — for example whether messages are signed, and whether a location has infrastructure (RSU) or only vehicles (OBU). Please settle the set of markers before the list grows further, so that entries do not have to be reworked later.

☑◉ Traffic lights, trams and buses. Trams and traffic lights are regularly visible on the live map; the traffic lights send MAPEM and SPATEM.

☑◉ 12 RSUs installed, plus OBUs in 74 scheduled buses and 3 automated shuttles.

☑◉ ASFINAG has equipped the Austrian motorway network with C-ITS on a large scale. RSUs along the network, plus roadworks safety trailers sending DENMs.

☑◉ ACCorD test field. The parts that carry C-ITS infrastructure:

• Vaalser Straße in Aachen, part of the B 1 — 8 signalised intersections
• Campus Melaten of RWTH Aachen — several RSUs along the 2.4 km urban test section
• L 232 near Herzogenrath and L 240 near Alsdorf — 3 signalised intersections each, on rural roads outside the city

☑◉ 13 RSUs at traffic lights documented, eight in Ulm and five along Reuttier Straße in Neu-Ulm, from three different manufacturers. Trams and buses transmit as well, several of them with a wrong or unassigned line number.

Vehicle sightings are not tied to a place — a Golf 8 transmits wherever it drives. They are therefore listed by model on Senders rather than here.

In short: what you receive as a vehicle is almost always a Volkswagen Group model, occasionally a Cupra Born, plus special-purpose and commercial vehicles belonging to the projects above.
