.
It allows silent delivery of dynamic information suitable for reproduction or display in the language chosen by the user and without interrupting normal audio broadcast services.
Services, both public and commercial, are now operational in many countries worldwide.
When data is integrated directly into a navigation system, this gives the driver the option to take alternative routes to avoid traffic incidents.
How it works
Each traffic incident is binary-encoded and sent as a TMC message. Each message consists of an event code and a location code in addition to expected incident duration, affected extent and other details.
The message is coded according to the
Alert C standard. It contains a list of up to 2048 event phrases (1402 pr 01.02.2007) which can be translated by a TMC receiver into the language of the user. Some phrases describe individual situations such as a crash, while others cover combinations of events such as a crash causing long delays.
In Europe, location code tables are maintained on a national level, assigning numerical codes to locations (typically major junctions) on the road network. Those location tables are integrated in the maps provided by in-vehicle navigation system companies such as

TMC-Forum
TMC-Forum is a non-profit organization. The members are service providers, receiver manufactures, car manufactures, map vendors, broadcasters (public and private), automobile clubs, public authorities and others.
It is a forum to discuss traffic information related aspects. Furthermore it maintains the TMC-Standard (ISO 14819).
On 11 November 2007 the TMC-Forum and the
TPEGThe Transport Protocol Experts Group or TPEG, for short was founded in 1997 by the European Broadcasting Union.

Discussion
RDS-TMC is an extremely low-bandwidth system, with each RDS-TMC message comprising only 37 data bits sent at most 1-3 times per second, using a very basic data channel primarily designed for FM radio tuning and station name identification. Compressing entire traffic incident descriptions in multiple languages into a mere 16 bits for a location, 11 bits for an event code, plus 5 bits for an extent and a few more bits for the duration and system management might be regarded a miracle of ingenuity, whose need was dictated by constraints already set in the pre-existing

standard. Almost all the broadcast data bits were already taken.
Given so few bits to work with, one major design challenge of RDS-TMC was to find a way of using 16 bits (about 65000 locations) to describe an entire state or country. Such a system could not convey latitude-longitude data so easily available 25 years later with great precision using GPS. Instead RDS-TMC has to rely on the use of relatively lean location tables, pointing only to significant road junctions along defined national and regional highways. The precision of each traffic events' location when compared to modern GPS devices can seem to be low. The user's navigation system locates a driver to about 3 metres, but only knows that the crash is between Exit 3 and Exit 4, northbound on the motorway. This is because traffic events (accidents, congestion, burst water mains, faulty traffic lights, etc.) have to be superimposed onto the maps in users' GPS devices by matching the reported location into the location table.
Navigation system makers may maintain that if the nearest location table point (nearest significant junction) is located some distance from the point of the crash, then the traffic event might be shown on the device as being out of place. (In reality, it is shown as being on a section of main road between two junctions.) Even if the lack of accuracy causes an error of only a short distance this could make a significant difference as to how the program in the GPS device will interpret the event in relation to the user's planned route. For example, if there is roadwork close to a junction the position of the roadwork may be interpreted as being a short distance away. This could place the apparent roadwork on the other side of the junction. The consequence would be that the GPS device might not divert the user from the roadwork because it was assumed to not affect the route.
In fact, though, operationally, this level of detail may be exactly what is required. From the police and road authorities' viewpoints, it may be as just much as they wish to give out. The police may not want sightseers homing in on exact crash sites - additionally, emergency calls are often to somewhat vague locations, or may describe an incident (such as a multi-vehicle accident or an accident requiring multiple emergency vehicles for extrication, etc.) whose actual extent of disruption is more a segment of road than a specific point. Also, road authorities and local communities do not want drivers taking shortcuts through the minor residential streets now opened up by in-vehicle navigation systems. On motorways and other limited-access roads, knowing where the crash is located to 3 meters is no help to casual drivers when road junctions are kilometers apart. On city streets, the commercial needs of navigation system users may be to cut through minor residential roads and play areas, but this is not necessarily the optimum solution from a community perspective. The fact that actual public deployments of RDS-TMC listed later in this article have rarely used more than 10% of the available locations suggests that it may be public policy as much as technology that is currently limiting the system's precision.

. These incident reports are also being received from Google on mobile phones and handheld devices that are in vehicles already. Laws on the use of mobile devices may determine that this is potentially dangerous, but it exists and is working today. In conclusion, though, what this discussion has missed so far is that live incident reports themselves are almost always highly uncertain in terms of precise locations. But if it is assumed that these will get better, we now have technology required to provide the data. It is now up to society to regulate how much detail shall be given, and how safe it is for users to use these data in real time while they drive.
Security
In April 2007 research about RDS-TMC was presented at the CanSecWest security conference by two Italian security researchers.
The presentation, titled
Unusual Car Navigation Tricks, raised the point that RDS-TMC is a wireless cleartext protocol and showed how to build a receiver and transmitter with cheap electronics, capable of injecting false and potentially dangerous messages.
The TMC Forum responded to this claim by stating that the effects of any 'pirate' TMC broadcasts would be minimal or even non existent, due to the fact that TMC equipped receivers filter out information that does not lie on the planned route. Also, it was stated that such broadcasts would directly interfere with that country's TMC carrier station, which would contravene the respective laws of that county, leading to criminal or civil liability. It was therefore concluded that such a motive is unlikely, given the legal risks and minimal disruptions that could occur if the perpetrator were successful in broadcasting a TMC signal.

Devices and Navigation Programs
An RDS-TMC receiver is in effect a special FM radio tuner that can decode TMC data. Satellite TMC receivers utilize a dedicated data channel that is broadcast as part of the much larger broadcast digital audio channels. TMC decoding is carried out by matching event and location codes against look-up tables of phrases and locations that can be translated into audio or displayed on a Sat nav device. The look-up tables must be implemented in a service-specific database mapped to geographic routes and intersections. As with the navigation systems themselves, periodic upgrades are needed as the road system changes. These steps provide opportunities for vendors to generate revenue from users who cannot use the system unless they have the latest lookup tables.
The technical concepts of RDS-TMC started to be developed about 30 years ago, initially by
