In the United States of America, XM Satellite Radio started transmitting TMC messages all over the US, as has Sirius Satellite Radio. Navteq provides traffic data to both XM and Sirius Satellite Radio. Navteq Traffic delivers traffic information and related advertising via RDS and HD signals to navigation devices nationwide. Navteq also provides high quality traffic sourced from sensors, probes and other technologies in 10+ countries as of Dec 2009. INRIX, Inc. fuses TMC data with real-time flow information from its crowd-sourced network of floating cars and mobile devices with information from other public and private sources to deliver real-time and predictive traffic information.
Clear Channel Communications and Tele Atlas have a TMC service called Total Traffic Network (TTN), using FM RDS in 77 US cities and three Canadian metropolitan areas. These services are both subscription, and were initially available to many in-car navigation units via an expansion module purchased separately.
The TomTom RDS-TMC Traffic Receiver acquires information through an FM radio signal broadcast by Clear Channel's regional providers. By connecting a compatible TomTom navigation device to the RDS-TMC Traffic Receiver, users automatically receive traffic information via the TMC connection. Once a trip is planned, traffic alerts are displayed in the traffic bar on the right hand side of the screen. When users tap the traffic bar, they receive further information, such as accident or traffic delays. The RDS-TMC Traffic Receiver is compatible with the TomTom VIA series, GO 920, TomTom GO 720, TomTom ONE XL and TomTom ONE 3rd edition. It provides integration of RDS-TMC Traffic information with the user interface of the TomTom GO and ONE products.
By now, in addition these after-market services, about six major motor manufacturers are offering RDS-TMC as standard in their U.S. vehicles, including Volvo and BMW.
Ibiquity HD Radio is advertising a TMC service based on the existing RDS-TMC standard. Utilizing the established standard for RDS/TMC, the Traffic Message Channel (TMC) is a data application for broadcasting real-time traffic information. Data messages will be received and decoded by a TMC-based receiver in conjunction with HD Radio devices and navigation systems. Traffic services are delivered to the driver in a vehicle in a variety of ways: the most common of these being a TMC-enabled navigation system.
