Traffic Telematics

One core competency at the bmt comes in the convergence of modern broadcast technologies and traffic information systems. A majority of communication and information technologies work together in this field. The bmt supports and operates legacy systems and services in this area, and is engaged in R&D of innovative new products in the field as well. By request it also offers consulting services.

What is traffic telematics?

Traffic telematics and digital broadcasting – synergies

Traffic telematics applications require an uninterrupted exchange of information between those involved in traffic and central information hubs. While individual targeted information/queries are transmitted from the traffic participants, the central hubs have the opportunity to disseminate information of relevance to those end participants.

Long before the reality of traffic telematics, mobile phones and GPS systems, it was the broadcasting networks which provided spoken traffic reports to keep end consumers up-to-date. Improvements in technology have made it possible for this information and additional content to be bundled as inaudible data together with the audible program (RDS-TMC).

Broadband broadcast media have been available at the very latest since the introduction of digital broadcasting systems that allow for the digital co-transmission of supplemental data. In the process, new opportunities in the traffic telematics field have arisen as well. Digital broadcasting systems enable a broadband, permanent data channel to be established to a vehicle, capable of transmitted almost any content desired; In contrast to point-to-point communication (such as GSM, TMTS,…), there are almost no connection costs for the end customer.

Traffic telemetrics services at present include traffic notifications in text form, such as for example graphic traffic overviews, flight departure schedules, parking lot availability, update data for GPS and much more. In the future, TPEG will be one of the methods used to bring an improved flow of traffic information to consumer devices.

The first TPEG services via wireless broadcasting networks (DAB+) were introduced in Germany in early 2014. As with most European broadcast projects, the bmt is a supplier for central system components.


For years the bmt has been active in the specification of analyses and implementation of TPEG (Transport Protocol Expert Group) services. This includes both consulting services and the following products from the bmt for TPEG:


The TPEG ON AIR playout system facilitates the preparation of broadcast-ready TPEG notifications for dissemination via DAB/Internet, for example.

TPEG Editor

The TPEG Editor is a tool for the creation and modification of TPEG files. It can be used to open TPEG files and present their content in a clearly laid out user interface where all fields can be edited.

TPEG Analyser

The TPEG Analyser provides a real-time graphic depiction and assessment of multiple TPEG data streams. It is also possible to record data streams and analyze existing data streams.
