Traffic Message Channel

Traffic Message Channel

Traffic Message Channel (TMC) is a technology for delivering traffic and travel information to drivers. It is typically digitally coded using the FM-RDS system on conventional FM radio broadcasts. It can also be transmitted on DAB or satellite radio. 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, traffic information can be used in the system's route calculation and the driver can have the option to take alternative routes to avoid traffic incidents.

Famous quotes containing the words channel, traffic and/or message:

    This is what the Church is said to want, not party men, but sensible, temperate, sober, well-judging persons, to guide it through the channel of no-meaning, between the Scylla and Charybdis of Aye and no.
    Cardinal John Henry Newman (1801–1890)

    Irony, forsooth! Guard yourself, Engineer, from the sort of irony that thrives up here; guard yourself altogether from taking on their mental attitude! Where irony is not a direct and classic device of oratory, not for a moment equivocal to a healthy mind, it makes for depravity, it becomes a drawback to civilization, an unclean traffic with the forces of reaction, vice and materialism.
    Thomas Mann (1875–1955)

    Children in home-school conflict situations often receive a double message from their parents: “The school is the hope for your future, listen, be good and learn” and “the school is your enemy. . . .” Children who receive the “school is the enemy” message often go after the enemy—act up, undermine the teacher, undermine the school program, or otherwise exercise their veto power.
    James P. Comer (20th century)
