Governmental entities, as well as park districts and authorities,
may be eligible to operate a Travelers' Information Station (TIS, also called Highway Advisory Radio)
for the purpose of disseminating information by broadcast radio to travelers. A license is required
before construction of, or operation of, a Travelers' Information
Station. This service, which was created in 1977 by
the Report and Order in Docket 20509, FCC 77-414, 67 FCC 2d 917 (1977), is
covered under rule 47 CFR 90.242. Travelers' Information Stations operate in the AM Broadcast
Band (530 kHz - 1700 kHz) and are limited to a 10 watt transmitter output power, an antenna height no greater than
15 meters (49.2 feet), and a coverage radius of 3 km. These stations may not transmit
commercial information. This service is not available to
individuals or groups, but only to governmental entities
and park districts. See47 CFR 90.242 and 47 CFR 90.20(a).
State and Local Governments may also create state-wide networks to provide
non-commercial public safety information via radio using LPFM stations (see the LPFM page).
Applications for this type of service must be filed on Form 318 during
LPFM filing windows, and will be processed by the Audio Division, Media Bureau.
