Travelers' Information Stations

In this document, the Commission amends its rules pertaining to public safety Travelers' Information Stations (TIS), which Public Safety Pool-eligible entities operate to transmit noncommercial, travel-related information over AM band frequencies to motorists on a localized basis. One current TIS rule requires the filtering of audio frequencies transmitted over TIS. Specifically, the Commission relaxes the rule to require the filtering of audio frequencies above 5 kHz instead of 3 kHz. This rule change will enable TIS operators to improve the audio quality and intelligibility of TIS broadcasts, thus improving their ability to communicate clearly with the traveling public.
