Although initially envisioned as providing general information to motorists and travelers, TIS stations have also been developed for supporting emergency public safety communication, and the FCC currently licenses the stations through its Public Safety and Homeland Security Bureau (PSHSB). During a crisis mobile phone networks are often overloaded, and TIS stations can be used to broadcast emergency instructions. Also, during a widespread electrical outage stations equipped with reserve battery or generator power can continue operating, for reception by battery-operated radios. In 2008 the American Association of Information Radio Operators (AAIRO) was formed to represent station operators, and at the time of its formation the group emphasized the ability of TIS stations to broadcast live local updates to affected communities during emergencies.
