CHART provides real-time information concerning
travel conditions on the main roads in the
primary coverage area. Traveler information
on planned or accidental traffic disruptions, such as
accidents, chemical spills, snow, ice, floods, major special events, seasonal
recreational peaks, and roadway construction. CHART uses several ways to
disseminate traveler information, including:
- Variable Message Signs (VMS), which are programmable message
boards (permanent and portable) capable of displaying real-time traffic
information to motorists.
- Highway Advisory Radio (HAR) stations which are low power radio
stations that provide information on traffic conditions and special
- Commercial radio and television broadcasts - by providing accurate and
timely information to commercial broadcasters, CHART reaches a wide
audience of listeners and viewers.
- Travelers Advisory Telephone (TAT) is currently used for summer beach
traffic [Reach-the-Beach (800) 541-9595], and is in the planning phase for
possible broader application.
