How did 511 get started?
The U.S. Department of Transportation petitioned the Federal Communications Commission (FCC) in 1999 for a three-digit telephone number to make it easier for consumers to access travel information services. The FCC assigned “511″ to the transportation community July 21, 2000. The term “511” has now become synonymous with traveler information. Information provided by 511 services varies widely both by provider (ranging from state Departments of Transportation to local transportation and transit agencies) and by information provided (from traffic delays and weather to transit and tourism information). To find out more about 511 services visit the 511 Deployment Coalition Website.
