Background on 511
In July of 2000, the Federal Communications Commission assigned 511 for nationwide access to travel information services. 511 is an abbreviated dialing code for travelers to access highway, multi-modal, and other pertinent travel information via landline or wireless phones. By collecting travel information, NCDOT is able to disseminate information to the public, the users of the NCDOT highway system, to assist in the safe and efficient movement of people and goods. By giving the public access to travel information like construction, incidents, traffic, and transit, the public can make educated decisions about travel times, routes, and modes.
