511 Traveler Information

Access to 511 traveler information systems remains limited. Telephone services for travelers provide real-time information about work zones, traffic incidents, and other causes of congestion. They allow travelers to make more informed decisions about their travel routes or modes and increase safety by helping motorists avoid areas with congestion or incidents. The U.S. Department of Transportation (USDOT) petitioned the Federal Communications Commission in 1999 for a three-digit dialing code for travel information and was assigned 511 in 2000. In 2001, the Cincinnati, OH, area became the first location in the country to use 511 for travel information. Why is 511 needed? Before the 511 dialing code was assigned for travel information, more than 300 different telephone numbers provided travel information in the United States. A test drive in 1999 showed that 11 different numbers were required to access travel information on a trip from Washington, DC, to New York, NY. As 10-digit phone numbers and new area codes proliferate, a single, easy-to-remember number will help local and interstate travelers and shippers avoid delays and save time.
