Arterial Management Program

Arterial roadways are a crucial link in the national transportation system that provide regional mobility and access to land use that is vital to our economy and quality of life. Arterials account for more than one million lane miles of roadway, connecting local and collector roads to the national highway systems. Over 3000 State and local agencies are responsible for the management and operation of the estimated 311,000 traffic signals that are spread across urban, suburban and rural communities throughout the United States. The objective of the Arterial Management Program is to advance management practices and operations strategies that promote the safe and efficient use of arterial roadway capacity to reduce congestion.
