ATSPM on Demand Webinars
Arterial roadways are a crucial link in the national transportation system providing for 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. Traffic signals provide for the safe transfer of right of way and manage the distribution of green time for vehicles, pedestrians and bicycles for signalized intersections on arterial, collector and local roads. There are more than 330,000 traffic signals in the United States serving urban, suburban and rural communities throughout the United States. Over 3,000 state, regional and local organizations are responsible for varying levels of management, operation and maintenance of the nation’s traffic signal infrastructure; valued at over $72 billion.
The goal of the Arterial Management Program is to advance the use of objectives and performance based approaches to traffic signal management, to improve design, operations and maintenance practices, resulting in increased safety, mobility and efficiency for all users.
