Arterial Management Program
The FHWA is pleased to present the updated Model Systems Engineering Documents for Adaptive Signal Control Technology (ASCT) Systems. The update is based on feedback received from stakeholders across the country that have used the interim document to develop requirements for ASCT procurement. The document helps agencies to address the risks associated with ASCT implementation.
The document supports the Every Day Counts (EDC) goal of mainstreaming the use of ASCT where traffic conditions and agency resources support and can sustain implementation. To learn more about this EDC initiative, contact your local FHWA Division Office or email firstname.lastname@example.org. To discuss the document with peers or to leave feedback please visit the National Transportation Operations Coalition (NTOC) Forums and Traffic Signal Library.
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.
