About the research

The objective of this research is to document Automated Traffic Signal Performance Measures (ATSPM) best practices and case studies that highlight the benefits, costs, strategies and implementation scenarios that successful early adopters use to meet realistic and useful objectives and performance-based management of traffic signal programs. Support for implementation of ATSPM is increasing, but there is a need to develop and document a comprehensive methodology for evaluating costs and benefits of objectives and performance-based traffic signal operations and maintenance. This support effort will include methodology white papers, case studies from state and local agencies, and a best practices guidebook based on existing reference sources on performance-based traffic signal management.
