© 2020 National Academy of Sciences. All rights reserved. NATIONAL COOPERATIVE HIGHWAY RESEARCH PROGRAM Systematic, well-designed, and implementable research is the most effective way to solve many problems facing state departments of transportation (DOTs) administrators and engineers. Often, highway problems are of local or regional interest and can best be studied by state DOTs individually or in cooperation with their state universities and others. However, the accelerating growth of highway transportation results in increasingly complex problems of wide interest to highway authorities. These problems are best studied through a coordinated program of cooperative research. Recognizing this need, the leadership of the American Association of State Highway and Transportation Officials (AASHTO) in 1962 initiated an objective national highway research program using modern scientific techniques— the National Cooperative Highway Research Program (NCHRP). NCHRP is supported on a continuing basis by funds from participating member states of AASHTO and receives the full cooperation and support of the Federal Highway Administration (FHWA), United States Department of Transportation, under Agreement No. 693JJ31950003.

AUTHOR ACKNOWLEDGMENTS  First and foremost, many thanks must be given to the project panel for their dedication to producing  guidance  about  performance‐based  management  of  traffic  signals.  The  panel  members  were  consistently engaged and provided timely feedback over the course of this project. Data is only useful  when it becomes information, and the panel contributed greatly to the development of a guidebook that  presents  comprehensive  but  focused  information.  They  encouraged  the  project  team  to  push  the  envelope when it came to the presentation of that information, resulting in a guidebook that is highly  visual, searchable, and sharable.  Many of  the panel members work  for public agencies, but  the project  team also engaged additional  public agency staff at the onset of the project.  It was  important to evaluate a cross‐section of public  agency needs related to the management of traffic signal systems in order to develop content that would  be useful to a diverse array of agencies. The following public agency contributors responded to written  surveys  and  participated  in  interviews with  the  project  team  to  disseminate  their  knowledge  and  perspectives.  Because  of  the  panel  and  public  agency  contributors,  this  guidebook  is  vastly more  comprehensive, forward‐thinking, and applicable to a wide variety of agencies.  PUBLIC AGENCY PARTICIPANTS  Joanna Bush, Wisconsin Department of Transportation  Alan Davis, Georgia Department of Transportation  Rob Klug, Clark County, Washington  Jim Larsen, Ada County Highway District, Idaho  Ling Li, Virginia Department of Transportation  Steve Misgen, Minnesota Department of Transportation  Shital Patel, Regional Transportation Commission of Southern Nevada  Raj Ponnaluri, Florida Department of Transportation  Martha Styer, Caltrans  Nhan Vu, Virginia Department of Transportation  Charlie Wetzel, Seminole County, Florida

Management of traffic signal systems is a critical function for every transportation agency. Thanks to advancements in technology, it is now possible to collect large amounts of data at signalized intersections, leading to the development of dozens of performance measures.

The TRB National Cooperative Highway Research Program's pre-publication draft ofNCHRP Research Report 954: Performance-Based Management of Traffic Signals provides information to help agencies invest in signal performance measures as part of a comprehensive approach to performance-based management.

Supplementary materials to the report include a data dictionary and a PowerPoint presentation.
