Â© 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 techniquesâ 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.

AUTHORÂ ACKNOWLEDGMENTSÂ FirstÂ andÂ foremost,Â manyÂ thanksÂ mustÂ beÂ givenÂ toÂ theÂ projectÂ panelÂ forÂ theirÂ dedicationÂ toÂ producingÂ guidanceÂ aboutÂ performanceâbasedÂ managementÂ ofÂ trafficÂ signals.Â TheÂ panelÂ membersÂ wereÂ consistentlyÂ engagedÂ andÂ providedÂ timelyÂ feedbackÂ overÂ theÂ courseÂ ofÂ thisÂ project.Â DataÂ isÂ onlyÂ usefulÂ whenÂ itÂ becomesÂ information,Â andÂ theÂ panelÂ contributedÂ greatlyÂ toÂ theÂ developmentÂ ofÂ aÂ guidebookÂ thatÂ presentsÂ comprehensiveÂ butÂ focusedÂ information.Â TheyÂ encouragedÂ theÂ projectÂ teamÂ toÂ pushÂ theÂ envelopeÂ whenÂ itÂ cameÂ toÂ theÂ presentationÂ ofÂ thatÂ information,Â resultingÂ inÂ aÂ guidebookÂ thatÂ isÂ highlyÂ visual,Â searchable,Â andÂ sharable.Â ManyÂ ofÂ theÂ panelÂ membersÂ workÂ forÂ publicÂ agencies,Â butÂ theÂ projectÂ teamÂ alsoÂ engagedÂ additionalÂ publicÂ agencyÂ staffÂ atÂ theÂ onsetÂ ofÂ theÂ project.Â ItÂ wasÂ importantÂ toÂ evaluateÂ aÂ crossâsectionÂ ofÂ publicÂ agencyÂ needsÂ relatedÂ toÂ theÂ managementÂ ofÂ trafficÂ signalÂ systemsÂ inÂ orderÂ toÂ developÂ contentÂ thatÂ wouldÂ beÂ usefulÂ toÂ aÂ diverseÂ arrayÂ ofÂ agencies.Â TheÂ followingÂ publicÂ agencyÂ contributorsÂ respondedÂ toÂ writtenÂ surveysÂ andÂ participatedÂ inÂ interviewsÂ withÂ theÂ projectÂ teamÂ toÂ disseminateÂ theirÂ knowledgeÂ andÂ perspectives.Â BecauseÂ ofÂ theÂ panelÂ andÂ publicÂ agencyÂ contributors,Â thisÂ guidebookÂ isÂ vastlyÂ moreÂ comprehensive,Â forwardâthinking,Â andÂ applicableÂ toÂ aÂ wideÂ varietyÂ ofÂ agencies.Â PUBLICÂ AGENCYÂ PARTICIPANTSÂ JoannaÂ Bush,Â WisconsinÂ DepartmentÂ ofÂ TransportationÂ AlanÂ Davis,Â GeorgiaÂ DepartmentÂ ofÂ TransportationÂ RobÂ Klug,Â ClarkÂ County,Â WashingtonÂ JimÂ Larsen,Â AdaÂ CountyÂ HighwayÂ District,Â IdahoÂ LingÂ Li,Â VirginiaÂ DepartmentÂ ofÂ TransportationÂ SteveÂ Misgen,Â MinnesotaÂ DepartmentÂ ofÂ TransportationÂ ShitalÂ Patel,Â RegionalÂ TransportationÂ CommissionÂ ofÂ SouthernÂ NevadaÂ RajÂ Ponnaluri,Â FloridaÂ DepartmentÂ ofÂ TransportationÂ MarthaÂ Styer,Â CaltransÂ NhanÂ Vu,Â VirginiaÂ DepartmentÂ ofÂ TransportationÂ CharlieÂ Wetzel,Â SeminoleÂ County,Â FloridaÂ
