TRANSIT COOPERATIVE RESEARCH PROGRAM The nationâs growth and the need to meet mobility, environmental, and energy objectives place demands on public transit systems. Cur- rent systems, some of which are old and in need of upgrading, must expand service area, increase service frequency, and improve efficiency to serve these demands. Research is necessary to solve operating prob- lems, adapt appropriate new technologies from other industries, and introduce innovations into the transit industry. The Transit Coopera- tive Research Program (TCRP) serves as one of the principal means by which the transit industry can develop innovative near-term solutions to meet demands placed on it. The need for TCRP was originally identified in TRB Special Report 213âResearch for Public Transit: New Directions, published in 1987 and based on a study sponsored by the Urban Mass Transportation Administrationânow the Federal Transit Administration (FTA). A report by the American Public Transportation Association (APTA), Transportation 2000, also recognized the need for local, problem- solving research. TCRP, modeled after the successful National Coop- erative Highway Research Program (NCHRP), undertakes research and other technical activities in response to the needs of transit ser- vice providers. The scope of TCRP includes various transit research fields including planning, service configuration, equipment, facilities, operations, human resources, maintenance, policy, and administrative practices. TCRP was established under FTA sponsorship in July 1992. Proposed by the U.S. Department of Transportation, TCRP was authorized as part of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA). On May 13, 1992, a memorandum agreement outlining TCRP operating procedures was executed by the three cooperating organi- zations: FTA; the National Academies of Sciences, Engineering, and Medicine, acting through the Transportation Research Board (TRB); and the Transit Development Corporation, Inc. (TDC), a nonprofit educational and research organization established by APTA. TDC is responsible for forming the independent governing board, designated as the TCRP Oversight and Project Selection (TOPS) Committee. Research problem statements for TCRP are solicited periodically but may be submitted to TRB by anyone at any time. It is the responsibility of the TOPS Committee to formulate the research program by identi- fying the highest priority projects. As part of the evaluation, the TOPS Committee defines funding levels and expected products. Once selected, each project is assigned to an expert panel appointed by TRB. The panels prepare project statements (requests for propos- als), select contractors, and provide technical guidance and counsel throughout the life of the project. The process for developing research problem statements and selecting research agencies has been used by TRB in managing cooperative research programs since 1962. As in other TRB activities, TCRP project panels serve voluntarily without compensation. Because research cannot have the desired effect if products fail to reach the intended audience, special emphasis is placed on disseminat- ing TCRP results to the intended users of the research: transit agen- cies, service providers, and suppliers. TRB provides a series of research reports, syntheses of transit practice, and other supporting material developed by TCRP research. APTA will arrange for workshops, train- ing aids, field visits, and other activities to ensure that results are imple- mented by urban and rural transit industry practitioners. TCRP provides a forum where transit agencies can cooperatively address common operational problems. TCRP results support and complement other ongoing transit research and training programs.

The National Academy of Sciences was established in 1863 by an Act of Congress, signed by President Lincoln, as a private, non- governmental institution to advise the nation on issues related to science and technology. Members are elected by their peers for outstanding contributions to research. Dr. Ralph J. Cicerone is president. The National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the nation. Members are elected by their peers for extraordinary contributions to engineering. Dr. C. D. Mote, Jr., is president. The National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the nation on medical and health issues. Members are elected by their peers for distinguished contributions to medicine and health. Dr. Victor J. Dzau is president. The three Academies work together as the National Academies of Sciences, Engineering, and Medicine to provide independent, objective analysis and advice to the nation and conduct other activities to solve complex problems and inform public policy decisions. The Academies also encourage education and research, recognize outstanding contributions to knowledge, and increase public understanding in matters of science, engineering, and medicine. Learn more about the National Academies of Sciences, Engineering, and Medicine at www.national-academies.org. The Transportation Research Board is one of seven major programs of the National Academies of Sciences, Engineering, and Medicine. The mission of the Transportation Research Board is to increase the benefits that transportation contributes to society by providing leadership in transportation innovation and progress through research and information exchange, conducted within a setting that is objective, interdisciplinary, and multimodal. The Boardâs varied committees, task forces, and panels annually engage about 7,000 engineers, scientists, and other transportation researchers and practitioners from the public and private sectors and academia, all of whom contribute their expertise in the public interest. The program is supported by state transportation departments, federal agencies including the component administrations of the U.S. Department of Transportation, and other organizations and individuals interested in the development of transportation.

TCRP Report 183: A Guidebook on Transit-Supportive Roadway Strategies (1) identifies consistent and uniform strategies to improve transportation network efficiency to reduce delay and improve reliability for transit operations on roadways; (2) develops decision- making guidance for operational planning and functional design of transit/traffic opera- tions on roads that provides information on warrants, costs, and impacts of strategies; (3) identifies the components of model institutional structures and intergovernmental agree- ments for successful implementation; and (4) identifies potential changes to the Manual on Uniform Traffic Control Devices (MUTCD) and related documents to facilitate implementa- tion of selected strategies. TCRP Report 183 is a resource for transit and roadway agency staff seeking to improve bus speed and reliability on surface streets while addressing the needs of other roadway users, including motorists, bicyclists, and pedestrians. TCRP Project A-39, âImproving Transportation Network Efficiency Through Implemen- tation of Transit-Supportive Roadway Strategies,â conducted an extensive review of transit- preferential treatments used in the United States and internationally, including information on when these treatments are applied and how they are designed. The researchers interviewed a number of transit and roadway agencies to identify lessons observed and effective practices from actual project implementations, with a particular focus on successful techniques for transit agencies, roadway agencies, and project stakeholders to work together toward out- comes that benefit all parties involved. The project presents findings from a series of gap- filling research efforts on (1) innovative international strategies not yet in common use in the United States; (2) a simulation study of the effects of stop location, transit signal priority, and queue jumps on bus and general traffic travel times and travel time variability; (3) an evalu- ation of selected strategies implemented in the Seattle area; and (4) identifying conditions when the delay benefit produced by a strategy at an upstream intersection is lost at the next downstream signal, resulting in no net benefit. Finally, the research report identifies possible changes to the next edition of AASHTOâs Guide for Geometric Design of Transit Facilities on Highways and Streets, based on the findings of this project. This project created three products that are available on the TRB website (www.TRB.org) by searching for âTCRP Report 183â: (1) this guidebook, (2) a research report on the method- ology used to develop the guidebook (TCRP Web-Only Document 66), and (3) a PowerPoint presentation describing the entire project.
