Airports are vital national resources. They serve a key role in transportation of people and goods and in regional, national, and international commerce. They are where the nation’s aviation system connects with other modes of transportation and where federal responsibility for managing and regulating air traffic operations intersects with the role of state and local governments that own and operate most airports. Research is necessary to solve common operating problems, to adapt appropriate new technologies from other industries, and to introduce innovations into the airport industry. The Airport Cooperative Research Program (ACRP) serves as one of the principal means by which the airport industry can develop innovative near-term solutions to meet demands placed on it.
The need for ACRP was identified in TRB Special Report 272: Airport Research Needs: Cooperative Solutions in 2003, based on a study sponsored by the Federal Aviation Administration (FAA). ACRP carries out applied research on problems that are shared by airport operating agencies and not being adequately addressed by existing federal research programs. ACRP is modeled after the successful National Cooperative Highway Research Program (NCHRP) and Transit Cooperative Research Program (TCRP). ACRP undertakes research and other technical activities in various airport subject areas, including design, construction, legal, maintenance, operations, safety, policy, planning, human resources, and administration. ACRP provides a forum where airport operators can cooperatively address common operational problems.
ACRP was authorized in December 2003 as part of the Vision 100—Century of Aviation Reauthorization Act. The primary participants in the ACRP are (1) an independent governing board, the ACRP Oversight Committee (AOC), appointed by the Secretary of the U.S. Department of Transportation with representation from airport operating agencies, other stakeholders, and relevant industry organizations such as the Airports Council International-North America (ACI-NA), the American Association of Airport Executives (AAAE), the National Association of State Aviation Officials (NASAO), Airlines for America (A4A), and the Airport Consultants Council (ACC) as vital links to the airport community; (2) TRB as program manager and secretariat for the governing board; and (3) the FAA as program sponsor. In October 2005, the FAA executed a contract with the National Academy of Sciences formally initiating the program.
ACRP benefits from the cooperation and participation of airport professionals, air carriers, shippers, state and local government officials, equipment and service suppliers, other airport users, and research organizations. Each of these participants has different interests and responsibilities, and each is an integral part of this cooperative research effort.
Research problem statements for ACRP are solicited periodically but may be submitted to TRB by anyone at any time. It is the responsibility of the AOC to formulate the research program by identifying the highest priority projects and defining funding levels and expected products.
Once selected, each ACRP project is assigned to an expert panel appointed by TRB. Panels include experienced practitioners and research specialists; heavy emphasis is placed on including airport professionals, the intended users of the research products. The panels prepare project statements (requests for proposals), 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, ACRP project panels serve voluntarily without compensation.
Primary emphasis is placed on disseminating ACRP results to the intended users of the research: airport operating agencies, service providers, and academic institutions. ACRP produces a series of research reports for use by airport operators, local agencies, the FAA, and other interested parties; industry associations may arrange for workshops, training aids, field visits, webinars, and other activities to ensure that results are implemented by airport industry practitioners.

ACRP Research Report 274: Accommodating Peer-to-Peer Carsharing at Airports: A Guide provides airport practitioners with suggested practices for accommodating peer-to-peer (P2P) carsharing companies, which allow individuals to make their personal vehicles available for rent by others through a company-provided app. Airports are increasingly becoming locations of P2P activity, and practitioners who are considering how best to accommodate P2P operations will find this report of particular interest.
P2P carsharing companies allow customers to reserve, pick up, and return a motor vehicle (most commonly owned by an individual) through a company-provided app for a fee. While P2P carsharing continues to grow across the United States, information on the nature of this activity at airports and how it affects revenue, operations, safety, and facilities is limited. Research was needed to better understand the P2P carsharing market and to develop a playbook to help practitioners accommodate this emerging activity at their airports.
The research team, led by InterVISTAS Consulting, began with a literature review of P2P carsharing and related services. The team then conducted a web-enabled survey of the 100 largest U.S. airports to identify those that had entered into or were negotiating agreements with P2P carsharing companies. Of those airports, the survey asked them to provide key information about fees, vehicle transfer locations, volume of activity, and other relevant data. Several airports, of various sizes, geographies, and agreement types, agreed to also serve as case studies, providing more detailed information.
The guide begins with an introduction to P2P carsharing and a quick start guide. These are followed by more detailed information on P2P’s quickly evolving trends, including general profiles of P2P carsharing customers and vehicle owners, the regulatory landscape, recent litigation, and general airport practice relative to P2P activity. The guide then offers recommended practices and suggested business terms to help airport practitioners accommodate P2P activity at their facilities reflecting the impacts to terminal curbside roadways and other facilities, considerations for stakeholders, security, vehicle handoff locations, and P2P facility needs. The guide also provides detailed considerations and suggestions for developing P2P agreements. In addition to the guide, published as ACRP Research Report 274, the following deliverables are available on the National Academies Press website (nap.nationalacademies.org) by searching for ACRP Research Report 274: Accommodating Peer-to-Peer Carsharing at Airports: A Guide:
