Most state agencies have a formal process in place to distribute aviation funds. Each process varies greatly from state to state. The TRB Airport Cooperative Research Program's ACRP Synthesis 123: State Aviation Funding: Project Prioritization and Selection Processes documents the various state aviation agency project prioritizations, selections, and justifications for funding aviation under state grant programs.

In the absence of comprehensive guidelines related to standards for surface apron and ramp markings, airports have worked with their specific stakeholder groups (such as airlines and ground crews) to develop unique apron and ramp marking practices that meet their operational needs. Consequently, variations are seen in apron and ramp markings at airports across the United States. The TRB Airport Cooperative Research Program's ACRP Synthesis 122: Airfield Apron and Ramp Surface Markings  documents air...

Unexpected flight diversions may impact airport operations from routine to emergency incidents. The TRB Airport Cooperative Research Program's ACRP Synthesis 121: Managing a Flight Diversion with an Emergency Response at Small, Non-Hub, or General Aviation Airports compiles practices that small, non-hub, and general aviation airports use when planning for and responding to flight diversions that involve an incident or an emergency.

The technology procurement process includes sourcing and acquiring software, hardware, and services. Systems and nuances of technology procurement vary within each airport, and navigating such variances at a pace that meets the airports’ needs and technology evolution can be challenging. The TRB Airport Cooperative Research Program's ACRP Synthesis 120: Airport Software Solutions and Services Sourcing identifies the efficient and innovative technology sourcing and procurement practices developed by airpo...

Global reports of bee declines have fueled efforts to reduce threats to pollinators and raise public awareness of bees as pollinators of our food crops and native plants. Some airports have implemented pollinator-friendly practices and programs that restore habitat for bees and bring public awareness and appreciation to these fascinating insects. The TRB Airport Cooperative Research Program's ACRP Synthesis 119: Considerations for Establishing and Maintaining Successful Pollinator Programs on Airports su...

Parking is important for airports. More than 70 percent of airline passengers and visitors at most airports use private vehicles to access the airport, and public parking is an important contributor to an airport’s finances and revenues, frequently representing the largest source of non-aeronautical revenues at most airports. The TRB Airport Cooperative Research Program's ACRP Synthesis 118: Airport Parking Pricing Strategies provides information airport staff and others require to select and to implemen...

The increasing need to use airport land for non-aeronautical revenue and decrease operating expenses may generate consideration of on-airport farming operations and agricultural leasing. The TRB Airport Cooperative Research Program's ACRP Synthesis 117: Agricultural Operations on Airport Grounds compiles literature and practices at airports to initiate and manage agricultural operations on airport grounds.

Airports make facilities available for non-commercial purposes, such as for community use by community or nonprofit groups. The TRB Airport Cooperative Research Program's ACRP Synthesis 116: Examples of Facility Space Provided for Community Use at Airports  provides the first body of literature to focus on the use of facilities that airports may provide in order to support local economic and social sustainability.

An airport emergency plan (AEP) is meant to support airports in defining roles and responsibilities of stakeholders during emergencies, identifying specific threats that could affect airports, and establishing communication protocols for the airport community. The TRB Airport Cooperative Research Program's ACRP Synthesis 115: Practices in Airport Emergency Plans gathers relevant data specific to AEP practices that can effectively be applied to other airports, including general aviation airports, whether ...

Every airport that aspires to high ratings must offer an engaging arts program because these are offered by all of the world’s most highly rated airports. It is also now generally accepted that airport arts programs yield many additional benefits for airports, passengers, and the communities in which airports are located. Airport arts programs have become an amenity that airport passengers now expect, and they serve to tether an airport to its local community. The TRB Airport Cooperative Research Program...
