Public-use airports, metropolitan planning organizations (MPOs), and local land-use/ transportation planning agencies all have independent yet interrelated planning processes bound by legal and policy requirements to ensure compatibility. This means that they should work cooperatively to solve joint transportation challenges in the most effective and efficient manner. The TRB Airport Cooperative Research Program's ACRP Research Report 216: Guidebook for Assessing Collaborative Planning Efforts Among Airp...

Many airports undertake stormwater projects to accommodate facility expansion, address obsolescence, and respond to evolving regulatory requirements. Often, stormwater infrastructure is installed or upgraded on a project-by-project and piecemeal basis, resulting in mismatches of sizes, material types, ages, and conditions. When airports are considering expanding or improving their stormwater facilities, the immediate need for stormwater infrastructure modification may not be clear, and a benefit–cost ana...

Incompatible land uses can threaten the safe utility of airports and expose people living and working nearby to potentially unacceptable levels of noise or safety risk. At the state level, all 50 states have enacted some form of airport zoning legislation since the 1950s. The majority of states (90 percent) have enacted laws mandating or enabling local governments to adopt, administer, and enforce airport zoning regulations. The TRB Airport Cooperative Research Program's ACRP Research Report 206: Guidebo...

Proposals are due August 11, 2020 at 5:00 PM Eastern.

Sixty-eight percent of the states who responded to a survey indicated their agency has a documented process for as-built development. They said handwritten notes were the most commonly used method to capture as-built data (86%), followed by electronic notes (76%), and then photographs (33%). Some states use more than one option to capture as-built data. The TRB National Cooperative Highway Research Program's NCHRP Synthesis 548: Development and Use of As-Built Plans by State Departments of Transportation...

TRB's Airport Cooperative Research Program (ACRP) Research Report 155: Guidebook for Advanced Computerized Maintenance Management System Integration at Airports explores the use of a Computerized Maintenance Management System (CMMS) to manage a variety of assets across a number of different airport systems. This report develops guidance on the steps necessary to implement a CMMS, factors for consideration in prioritizing which systems should be included in the CMMS using a phased approach, and the steps ...

“Pavement condition data” are essential inputs to the process of managing airport pavements and ensuring safe operations. The technology available today to collect pavement condition data is considerably different from that available even 20 years ago, and new technologies are being developed and introduced into practice at a rapid pace. ACRP Research Report 203: Guidelines for Collecting, Applying, and Maintaining Pavement Condition Data at Airports provides guidance on the collection, use, maintenance,...

Airports worldwide are setting aggressive zero- or low-emissions targets. To meet these targets, airports are deploying new strategies, adopting innovative financing mechanisms, and harnessing the collective influence of voluntary emissions and reporting programs. In tandem, new and affordable zero- or low-emissions technologies are rapidly becoming available at airports. The TRB Airport Cooperative Research Program's pre-publicaton draft of ACRP Research Report 220: Guidebook for Developing a Zero- or L...

Most general aviation (GA) airports are minimally staffed and rarely employ environmental specialists, and the National Environmental Policy Act (NEPA) can be overwhelming to work through for those not familiar with the requirements. The TRB Airport Cooperative Research Program's ACRP Research Report 211: Guidance for Using the Interactive Tool for Understanding NEPA at General Aviation Airports , and the accompanying interactive tool that was developed, will help airport staff from GA airports understan...

The first edition of this report, in 2009, provided a comprehensive industry reference for the management of airport deicing runoff. The second edition has been wholly updated to reflect the latest industry practices. The TRB Airport Cooperative Research Program's ACRP Research Report 14: Deicing Planning Guidelines and Practices for Stormwater Management Systems, second edition , explores a wide array of practices designed to provide for the practical, cost-effective control of runoff from aircraft and ...

TRB’s Airport Cooperative Research Program (ACRP) Research Report 16: Guidebook for Managing Small Airports. Second Edition is designed to help airport practitioners, owners, operators, managers, and policymakers of small airports, who may have varying degrees of experience and backgrounds, to fulfill their responsibilities in such areas as financial management, oversight of contracts and leases, safety and security, noise impacts, community relations, compliance with federal and state obligations, facil...

Airports and the communities they serve view robust air service as an important element for economic well-being and overall quality of life. Incentive programs are often used to encourage airlines to maintain or augment service to a community. Recent airline industry trends, including airline consolidation, use of larger aircraft, the rise of ultra-low-cost airlines, and challenges with pilot supply as well as regulatory and policy developments, have affected the significance of these programs. The TRB A...
