ACRP Research Report 198: Wetland Mitigation, Volume 2, A Guidebook for Airports explores how to mitigate potential impacts to wetlands from airport construction, expansion, and safety improvements. The report addresses a broad range of issues, including: • Concerns over the creation of potential wildlife hazards; • Existing requirements, which may or may not be conflicting; • Impact to existing and future airport development; • Airport considerations of cost and logistics in developing mitigation and re...

TRB’s Airport Cooperative Research Program (ACRP) Research Results Digest 28: Thought Leader Forum Summary—Emerging Issues for ACRP summarizes a January 30, 2019, forum to identify the most important issues facing the airport industry within the next 5 to 10 years. The goal of this exercise was to engage the ACRP’s Airport Operations Committee (AOC) directly with other thought leaders in the industry to identify and define high-level emerging critical issues that impact, or will soon impact, the airport ...

TRB’s Airport Cooperative Research Program (ACRP) Research Report: 194: Using Disaggregated Socioeconomic Data in Air Passenger Demand Studies explores the potential benefits of using disaggregated socioeconomic data, such as regional household income distributions and air passenger and travel survey data, for air passenger demand studies. Aviation demand is strongly correlated to socioeconomic activity, and analysts typically use aggregate socioeconomic data, such as gross regional product or average re...
