TRB's Airport Cooperative Research Program (ACRP) has issued a request for proposals to develop a primer and guidebook to help airport operators understand and respond to homeless people at their facility. Proposals are due January 28, 2021 at 5:00 PM Eastern.

TRB's Airport Cooperative Research Program (ACRP) has issued a request for proposals to develop: (1) a guidebook of recommended practices for determining the source(s) of per- and polyfluoroalkyl substances (PFASs) detected in soil and water on or near an airport and (2) a primer for airport practitioners describing PFAS source attribution concepts and techniques in lay terms. Proposals are due February 2, 2021 at 5:00 PM Eastern.

TRB's Airport Cooperative Research Program (ACRP) has issued a request for proposals to develop a guidebook to help airports of various levels of activity, resources, and subject matter expertise develop a plan to manage per- and polyfluoroalkyl substances (PFASs) at their facilities. Proposals are due February 2, 2021 at 5:00 PM Eastern.

TRB's Airport Cooperative Research Program (ACRP) has issued a request for proposals to
(1) Identify and develop potential viable systems, configurations, and technologies for arresting aircraft at all types and sizes of airports that are not covered by existing patents. Solutions could consider but should not be limited to technical alternatives presented under ACRP Report 29: Developing Improved Civil Aircraft Arresting Systems that could be further developed. In addition, the research should include an assessment of economically feasible solutions applicable to GA airports and
(2) Develop a model to evaluate and assess the characteristics of the proposed materials or systems to demonstrate its viability as an acceptable equivalent runway safety area. It should include physical material and or system testing. Proposals are due February 17, 2021 at 5:00 PM Eastern.

TRB's Airport Cooperative Research Program (ACRP) has issued a request for proposals to create a guidebook that (1) identifies and evaluates alternative methods for obstruction related data collection and analysis, and (2) includes strategies that effectively monitor and manage tree growth in and around airports. The guidebook should be applicable to different types, locations, and sizes of airports. Proposals are due February 24, 2021 at 5:00 PM Eastern.
