Construction of load-carrying geosynthetic-reinforced bridge abutments are surging worldwide. The design directly supports the load of bridge girders without the need of deep foundation. TRB is hosting a webinar on Tuesday, May 26, 2020 from 2:00 to 4:00 PM Eastern that will provide an overview, comparison, and discussion of methodologies used in the design of such bridge abutments. They have the potential of alleviating the “bump at the bridge,” expediting construction, and requiring comparatively smal...

TRB released a straight-to-recording series in April that presents highlights and findings of the NCHRP Domestic Scan 16-02 on Landscape Design Practices for Roadside Water Management .

The videos are available on-demand at no charge. Presenters: Garrett...

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...

Global business and tourism depend heavily on the efficient operation of airports and movement of passengers, baggage, and cargo across many areas. With increasing demand and connectivity requirements for airports comes the need for more sophisticated simulation and modeling tools to validate design assumptions. Furthermore, airport design and planning decisions have significant impacts on policy and major capital improvement decisions, which can be supported by simulation and modeling tools at many leve...

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...

“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,...

As demand for air travel grows, airport-related emissions are increasing and airports are challenged to reduce associated environmental impacts. In response, expanded regulatory programs and global climate protection initiatives are being developed that require the aviation industry—including U.S. airports—to implement new, clean technologies and to modify operational practices to reduce emissions. One effective option for reducing the emissions associated with aircraft auxiliary power units (APUs) and d...

Barriers, berms, buildings, and natural terrain may affect the propagation of aircraft noise by shielding or reflecting sound energy. If terrain and manmade structures obstruct the line‐of‐sight between the source and the receiver, then sound energy will be attenuated at the receiver. This attenuation increases with the terrain and structures’ size and proximity to either the source or the receiver. If gaps exist in the terrain or structures, then the potential benefits of acoustical shielding will be su...

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.
