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...

I am doing a materials internship this summer in Wichita, Kansas at Cessna Aircraft (now part of Textron Aviation), in the metals group of the Materials and Processes Engineering division.  My internship requires me to inspect returned parts […]

Demand-responsive transportation (DRT) can produce benefits — fewer empty seats, lower cost per passenger, less delay for customers — to both passengers and transportation service providers, particularly the public and private nonprofit agencies that finance DRT services with public funds. The TRB Transit Cooperative Research Program's TCRP Research Report 210: Development of Transactional Data Specifications for Demand-Responsive Transportation presents a transactional data specification for DRT to faci...

TRB has been closely monitoring the evolving situation related to the coronavirus disease (COVID-19) outbreak.

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) Report 150: NextGen for Airports, A Primer broadly address potential airport impacts and include background information so that airport personnel can discern which NextGen programs will impact them and how.

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 ...

TRB's Airport Cooperative Research Program (ACRP) WebResource 5: Tools and Case Studies for NextGen for Airports is a companion to the five-volume ACRP Report 150: NextGen for Airports. It provides downloadable engagement materials from the NextGen Outreach Toolkit, discussed in Volume 2: Engaging Airport Stakeholders, and the Public Information Toolkit, discussed in Volume 3: Resources for Airports. A table that identifies the volume and page number of all case studies discussed in the five volumes is a...

TRB's Airport Cooperative Research Program (ACRP) Research Report 191: A Primer to Prepare for the Connected Airport and the Internet of Things introduces the concept of the Internet of Things (IoT) within the airport environment to leverage current and emerging technologies. IoT can be used to provide information and services to airport passengers with current and evolving technologies. Airports, airlines, and other stakeholders can use these innovative technologies and data to enhance the user exp...

“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 a reliever airport for the Phoenix Sky Harbor International Airport, Phoenix–Mesa Gateway Airport must keep track of information for nearly 300,000 aircraft operations and 1.4 million passengers a year. To meet this challenge, the airport developed an innovative, digitally connected solution with the help of ACRP Research Report 182: Guidancefor Planning, Design, and Operationsof Airport Communications Centers . The TRB Airport Cooperartive Research Program's ACRP Impacts on Practice 182: Redesigning ...

The unmanned aircraft systems (UAS) industry is on the cutting edge of aviation innovation. Airports, including tenants and contractors, are discovering the benefits of UAS to their operations and bottom line. Yet, with the diversity of UAS applications at airports, there has been a lack of relevant industry data on this topic to inform the airport industry on current practices. The TRB Airport Cooperative Research Program's ACRP Synthesis 104: Current Landscape of Unmanned Aircraft Systems at Airports s...

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...

Airports must maintain a safe and efficient facility while considering environmental impacts. Though traditional environmental challenges such as noise and water quality remain, several new themes are emerging, including energy management, sustainability, resiliency, and wildlife management. Airports will need guidelines and practices to help them address these pressing issues, and the first step in the process is to identify knowledge gaps and research needs. The TRB Airport Cooperative Research Program...
