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...

The TRB Standing Technical Committee on Bicycle Transportation has been in existence for about 45 years, founded in 1974 as the Bicycling and Bicycles Committee. We had an early name change to the Committee on Bicycling and Bicycle Facilities shortly after our birth and became the Bicycle Transportation Committee in 1996. The committee's existence closely parallels the history of bicycle transportation research in the United States. Very little was done prior to the mid-1970s, when a surge of interest in...

The report includes case examples from six cities: Santa Monica, Denver, Austin, Chicago, Dallas, ...

TRB’s Airport Cooperative Research Program (ACRP) Research Report 200: Using GIS for Collaborative Land Use Compatibility Planning Near Airports offers guidance for using Geographic Information Systems (GIS) as a collaboration tool to encourage compatible land use around airports. The report is designed to help airport and community planners seeking to work together to protect existing and future airport development as well as maintain safety and improve quality of life for those living and working near ...

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...

In the days of coronavirus disease (COVID-19), we are seeing a reduction in overall traffic volumes and crash-related injuries and fatalities.

Airports continually balance demands to improve infrastructure within the realities of available budgets. Green revolving funds (GRFs) offer an alternative approach for investing in projects that generate operational savings. These funds work by tracking verified cost reductions from implemented actions, and then transferring those savings to a reserve that provides capital for future qualified projects such as energy system upgrades. A number of universities have managed GRFs for over a decade. Municipa...
