The performance of flexible and rigid pavements is known to be closely related to properties of the base, subbase, and/or subgrade. Recent research studies, however, indicate the procedures contained in the American Association of State Highway and Transportation Officials (AASHTOs) design guidance need to be evaluated. TRB will host a webinar...
The systemic safety management approach is intended to address high frequency roadway crash types, but a traditional crash-history-based safety management approach can overlook individual locations.

Racism has been overt in transportation. For example, the segregation of races on intercity trains led to the infamous 1896 Plessy v. Ferguson separate but equal Supreme Court doctrine that stood for more than half a century. While many discriminatory policies have been reversed by the courts and in constitutional amendments, their impacts on...
The University of Arkansas and California State University, Long Beach diversity and inclusion programs have been built to foster enduring change with an eye toward seeing real benefits five to 10 years down the road. This feature article is from the May-April 2021 issue of TRB's magazine, TR News (Issue 333). TR News is TRB's bimonthly...
Bridge waterways commonly narrow or constrict natural channels, forcing water to flow through a contracted area, thereby increasing the magnitudes of velocity and turbulent kinetic energy of flow passing through the waterway. If these increases cause erosion of the waterway boundaries, the contracted section may scour. The TRB National...
