TRB will host a webinar on Monday April 12, 2021 from 1:00 to 2:30 PM Eastern to discuss the current usage and demand of LWC in the United States. Presenters will provide an overview of the...
Transit reliability is critical to the operation and attractiveness of public transportation services. TRB is hosting a webinar on Tuesday, April 13, 2021 from 1:00 to 2:30 PM Eastern that will clarify what factors determine bus reliability. Presenters will discuss relevant definitions, measurement tools, and strategies to improve reliability....
Chemical soil stabilization designers rely on either empirical data or past experience coupled with engineering tests. TRB will host a webinar on Thursday, April 14, 2021 from 1:00 to 3:00 PM Eastern to address the importance of considering soil mineralogy together with engineering tests to identify the suitable type and application rate of...
Implementing AASHTOWare Pavement ME (also known as the Mechanistic-Empirical Pavement Design Guide, or MEPDG) as a design procedure is a challenge. The MEPDG can be used for new construction as well as for pavement rehabilitation, and provides design solutions related to knowledge resources and data. TRB will host a webinar on Monday, April, ...

TRB's National Cooperative Highway Research Program (NCHRP) has released a request for proposals to develop a handbook on selecting and implementing methods to temporarily deter and/or exclude bats from transportation structures ahead of and during construction and maintenance activities. The handbook will describe methods that are (1) sensitive...
Today, transit agencies gather and manage more data than ever. However, data processing, exploration, the development of performance metrics, and communicating decisions are often fragmented and scattered across many departments. The TRB Transit Cooperative Research Program's TCRP Synthesis 153: The Transit Analyst Toolbox: Analysis and...
Light emitting diode (LED) technology has revolutionized the lighting industry. The dimming and instant-on capabilities of these light sources along with their high efficiency have allowed lighting designers to overcome some of the limitations of previous technologies, particularly in roadway lighting environments. However, concerns related to the ...
Run-off-road traffic crashes account for almost one-third of the deaths and serious injuries each year on U.S. highways. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 296: Guidelines for Cost-Effective Safety Treatments of Roadside Ditches provides new proposed design guidance for the configuration of ditches...
Increased use of zero emission vehicles (ZEVs) presents the greatest opportunity to improve the energy efficiency of light-duty vehiclesi.e., passenger vehicles and light trucksover the period of 2025-2035, says a new congressionally mandated report from the National Academies of Sciences, Engineering, and Medicine. The U.S Department of...
