The importance of safety cannot be overstated and requires continued shifts in the approach to safety management within the public transportation industry. The TRB Transit Cooperative Research Program's pre-publication of TCRP Research Report 218: Characteristics and Elements of Non-Punitive Employee Safety Reporting Systems for Public Transportation compiles the best practices used in non-punitive employee safety reporting systems at transit agencies.

The TRB National Cooperative Highway Research Program's NCHRP Synthesis 551: Highway Hydraulic Engineering State of Practice documents significant changes in highway hydraulic engineering practices implemented by state departments of transportation (DOTs) over the past decade. The synthesis focuses on eight subtopics of highway hydraulic engineering: roadway drainage; culvert aquatic organism passage; bridge scour computations and countermeasures; advanced hydraulic modeling; regulatory requirements; flo...

Extreme weather events and a changing climate increasingly boost costs to transportation agencies and to the traveling public. While Departments of Transportation (DOTs) are taking into account changing climate and extreme weather when making infrastructure decisions, they typically are not using a formal set of tools or cost-benefit analyses (CBAs) to address climate resilience because they may be too time-consuming and expensive to conduct routinely. The TRB National Cooperative Highway Research Progra...

Cost-benefit analysis (CBA) is useful for climate change response and adaptation, and if used properly, it has great potential for long-range planning. CBA should help agencies navigate the spectrum of decisions from mitigation and greenhouse gas reduction to adaptation: where does investing public funds generate the most public good? The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 271: Guidelines to Incorporate the Costs and Benefits of Adaptation Measures in Preparation ...

The fixed-base operator (FBO) industry provides aeronautical services to a wide spectrum of aircraft operators at airports. The term FBO is defined by the FAA as “a business granted the right by the airport sponsor to operate on an airport and provide aeronautical services . . .” The most basic FBO offers its customers self-service fueling, as well as a set of core services such as use of hangars, ground services, and, sometimes, aircraft maintenance. The TRB Airport Cooperative Research Program's ACRP S...

The TRB Centennial Book is available for purchase in ebook or print format. In The Transportation Research Board, 1920–2020: Everyone Interested Is Invited , author Sarah Jo Peterson tells the story of how people and institutions created and have continued to shape TRB. In a compelling narrative accompanied by more than 150 images exploring the history of transportation and research, she argues that TRB can be best understood as an infrastructure—one that people purposely designed and devotedly maintained.

Utility companies are seeking to locate communications facilities and evolving wireless communication technology and its infrastructure in state right-of-way. The TRB National Cooperative Highway Research Program's NCHRP LRD 81: Legal Issues Concerning the Use of Transportation Facilities to Generate Revenue for State DOTs summarizes and provides a legal analysis of the legal issues related to a state DOT’s obligation to provide access to the state right-of-way for communication utilities, and a DOT’s op...

With increased connectivity between vehicles, sensors, systems, shared-use transportation, and mobile devices, unexpected and unparalleled amounts of data are being added to the transportation domain at a rapid rate, and these data are too large, too varied in nature, and will change too quickly to be handled by the traditional database management systems of most transportation agencies. The TRB National Cooperative Highway Research Program's NCHRP Research Report 952: Guidebook for Managing Data from Em...

Performance testing of asphalt mixtures is becoming more widespread for a variety of reasons and with a variety of testing devices. The tests results are sensitive to the procedures used in preparation of the specimens. Guidelines exist for conducting the tests; however, they do not all provide uniform or comprehensive direction for fabricating test specimens. The TRB National Cooperative Highway Research Program's NCHRP Synthesis 552: Practices for Fabricating Asphalt Specimens for Performance Testing i...

The zero‐emission bus (ZEB) market, including Battery Electric Buses and Fuel Cell Electric Buses, has seen significant growth in recent years. ZEBs do not rely on fossil fuels for operation and have zero harmful tailpipe emissions, improving local air quality. The increase in market interest has also helped decrease product pricing. The TRB Transit Cooperative Research Program's pre-publication draft of TCRP Research Report 219: Guidebook for Deploying Zero-Emission Transit Buses is designed to provide ...
