The Conference on Health and Active Transportation brought together leaders from the transportation and health disciplines to chart a course for the future of active transportation. TRB's Transportation Research Circular E-C264: Conference on Health and Active Transportation compiles comments of the plenary sessions and individual breakout sessions.

Knowing where people are at different times of the day potentially enables the design of airspace routes that minimize the environmental impact to a shifting population on the ground. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 48: Evaluating the Use of Spatially Precise Diurnal Population Data in Aviation Noise Studies examines the potential role of spatiotemporal pop...

Different choices in the budget assigned to road preservation and repair should be considered to find the optimal contribution of the road network to greenhouse gas (GHG) emissions mitigation and to meet targets set in the Paris Agreement on climate change. "Potential Contribution of Deflection-Induced Fuel Consumption to U.S. Greenhouse Gas Emissions,"  by Hassam Azarijafari, Jeremy Grego...

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 ma...

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 NCHR...

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...

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-publicatio...
