The 2025 Safe Mobility Conference was held in Madison, Wisconsin, from April 7 to April 9, in partnership with the University of Wisconsin–Madison. The event brought together a diverse group of transportation stakeholders, including industry experts, academic researchers, and practitioners from governmental agencies, with the goal of fostering collaboration and building partnerships. The conference proceedings […]
EPA and the U.S. Department of Energy (DOE) have helped fund nondiesel school buses through four programs—three in EPA and one in DOE. EPA’s programs provide grants, rebates, or loans to help pay for less polluting school buses, such as those fueled by propane or electricity. DOE’s program has offered grants for energy improvements, including […]
The U.S. scientific enterprise has produced countless discoveries that have led to significant advances in technology, health, security, safety, and economic prosperity. However, concern exists that excessive, uncoordinated, and duplicative policies and regulations surrounding research are hampering progress and jeopardizing American scientific competitiveness. Estimates suggest the typical U.S. academic researcher spends more than 40 percent […]
NCHRP Web-Only Document 428: Quality Management for Digital Model–Based Project Development and Delivery, from TRB’s National Cooperative Highway Research Program, addresses two key challenges for state departments of transportation and other highway agencies: the use of 3D models as a new way to review construction designs and the review of the 3D models themselves. Quality […]
A new report from the Governors Highway Safety Association and Cambridge Mobile Telematics urges public officials to support and advance predictive analytics to prevent traffic deaths before they happen, marking a fundamental shift in how road safety is approached. With more than 200,000 deaths on U.S. roads since 2020, A Data-Driven Action Plan for Safer Roads presents […]
Demand response transportation (DRT) providers have consistently looked for operational designs and mechanisms to improve service efficiencies and lower operational costs. DRT services, which include ADA (Americans with Disabilities Act) complementary paratransit and general public DRT services, such as advance reservation dial-a-ride services and ondemand microtransit services, are inherently less efficient to operate due to […]
Researchers, policymakers, practitioners, and transportation-industry leaders are exploring how additive manufacturing (commonly referred to as 3D printing) and construction technologies can accelerate innovation in transportation infrastructure. Among the impacts being evaluated are supply chains, logistics, infrastructure resilience, and workforce development. TRB Conference on Advancing Additive Manufacturing and Construction in Transportation
The intermodal travel experience has changed significantly over the past two decades and continues to evolve. The broad adoption of digital technologies has altered how customers plan, book, and pay for travel and navigate spaces. Those that plan, build, and manage intermodal passenger facilities—such as airports, transit centers, rail and bus stations, and ferry and […]
Recent growth in AI capabilities has spurred a corresponding rise in public interest. Developments in generative AI—which can create text, images, audio, video, and other content when prompted by a user—have revolutionized how the technology can be used in many industries. However, generative AI has risks such as spreading misinformation and presenting national security and […]
The Safe System approach is a holistic approach that provides a framework for making the U.S. national transportation system safer. It is based on building and reinforcing multiple layers of protection to prevent crashes from happening and minimize the harm caused when crashes occur. This safety approach differs from conventional ones because it focuses on […]
