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 […]
Transportation planning agencies and officials face a rapidly evolving technical, policy, legislative, and procedural environment. Agency professionals often seek the guidance of peers and experts to help them effectively address these challenges. Challenges include managing the demand for new transportation technologies and services within the confinements of existing streets, navigating the effects of growing e-commerce […]
Examining the behavior of drivers to encourage safe operation of vehicles is one of the core research areas at the AAA Foundation for Traffic Safety. This technical report presents research findings on one such driver behavior, distracted driving, because it remains a significant traffic safety concern. Technology-based countermeasures such as smartphone blocking features can effectively […]
State departments of transportation (DOTs) undertake numerous bridge replacements annually. Specific replacements present unique challenges among these projects due to location restrictions, mobility implications, design characteristics, and environmental constraints. NCHRP Synthesis 645: Construction Strategies and Techniques for Planned Bridge Replacements in Complex Scenarios, from TRB’s National Cooperative Highway Research Program, documents practices and decision-making used […]
Public agencies nationwide are benefiting from ever-evolving advancements in traffic management operations, specifically through intelligent transportation systems (ITS). These transportation and traffic management systems use cutting-edge information and communication technologies to improve safety, efficiency and sustainability of their networks, thereby improving safety, reducing traffic congestion and enhancing driver experiences. Transportation leaders interested in implementing or […]
Dial-a-ride and fixed-route transit options are some of the ways that microtransit services have traditionally been implemented in rural areas. App-based booking and dynamic routing are among the newer offerings transit agencies are exploring to provide greater flexibility and more spontaneous options for users. TCRP Synthesis 178: Microtransit Solutions in Rural Communities: On-Demand Alternatives to […]
The Department of Transportation’s Federal Highway Administration (FHWA) provides funding for states to improve safety at public crossings through the Railway-Highway Crossings Program (RHCP). GAO found that states used RHCP funding to address safety risks. For example, states added or upgraded existing equipment at crossings—such as bells, lights, and gates—from 2019 through 2023. During the […]
The availability of large-scale, high-resolution, and consistently collected road data will improve the safety of all road users. The use of artificial intelligence (AI), machine learning (ML), and big data is key in providing the information needed to power data-driven, public, and proprietary safety analysis tools, as well as predictive and other systemic safety tools.
