TRB's E-Circular 232: Automated Vehicle Symposium 2017: Summary of a Symposium highlights the themes from an event that took place on July 11–13, 2017 in San Francisco, California. The event explored the development, testing, building, and deployment of autonomous vehicles (AVs). The 2017 AVS provided the opportunity for communication, collaboration, and information sharing on a wide range of topics, including potential public policy, safety and security, ethical, and equity concerns, as well as technolo...

TRB's National Cooperative Highway Research Program (NCHRP) Research Report 875: Guidance for Evaluating the Safety Impacts of Intersection Sight Distance is a resource for practitioners involved in the planning, design, operations, and traffic safety management of stop-controlled intersections. It provides information on how to estimate the effect of intersection sight distance (ISD) on crash frequency at intersections and describes data collection methods and analysis steps for making safety-informed d...

TRB's National Cooperative Highway Research Program ( NCHRP) Web-Only Document 228 : Safety Impacts of Intersection Sight Distance documents the methodology and presents the results from NCHRP Research Report 875 : Guidance for Evaluating the Safety Impacts of Intersection Sight Distance. It provides  the underlying research on estimating the safety effects of intersection sight distance (ISD)  at stop-controlled intersections. To establish the relationship between ISD and safety at stop-contro...

The National Academies of Sciences, Engineering, and Medicine has released a report that identifies challenges to establishing a real-time system-wide safety assurance (RSSA) system and the high-priority research that should be implemented by the National Aeronautics and Space Administration (NASA) and other interested parties in government, industry, and academia to expedite development of such a system. RSSA is one of six focus areas for the NASA aeronautics program. NASA envisions that an RSSA system ...

To keep pace with accelerating rate of research distribution, the Transportation Research Record: Journal of the Transportation Research Board is now publishing articles as soon as they are finalized. The latest papers to be published are as follows: Use of a Laser Diffractometer to Obtain the Particle Size Distribution of Fine-Grained Soils Interstate Speed Profiles Conditioning and Testing Protocol Combinations to Detect Asphalt Mixture Damage Safety Evaluation of the SafetyEdge Treatment for Pavement ...

TR Circular E-C229: 10th SHRP 2 Safety Data Symposium: From Analysis to Results explores the October 6, 2017 symposium that served as a forum for the exchange of ideas about uses and methods for the SHRP 2 Safety Data Program and identified lessons learned from working with the data. This symposium focused on safety data analysis, results, and applications to help researchers and practitioners learn more about safety data applications.

The full edition of the September-October 2017 TR News magazine is now available. Transportation systems' resilience is the theme of feature articles in this issue. Authors describe lessons learned in planning, engineering, and operations management with regards to resilience; discuss supply chain business continuity; identify techniques for evacuation and emergency transportation; examine the role of social capital in transportation; and examine how to think about resiliency in future research endeavors...

TRB's Special Report 325: Safely Transporting Hazardous Liquids and Gases in a Changing U.S. Energy Landscape reviews how the pipeline, rail, and barge industries have fared in safely transporting the increased volumes of domestically produced energy liquids and gases. The report, sponsored by TRB, reviews the safety record of the three transportation modes in moving these hazardous shipments and discusses key aspects of each mode’s safety assurance system. The report urges the U.S. Department of Transpo...

TRB Special Report 324: Designing Safety Regulations for High-Hazard Industries, examines key factors relevant to government safety regulators when choosing among regulatory design types, particularly for preventing low-frequency, high consequence events. In such contexts, safety regulations are often scrutinized after an incident, but their effectiveness can be inherently difficult to assess when their main purpose is to reduce catastrophic failures that are rare to begin with. Nevertheless, regulators ...

The National Academies of Sciences, Engineering, and Medicine has released a report that examines which interventions (programs, systems, and policies) are most promising to prevent injuries and death from alcohol-impaired driving, the barriers to action and approaches to overcome them, and which interventions need to be changed or adopted. This report makes broad-reaching recommendations that will serve as a blueprint for the nation to accelerate the progress in reducing alcohol-impaired driving fatalit...
