Pedestrian safety at night_NCHRP RR 1157.JPG

Walking is an important part of a healthy, sustainable transportation system. Yet walking is too often inaccessible, uncomfortable, or unsafe as a practical option for large numbers of people because of traffic risk, discomfort, or inconvenience. Multilane roadways, higher design and posted speeds, and a lack of safe and convenient pedestrian walking and crossing facilities and operations, even at known attractors such as bus stops and grocery stores are consistently associated with pedestrian fatalities in the United States. The risk is much higher at night. Between 2018 and 2022, 76% of U.S. pedestrian crash fatalities occurred in darkness. NCHRP Research Report 1157: Strategies to Improve Pedestrian Safety at Night: A Guide and NCHRP Web-Only Document 430: Improving Pedestrian Safety at Night, were released this week by TRB's National Cooperative Highway Research Program.

Traffic safety public awareness and education efforts are two countermeasures that traffic safety professionals, including those working at state highway safety offices, employ to improve roadway user safety. These efforts are intended to share messaging that will raise awareness of dangerous roadway behaviors, increase knowledge of the impact of these behaviors and safer alternatives, change attitudes about both those behaviors and the alternatives, and ultimately, change those behaviors. BTSCRP Research Report 14: Evaluating Traffic Safety Campaigns: A Guide, and BTSCRP Web-Only Document 7: Objectives, Components, and Measures of Effective Traffic Safety Public Awareness and Education Efforts, were released this week by TRB's Behavioral Traffic Safety Cooperative Research Program.

October Spotlight: Resilience

University of California Pavement Research Center's Stephanus Louw explores the low-volume road resilience to anticipate, prepare for, respond to, and recover from extreme adverse weather impacts in TR News 355 (Fall 2025). He notes the role of vulnerability assessments, design strategies, green infrastructure, and more.

In 2023, the U.S. Department of Transportation’s Bureau of Transportation Statistics launched the Transportation Vulnerability and Resilience (TVAR) Data Program in response to Investing in Transportation Resilience: A Framework for Informed Choices from TRB of the National Academies in 2021. The report recommended an analytic framework that incorporated detailed inventories of existing and planned assets, assessing the characteristics and likelihood of future natural hazards, then putting those together to measure and assess resilience.

TRB In the News
  • As the federal government shutdown continues, staffing shortages among air traffic controllers is impacting travel. A Vermont NBC affiliate highlights TRB's air traffic controller staffing consensus report, noting that controller staffing recovery would benefit from uninterrupted hiring and training activities.
  • Praveen Edara at the University of Missouri and his team launched Work Zone Assistant, an AI-powered chatbot to ensure work zones comply with federal safety requirements. The team presented early findings of Work Zone Assistant at the 2025 Transportation Research Board’s Annual Meeting.
