Amid growing demand for gas and diesel from the ongoing Middle East conflict and the traditional high-demand fall travel season, the Federal Motor Carrier Safety Administration has eased hours restrictions for fuel haulers. Eligible fuel haulers may drive up to 16 hours in a 24-hour period under a new federal waiver intended to give gasoline […]
Post-implementation evaluation (PIE) provides an opportunity to learn from past efforts and make better decisions in the future. By systematically examining the impacts of completed projects, agencies can identify proven strategies, refine business processes, and strengthen institutional knowledge for future initiatives. Evaluating project performance against its original goals and objectives creates a feedback loop that […]
The 2026 Safe Mobility Conference was held in Seattle from March 30 to April 1 and was co-hosted by the AAA Foundation for Traffic Safety and the University of Washington. Centered on the theme “Smarter Solutions, Safer Mobility,” the conference brought together more than 280 attendees from academia, government, industry, and nonprofit organizations. This publication […]
Pedestrian crashes are rising. What is driving the rise? And what cost-effective treatments can improve safety? TRB hosted a webinar on Tuesday, June 13, 2023 from 1:00 PM to 2:30 PM Eastern that examined pedestrian crash trends and analyze various contributing factors. Presenters also provided recommendations for cost-effective safety improvements throughout the roadway network. TRB […]
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 […]
This report provides an overview of the cultural environment of driving in the United States, explores drivers’ perceptions of road safety, and examines links between perceived neighborhood driving behaviors, self-appraisals of behavior and abilities, and perceived social stress on self-reported engagement in risky driving behaviors. Similar to previous Traffic Safety Culture Index reports, this edition […]
Speeding remains a serious threat to safe mobility, contributing to nearly 30% of motor vehicle fatalities. Despite this, the AAA Foundation’s Traffic Safety Culture Index shows that many drivers view speeding as less dangerous than other risky behaviors, while speeding remains both the most common and, for many, the only risky driving behavior they report. Although proven countermeasures such as automated speed enforcement […]
Security vulnerabilities in the Connected and Autonomous Vehicle (CAV) software can allow hackers to perform malicious actions ranging from draining batteries and taking control of the steering wheel to disabling the alarm system. CAV software is subject to several cyber-attacks including memory corruption, code injection, remote code execution, and malware attacks. This study develops a […]
The original scope of this work was intended to examine the relationship between changes in police traffic enforcement—particularly reductions in traffic stops—and roadway safety outcomes across multiple jurisdictions using a case-control design. Due to limitations in the availability of and trends in relevant data across sites, findings of the case studies presented in this report […]
Utilities are essential services that often occupy the public right-of-way along roads. While utility access benefits both service providers and the public, utility facilities can complicate highway construction, especially roadway expansion projects. Transportation agencies identify utilities requiring relocation through coordination with utility owners during project planning and design. However, no process or technology can guarantee […]
