This Research Brief provides highlights from the AAA Foundation for Traffic Safety’s 2024 American Driving Survey, which quantifies the daily driving of the U.S. population in 2024 and compares results to 2023 and 2022. Similar to 2023, this Research Brief analyzes the age of vehicles driven by the American public and explores differences by population […]
Road debris is a traffic safety concern for all road users. While there is no singular definition of road debris, it generally refers to any object on a roadway that does not belong in the driving environment.

An event data recorder (EDR) is defined in 49 CFR Part 563 to mean a device or function in a vehicle that records the vehicle’s dynamic time-series data during the time period just prior to a crash event (e.g., vehicle speed vs. time) or during a crash event (e.g., delta-V vs. time), intended for retrieval […]
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. […]
This annual report provides a glimpse of the work we have accomplished in 2025, including recognizing organizations we have collaborated with in recent times on research projects and our partner for the 2025 Safe Mobility Conference, the University of Wisconsin–Madison. Additionally, our newly established research groups are featured in this annual report, along with four […]
While it is important for older adults to maintain their mobility, age-related functional declines can impact driving abilities, with important implications for road safety. To better understand factors influencing the safe mobility of older adults AAAFTS commissioned the Longitudinal Research on Aging Drivers (LongROAD) study, a multisite prospective cohort study designed to generate empirical data […]
This report outlines how a modern approach to traffic safety can save lives and reduce injuries through targeted, evidence-based action. It describes how TRA can be used alongside other information to provide insight into road risk and how the methodologies used by the insurance industry have created a path forward that transportation officials, policy makers […]
For this fact sheet, urban boundaries are determined by the State highway departments and approved by the Federal Highway Administration (FHWA), and the areas outside those boundaries are described as rural. The State highway departments use the boundaries decided by the Census Bureau.1 This fact sheet describes rural or urban classification of the trafficway segment […]
