Automated traffic signal performance measures (ATSPMs) provide an alternative to traditional signal timing and have been shown to improve operations at signalized intersections by reducing split failures, arrivals on red, red-light running, and delays. Although not a fully adaptive solution, ATSPMs allow agencies to make near real-time signal timing adjustments based on field data, influencing […]
Black ice, a nearly invisible hazard causing over 10% of weather-related crashes in the US, poses significant risks to roadway safety. Current measures like stationary Road Weather Information sensors (mRWIS) and cautionary signs improve awareness, but have limitations. Mobile Advanced Road Weather Information Sensors (MARWIS) offer enhanced, cost-effective, and real-time data collection at highway speed […]
A National Action Plan for School Bus Safety includes specific recommendations for State Highway Safety Offices (SHSOs), law enforcement, educators, school districts, bus drivers, the private sector, autonomous vehicle providers, roadway safety advocates and the judiciary.

More than 6,300 people died in suspected drowsy driving crashes in 2023 – ten times higher than the 633 deaths officially reported in federal statistics. GHSA’s comprehensive analysis uncovered this hidden toll by cross-referencing multiple sources, including the Fatality Analysis Reporting System and the Crash Investigation Sampling System. This massive gap exists because fatigue, unlike alcohol or […]
Urban streets are increasingly complex environments where diverse transportation modes like cars, bicycles, pedestrians, micromobility, and emerging automated vehicles, interact within constrained spaces. Traditional design practices, guided by qualitative policies such as Complete Streets, often lack the quantitative foundation needed to evaluate trade-offs between efficiency, equity, and safety. This research introduces a data-driven framework to […]
One of the promising opportunities offered by AI to support the decarbonization of electricity grids is to align demand with low-carbon supply. We evaluated the effects of one of the world’s largest AI managed EV charging tariffs (a retail electricity pricing plan) using a large-scale natural field experiment. The tariff dynamically controlled vehicle charging to […]
Virtual public involvement (VPI), defined by the Federal Highway Administration as “the use of digital technology to engage individuals or to visualize projects or plans,” is now an essential part of public participation in transportation planning and project development. VPI has reduced participation barriers for many people while creating challenges for others. Although VPI was […]
Electric cars have soared in popularity in the wake of high gasoline prices. While improvements in vehicle battery technology have led to increased battery range, consumers are still left wondering how long they can expect their vehicle battery to last. After all, the battery pack is the most expensive part of an electric car, with […]
Some Walmart customers in 19 states, including Alabama, will soon notice a change in their store’s parking lot. The nation’s largest retailer is stepping up the installation of charging stations for electric vehicles. First announced in 2023, the plan includes building EV fast-charging stations at Walmart and Sam’s Club locations coast to coast by 2030. EV […]
Behavioral traffic safety messaging aims to inform, persuade, and motivate specific groups of road users to modify risky behaviors, with the goal of improving road safety and reducing traffic-related injuries and fatalities. These campaigns address numerous behaviors among both motor vehicle drivers and vulnerable road users across a wide range of demographics. Regardless of the […]
