November 18-22 is Crash Responder Safety Week
The Alabama Department of Transportation (ALDOT) is urging drivers to stay alert and slow down for first responders working on Alabama’s roads during Crash Responder Safety Week, Nov. 18-22. Each year, ALDOT and emergency responders statewide join a national effort to improve roadway safety for first responders, from police to EMS and tow truck drivers. […]
Does Older Adults’ Self-Regulation of Driving Improve Safety?
Self-regulation is the act or process of modifying one’s driving in response to an awareness of one’s declining abilities. Two common forms are (1) strategic self-regulation, or decisions made prior to one’s actual driving, and (2) tactical self-regulation, decisions made while driving in response to circumstances of the environment. Rapid Deceleration Events (RDEs), commonly known […]
FIRST RESPONDER DATA ASSESSMENT: STRUCK-BY CRASHES
This report documents the effort by the Federal Highway Administration (FHWA) Office of Safety and Operations Research & Development and the FHWA Office of Operations to assess current data sources, to compile existing data, to review gaps, and to propose a data collection strategy that will start to quantify the occurrence of responder struck-by crashes. […]
2023 Urban Congestion Trends
Federal Highway Administration’s (FHWA’s) Work Zone Management Program engages with State Departments of Transportation (DOTs) and conducts research to understand work zone mobility performance measurement best practices, challenges, and opportunities. The information gathered increases awareness of data, tools, and methods for systematic work zone performance measurement. Topics of interest include use of probe data and […]
GHSA and State Farm Team Up to Help Parents Raise Distraction-Free Kids
Distracted driving is one of the most dangerous – but common – activities on the road. To help change the culture and create a new social norm, the Governors Highway Safety Association (GHSA) and State Farm® have partnered to develop a new website to help parents and guardians raise a generation of distraction-free, safe road […]
Integration of vehicle operating cost and emission models
The NZVOC model and the VEPM were reviewed in terms of each model’s purpose, scope, and data inputs and outputs and their update frequency, and common and unique elements were identified. From the review, several potential opportunities were identified to align similar aspects of the models. These include aligning the current and forecasted vehicle fleet, […]
ELECTRIC VEHICLES AND THE ENERGY TRANSITION
The growth of electric vehicles (EVs) raises new challenges for electricity systems. We implement a field experiment to assess the effect of time-of-use (TOU) pricing and managed charging on EV charging behavior. We find that while TOU pricing is effective at shifting EV charging into offpeak hours, it unintentionally induces new and larger “shadow peaks” […]
Early Estimate of Motor Vehicle Traffic Fatalities for the First Half of 2024

Corrosion-Induced Major Tendon Failures in Post-Tension (PT) Concrete Bridges
There are two types of PT tendons—bonded or unbonded—depending on the timing of installing the duct, tensioning the strands, and filling the ductwith grout. Injected filler materials afford additional corrosion protection by providing physical barriers to water and air, i.e., oxygen and carbon dioxide.Cementitious grout can also be beneficial, providing a high-pH environment to form […]
