The data in these State by State Abstracts contain State-submitted data to FHWA on: motor fuel use, driver licensing, vehicle registration, State and local financing, land area, population, and vehicle miles of travel.
This project identified interchange configurations that account for at least 75 percent of those considered in Interchange Access Requests (IARs). The project team surveyed Federal Highway Administration (FHWA) division offices to determine the most common interchange configurations considered and constructed and the planning-level factors consider

Traditional safety modeling efforts primarily focus on accurately estimating crash frequencies or rates. The true relationships between crashes and potential causal factors are not always easily discernible from safety models. While a model consisting of multiple causal factors may produce accurate estimates of crash measures, it may not accurately

The Makah Tribe has resided in a remote oceanside region in the northwestern tip of Washington State for thousands of years and has had to adapt to a changing environment to survive. The Tribe is now engaged in various climate change and resilience projects to ensure the community’s long-term ability to live safely in their Tribal lands.
As climate change continues to threaten wildlife resiliency, measures must be taken to ensure animals can migrate for their survival. The collision mitigation measures examined in this study will help to improve climate sustainability and simultaneously reduce crashes that can lead to property damage as well as driver injury and death throughout th

The Michigan Department of Transportation (MDOT) plans to replace the Lafayette Avenue Bridge over the Saginaw River in Bay City, MI. Hydraulic scour analysis of the planned bridge replacement resulted in deep scour depths, which MDOT believed were excessive due to a subsurface layer of cohesive soil that existed across the bridge site. MDOT reache

This provides information regarding technical support for Interactive Highway Safety Design Model (IHSDM). The Federal Highway Administration (FHWA) has discontinued IHSDM software development. However, FHWA will continue to provide free technical support via Geometric Design Laboratory (GDL) staff through at least September 2024, but essentially a

Researchers for this study developed improved video processing algorithms that can identify more complex behavior and actions of individuals (i.e., pedestrians, drivers, bicyclists) in various traffic situations. The research team wanted to build on existing video-processing algorithms that can identify basic behavior, “primitives” (such as when a

Merger and acquisition (M&A) activity, particularly in the transportation materials and construction industry, is analyzed relatively infrequently. However, this activity can significantly affect project completion, market control, and pricing. In many cases, collaboration between firms with similar goals and corporate growth strategies in a health

This technical report describes the modeling analysis conducted to support the 2023 Federal Highway Administration (FHWA) carbon monoxide (CO) categorical hot-spot finding for intersections using MOVES31 and CAL3QHC.2 The finding does not apply to California, which uses EMFAC3 for its emissions model. The 2023 CO categorical finding replaces the si

Safety is a top priority of the U.S. Department of Transportation (USDOT). In 2020, even though the volume of traffic was down overall, 38,824 people still died in motor vehicle crashes, and an estimated 2.28 million were injured.1 To reach the USDOT’s safety goals, the transportation sector needs to work together to identify and implement safety s
