Speeding contributes to nearly one-third of all roadway fatalities, and this proportion has remained largely unchanged for the past decade. Since roadway departure, intersection, and pedestrian and bicycle crashes have been identified by the Federal Highway Administration (FHWA) as the three areas with great potential to reduce fatalities, States are being encouraged to integrate speed management into these three safety focus areas.

Speeding contributes to nearly one-third of all roadway fatalities, and this proportion has remained largely unchanged for the past decade. Since roadway departure, intersection, and pedestrian and bicycle crashes have been identified by the Federal Highway Administration (FHWA) as the three areas with great potential to reduce fatalities, States are being encouraged to integrate speed management into these three safety focus areas. To assist agencies with integrating speed management into their policies, practices, and safety plans, this report presents information on national speeding-related crash trends, promotes a speed-related crash data analysis approach, and recommends strategies and initiatives for integrating speed management into an agency's overall policies, as well as their roadway departure, intersection, and pedestrian/bicyclist safety programs.

Written for undergraduate students and new transportation professionals, this textbook introduces the basics of traffic safety needs identification, countermeasure selection, and implementation of treatments to reduce the number of roadway crashes and resulting injuries and fatalities. It describes the current state of the practice regarding crashes occurring at intersections, work zones, and as the result of lane departures.

Improving safety is a top priority for the U.S. Department of Transportation, and the Federal Highway Administration (FHWA) remains committed to reducing highway fatalities and serious injuries on our Nation's roadways through the use of proven safety countermeasures, including Road Diets. Along with the development of the Road Diet Informational Guide, the FHWA Office of Safety commissioned a series of 24 case studies highlighting Road Diet implementations throughout the United States.

Improving safety is a top priority for the U.S. Department of Transportation, and the Federal Highway Administration (FHWA) remains committed to reducing highway fatalities and serious injuries on our Nation's roadways through the use of proven safety countermeasures, including Road Diets. Along with the development of the Road Diet Informational Guide, the FHWA Office of Safety commissioned a series of 24 case studies highlighting Road Diet implementations throughout the United States. The aim of this document is to provide State and local agencies and Tribal governments with examples and advice that can assist them in planning and implementing Road Diets in their own jurisdictions.

A classic Road Diet converts an existing four-lane undivided roadway segment to a three-lane segment consisting of two through lanes and a center two-way left turn lane (TWLTL). This Informational Guide includes safety, operational, and quality of life considerations from research and practice, and guides readers through the decision-making process to determine if Road Diets are a good fit for a certain corridor. It also provides design guidance and encourages post-implementation evaluation.

This manual provides information on the costs and benefits of safety treatments on high-risk rural roads (HRRR). Agencies can use this manual to determine the following information on the treatments: Safety benefits; Cost effectiveness comparison of safety treatments; Applicability of treatment deployment with respect to identified need; and Initial and reoccurring maintenance costs associated with countermeasure installation. In addition, this manual provides information on the decision-making… Show more

This document serves as an introduction to and guide for evaluating the safety, design, and operations of signalized intersections. It also provides tools to deliver better balanced solutions for all users.

This guidance shares work zone safety-related data analysis methods that are effective in identifying safety improvement strategies and developing work zone crash reduction programs and analysis techniques.

Road safety audits (RSAs) of temporary work zones can yield benefits like RSAs on permanent roadways
