This document presents a synthesis of current information and operating practices related to roadside safety and is developed in metric units. The roadside is defined as that area beyond the traveled way (driving lanes) and the shoulder (if any) of the roadway itself. The focus of this guide is on safety treatments that minimize the likelihood of serious injuries when a driver runs off the road. This guide replaces the 1989 AASHTO "Roadside Design Guide."

This roadside safety design package has been developed to satisfy a need for training in this area. It is hoped that all persons involved in the design, construction, operation, and maintenance of highways will become familiar with the concepts contained in the program. The concepts and practices discussed come from those contained in the AASHTO publication, "Highway Design and Operational Practices Related to Highway Safety". They are discussed in considerable depth in this program and should provide a good working knowledge of roadside safety design. Much of the program is oriented around freeways; however, the principles apply equally toward the lower order highway.

This guide replaces the 1984 publication entitled An Informational Guide for Roadway Lighting. It has been revised and brought up to date to reflect current practices in roadway lighting. The guide provides a general overview of lighting systems from the point of view of the transportation departments and recommends minimum levels of quality. The guide incorporates the illuminance and luminance design methods, but does not include the small target visibility (STV) method.

TRB's National Cooperative Highway Research Program (NCHRP) Report 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.

Context-sensitive solutions (CSS) reflect the need to consider highway projects as more than just transportation facilities. Depending on how highway projects are integrated into the community, they can have far-reaching impacts beyond their traffic or transportation function. CSS is a comprehensive process that brings stakeholders together in a positive, proactive environment to develop projects that not only meet transportation needs, but also improve or enhance the community. Achieving a flexible, context-sensitive design solution requires designers to fully understand the reasons behind the processes, design values, and design procedures that are used. This AASHTO Guide shows highway designers how to think flexibly, how to recognize the many choices and options they have, and how to arrive at the best solution for the particular situation or context. It also strives to emphasize that flexible design does not necessarily entail a fundamentally new design process, but that it can be integrated into the existing transportation culture. This publication represents a major step toward institutionalizing CSS into state transportation departments and other agencies charged with transportation project development.

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

A replacement to the publication entitled 'Highway design and operational practices related to highway safety', also known as 'The Yellow Book', and most recently published in 1974.

The face of the pedestrian safety crisis looks a lot like Ignacio Duarte-Rodriguez. The 77-year old grandfather was struck in a hit-and-run crash while trying to cross a high-speed, six-lane road without crosswalks near his son’s home in Phoenix, Arizona. He was one of the more than 6,000 people killed while walking in America in 2018. In the last ten years, there has been a 50 percent increase in pedestrian deaths. The tragedy of traffic violence has barely registered with the media and wider culture. Disproportionately the victims are like Duarte-Rodriguez—immigrants, the poor, and people of color. They have largely been blamed and forgotten. In Right of Way, journalist Angie Schmitt shows us that deaths like Duarte-Rodriguez’s are not unavoidable “accidents.” They don’t happen because of jaywalking or distracted walking. They are predictable, occurring in stark geographic patterns that tell a story about systemic inequality. These deaths are the forgotten faces of an increasingly urgent public-health crisis that we have the tools, but not the will, to solve. Schmitt examines the possible causes of the increase in pedestrian deaths as well as programs and movements that are beginning to respond to the epidemic. Her investigation unveils why pedestrians are dying—and she demands action. Right of Way is a call to reframe the problem, acknowledge the role of racism and classism in the public response to these deaths, and energize advocacy around road safety. Ultimately, Schmitt argues that we need improvements in infrastructure and changes to policy to save lives. Right of Way unveils a crisis that is rooted in both inequality and the undeterred reign of the automobile in our cities. It challenges us to imagine and demand safer and more equitable cities, where no one is expendable.
