Highway engineers, as designers, strive to meet the needs of highway users while maintaining the integrity of the environment. Unique combinations of design controls and constraints that are often conflicting call for unique design solutions. A Policy on Geometric Design of Highways and Streets provides guidance based on established practices that are supplemented by recent research. This document is also intended as a comprehensive reference manual to assist in administrative, planning, and educational efforts pertaining to design formulation

The Negro Motorist Green Book was a groundbreaking guide that provided African American travelers with crucial information on safe places to stay, eat, and visit during the era of segregation in the United States. This essential resource, originally published from 1936 to 1966, offered a lifeline to black motorists navigating a deeply divided nation, helping them avoid the dangers and indignities of racism on the road. More than just a travel guide, The Negro Motorist Green Book stands as a powerful symbol of resilience and resistance in the face of oppression, offering a poignant glimpse into the challenges and triumphs of the African American experience in the 20th century.

"Hungry? Check the Green Book. Tired? Check the Green Book. Sick? Check the Green Book." In the late 1930s when segregation was legal and Black Americans couldn't visit every establishment or travel everywhere they wanted to safely, a New Yorker named Victor Hugo Green decided to do something about it. Green wrote and published a guide that listed places where his fellow Black Americans could be safe in New York City. The guide sold like hot cakes! Soon customers started asking Green to make a guide to help them travel and vacation safely across the nation too. With the help of his mail carrier co-workers and the African American business community, Green's guide allowed millions of African Americans to travel safely and enjoy traveling across the nation. In the first picture book about the creation and distribution of The Green Book, author Keila Dawson and illustrator Alleanna Harris tell the story of the man behind it and how this travel guide opened the road for a safer, more equitable America.

The picture book inspiration for the Academy Award-winning film The Green Book Ruth was so excited to take a trip in her family's new car! In the early 1950s, few African Americans could afford to buy cars, so this would be an adventure. But she soon found out that Black travelers weren't treated very well in some towns. Many hotels and gas stations refused service to Black people. Daddy was upset about something called Jim Crow laws . . . Finally, a friendly attendant at a gas station showed Ruth's family The Green Book. It listed all of the places that would welcome Black travelers. With this guidebook—and the kindness of strangers—Ruth could finally make a safe journey from Chicago to her grandma's house in Alabama. Ruth's story is fiction, but The Green Book and its role in helping a generation of African American travelers avoid some of the indignities of Jim Crow are historical fact.

Bloomberg • Best Nonfiction Books of 2020: "[A] tour de force." The basis of a major PBS documentary by Ric Burns, this “excellent history” (The New Yorker) reveals how the automobile fundamentally changed African American life. Driving While Black demonstrates that the car—the ultimate symbol of independence and possibility—has always held particular importance for African Americans, allowing black families to evade the dangers presented by an entrenched racist society and to enjoy, in some measure, the freedom of the open road. Melding new archival research with her family’s story, Gretchen Sorin recovers a lost history, demonstrating how, when combined with black travel guides—including the famous Green Book—the automobile encouraged a new way of resisting oppression.

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.
