The National Road is a comprehensive history of the first federally financed interstate highway, an approximately 600-mile span that joined Maryland, Pennsylvania, West Virginia, Ohio, Indiana, and Illinois in the nineteenth century. This book covers the road's contribution to the cultural, economic, and administrative history of the United States, its decline during the second half of the nineteenth century, and its revival in the twentieth century in the form of U.S. Route 40. The story of the National Road embraces an account of its building, its constitutional significance, the unique culture that it represented, the movements and trends that transpired across its route, and the symbolic value that it held, and continues to hold, for the American people. Beyond its status as an American heritage symbol, it serves as a forceful reminder that the United States must continue to pursue the goal of sustainable national investment that began with the National Road and comparable projects during the early republic.

This four-volume encyclopedia chronicles the historical roots of the United States' current military dominance, documenting its growth from continental expansionism to hemispheric hegemony to global empire. This groundbreaking four-volume encyclopedia offers sweeping coverage of a subject central to American history and of urgent importance today as the nation wrestles with a global imperial posture and the long-term viability of the largest military establishment in human history. The work features more than 650 entries encompassing the full scope of American expansionism and imperialism from the colonial era through the 21st-century "War on Terror." Readers will learn about U.S.-Native American conflicts; 19th-century land laws; early forays overseas, for example, the opening of Japan; and America's imperial conflicts in Cuba and the Philippines. U.S. interests in Latin America are explored, as are the often-forgotten ambitions that lay behind the nation's involvement in the World Wars. The work also offers extensive coverage of the Cold War and today's ongoing conflicts in Iraq, Afghanistan, Africa, and the Middle East as they relate to U.S. national interests. Notable individuals, including American statesmen, military commanders, influential public figures, and anti-imperialists are covered as well. The inclusion of cultural elements of American expansionism and imperialism—for example, Hollywood films and protest music—helps distinguish this set from other more limited works.

Since 1950, the Highway Capacity Manual has been a standard used in the planning, design, analysis, and operation of virtually any highway traffic facility in the United States. It has also been widely used around the globe and has inspired the development of similar manuals in other countries. This book is Volume II of a series on the conceptual and research origins of the methodologies found in the Highway Capacity Manual. It focuses on the most complex points in a traffic system: signalized and unsignalized intersections, and the concepts and methodologies developed over the years to model their operations. It also includes an overview of the fundamental concepts of capacity and level of service, particularly as applied to intersections. The historical roots of the manual and its contents are important to understanding current methodologies, and improving them in the future. As such, this book is a valuable resource for current and future users of the Highway Capacity Manual, as well as researchers and developers involved in advancing the state-of-the-art in the field.

From the award-winning author of American Canopy, a dazzling account of the world’s longest road, the Pan-American Highway, and the epic quest to link North and South America, a dramatic story of commerce, technology, politics, and the divergent fates of the Americas in the nineteenth and twentieth centuries. The Pan-American Highway, monument to a century’s worth of diplomacy and investment, education and engineering, scandal and sweat, is the longest road in the world, passable everywhere save the mythic Darien Gap that straddles Panama and Colombia. The highway’s history, however, has long remained a mystery, a story scattered among government archives, private papers, and fading memories. In contrast to the Panama Canal and its vast literature, the Pan-American Highway—the United States’ other great twentieth-century hemispheric infrastructure project—has become an orphan of the past, effectively erased from the story of the “American Century.” The Longest Line on the Map uncovers this incredible tale for the first time and weaves it into a tapestry that fascinates, informs, and delights. Rutkow’s narrative forces the reader to take seriously the question: Why couldn’t the Americas have become a single region that “is” and not two near irreconcilable halves that “are”? Whether you’re fascinated by the history of the Americas, or you’ve dreamed of driving around the globe, or you simply love world records and the stories behind them, The Longest Line on the Map is a riveting narrative, a lost epic of hemispheric scale.

Since 1950, the Highway Capacity Manual has been a standard used in the planning, design, analysis, and operation of virtually any highway traffic facility in the United States. It has also been widely used abroad, and has spurred the development of similar manuals in other countries. The twin concepts of capacity and level of service have been developed in the manual, and methodologies have been presented that allow highway traffic facilities to be designed on a common basis, and allow for the analysis of operational quality under various traffic demand scenarios. The manual also addresses related pedestrian, bicycle, and transit issues. This book details the fundamental development of the concepts of capacity and level of service, and of the specific methodologies developed to describe them over a wide range of facility types. The book is comprised of two volumes. Volume 1 (this book) focuses on the development of basic principles, and their application to uninterrupted flow facilities: freeways, multilane highways, and two-lane highways. Weaving, merging, and diverging segments on freeways and multilane highways are also discussed in detail. Volume 2 focuses on interrupted flow facilities: signalized and unsignalized intersections, urban streets and arterials. It is intended to help users of the manual understand how concepts, approaches, and specific methodologies were developed, and to understand the underlying principles that each embodies. It is also intended to act as a basic reference for current and future researchers who will continue to develop new and improved capacity analysis methodologies for many years to come.

In 1750 the Appalachian Mountains were a formidable barrier between the British colonies in the east and French territory in the west, passable only on foot or horseback. It took more than a century to break the mountain barrier and open the west to settlement. In 1751 a private Virginia company pioneered a road from Maryland to Ohio, challenging the French and Indians for the Ohio country. Several wars stalled the road, which did not start in earnest until after Ohio became a state in 1803. The stone-paved Cumberland Road--from Cumberland, Maryland, to Wheeling, Virginia--was complete by 1818 and over the next 30 years was traversed by Conestoga wagons and stagecoaches. The Baltimore and Ohio Railroad--the first general purpose railroad in the world--started in Baltimore in the 1820s and reached Wheeling by 1852, uniting east and west.
