Book Description
The placement of guide signs and the display of dynamic massage signs greatly affect drivers' understanding of the network and therefore their route choices. Most existing dynamic traffic assignment models assume that drivers heading to a Major Traffic Generator (MTG) have sufficient knowledge of roadway networks. In this report, the concept of recognition level is defined to categorize drivers based on their unfamiliarity of the network and of the alternative routes between origins and destinations. Each catalog is assigned a specific utility function that is dependent on travel time, length of route and recognition parameters. Drivers' route choice behavior is determined by these specific utility functions. A sample network is first employed to test the feasibility of the proposed model, and the result complies with the specified travel patterns. After that, a real network near Downtown Houston is used to further test the proposed model. An experiment is conducted based on the information collected from an on-site survey and the on-line real-time traffic map from Houston TranStar. In order to validate the necessity of the proposed model, a control experiment is carried out with all parameters being set in the same way as the designed experiment except that drivers are assumed to be fully familiar with the network layout and alternative routes. Test results show that the proposed model can fit the real case very well. The developed algorithm and the assessment procedure results are not only awfully imperative in trailblazing guide signing for MTGs, but also indispensable in both the modern Route Guidance System (RGS) and the Advanced Traveler Information System (ATIS), which are important components of the Intelligent Transportation System (ITS).

Book Description
Except in a few instances, since World War II no American soldier or sailor has been attacked by enemy air power. Conversely, no enemy soldier orsailor has acted in combat without being attacked or at least threatened by American air power. Aviators have brought the air weapon to bear against enemies while denying them the same prerogative. This is the legacy of the U.S. AirForce, purchased at great cost in both human and material resources.More often than not, aerial pioneers had to fight technological ignorance, bureaucratic opposition, public apathy, and disagreement over purpose.Every step in the evolution of air power led into new and untrodden territory, driven by humanitarian impulses; by the search for higher, faster, and farther flight; or by the conviction that the air way was the best way. Warriors have always coveted the high ground. If technology permitted them to reach it, men, women andan air force held and exploited it-from Thomas Selfridge, first among so many who gave that "last full measure of devotion"; to Women's Airforce Service Pilot Ann Baumgartner, who broke social barriers to become the first Americanwoman to pilot a jet; to Benjamin Davis, who broke racial barriers to become the first African American to command a flying group; to Chuck Yeager, a one-time non-commissioned flight officer who was the first to exceed the speed of sound; to John Levitow, who earned the Medal of Honor by throwing himself over a live flare to save his gunship crew; to John Warden, who began a revolution in air power thought and strategy that was put to spectacular use in the Gulf War.Industrialization has brought total war and air power has brought the means to overfly an enemy's defenses and attack its sources of power directly. Americans have perceived air power from the start as a more efficient means of waging war and as a symbol of the nation's commitment to technology to master challenges, minimize casualties, and defeat adversaries.

Book Description
A master of the personal essay candidly explores love, death, and the counterfeit rituals of American life in this "brave, funny compendium" (Slate) Nearly fifteen years after her debut collection, My Misspent Youth, captured the ambitions and anxieties of a generation, Meghan Daum returns to the personal essay with The Unspeakable, a powerful collection of ten new works. Where her previous collection explores what it is to be a struggling twenty-something urban dweller with an overdrawn bank account and oversized ambition, The Unspeakable contends with parental death, the decision not to have children, and more-a new set of challenges tackled by a writer at her best, investigated in the same uncompromising voice that made Daum one of the most engaging thinkers writing today. In The Unspeakable, Daum pushes back against the false sentimentality and shrink-wrapped platitudes that surround so much of the contemporary American experience. But Daum also operates in a comic register. With perfect precision, she reveals the absurdities of the New Age search for the "Best Possible Experience," champions the merits of cream-of-mushroom-soup casserole, and gleefully recounts a quintessential "only-in-L.A." story of playing charades at a famous person's home. Combining the piercing insight of Joan Didion with humor reminiscent of Nora Ephron's, Daum dissects our culture's most dangerous illusions while retaining her own joy and compassion. Through it all, she dramatizes the search for an authentic self in a world where achieving an identity is never simple and never complete.

Book Description
A New York Times Book Review Editors' Choice | Winner of the New Deal Book Award An immersive account of the New Deal project that created state-by-state guidebooks to America, in the midst of the Great Depression—and employed some of the biggest names in American letters The plan was as idealistic as it was audacious—and utterly unprecedented. Take thousands of hard-up writers and put them to work charting a country on the brink of social and economic collapse, with the aim of producing a series of guidebooks to the then forty-eight states—along with hundreds of other publications dedicated to cities, regions, and towns—while also gathering reams of folklore, narratives of formerly enslaved people, and even recipes, all of varying quality, each revealing distinct sensibilities. All this was the singular purview of the Federal Writers’ Project, a division of the Works Progress Administration founded in 1935 to employ jobless writers, from once-bestselling novelists and acclaimed poets to the more dubiously qualified. The FWP took up the lofty goal of rediscovering America in words and soon found itself embroiled in the day’s most heated arguments regarding radical politics, racial inclusion, and the purpose of writing—forcing it to reckon with the promises and failures of both the New Deal and the American experiment itself. Scott Borchert’s Republic of Detours tells the story of this raucous and remarkable undertaking by delving into the experiences of key figures and tracing the FWP from its optimistic early days to its dismemberment by the House Committee on Un-American Activities. We observe notable writers at their day jobs, including Nelson Algren, broke and smarting from the failure of his first novel; Zora Neale Hurston, the most widely published Black woman in the country; and Richard Wright, who arrived in the FWP’s chaotic New York City office on an upward career trajectory courtesy of the WPA. Meanwhile, Ralph Ellison, Studs Terkel, John Cheever, and other future literary stars found encouragement and security on the FWP payroll. By way of these and other stories, Borchert illuminates an essentially noble enterprise that sought to create a broad and inclusive self-portrait of America at a time when the nation’s very identity and future were thrown into question. As the United States enters a new era of economic distress, political strife, and culture-industry turmoil, this book’s lessons are urgent and strong.
