Driving is a fact of life. We are all spending more and more time on the road, and traffic is an issue we face everyday. This book will make you think about it in a whole new light. We have always had a passion for cars and driving. Now Traffic offers us an exceptionally rich understanding of that passion. Vanderbilt explains why traffic jams form, outlines the unintended consequences of our attempts to engineer safety and even identifies the most common mistakes drivers make in parking lots. Based on exhaustive research and interviews with driving experts and traffic officials around the globe, Traffic gets under the hood of the quotidian activity of driving to uncover the surprisingly complex web of physical, psychological and technical factors that explain how traffic works.
Experts address some of the main issues and uncertainties associated with the design and deployment of Automated Highway Systems (AHS). They discuss new AHS concepts, technology, and benefits, as well as institutional, environmental, and social issues - concerns that will affect dramatically the operation of the current highway system from both the vehicle and infrastructure points of view.
The increasing power of computer technologies, the evolution of software en- neering and the advent of the intelligent transport systems has prompted traf c simulation to become one of the most used approaches for traf c analysis in s- port of the design and evaluation of traf c systems. The ability of traf c simulation to emulate the time variability of traf c phenomena makes it a unique tool for capturing the complexity of traf c systems. In recent years, traf c simulation – and namely microscopic traf c simulation – has moved from the academic to the professional world. A wide variety of traf- c simulation software is currently available on the market and it is utilized by thousands of users, consultants, researchers and public agencies. Microscopic traf c simulation based on the emulation of traf c ows from the dynamics of individual vehicles is becoming one the most attractive approaches. However, traf c simulation still lacks a uni ed treatment. Dozens of papers on theory and applications are published in scienti c journals every year. A search of simulation-related papers and workshops through the proceedings of the last annual TRB meetings would support this assertion, as would a review of the minutes from speci cally dedicated meetings such as the International Symposiums on Traf c Simulation (Yokohama, 2002; Lausanne, 2006; Brisbane, 2008) or the International Workshops on Traf c Modeling and Simulation (Tucson, 2001; Barcelona, 2003; Sedona, 2005; Graz 2008). Yet, the only comprehensive treatment of the subject to be found so far is in the user’s manuals of various software products.

Frederick Douglass called the martyred president "emphatically the black man's president” as well as “the first who rose above the prejudice of his times and country.” This narrative history of Lincoln’s personal interchange with Black people over the course his career reveals a side of the sixteenth president that, until now, has not been fully explored or understood. In a little-noted eulogy delivered shortly after Lincoln's assassination, Frederick Douglass called the martyred president "emphatically the black man's president," the "first to show any respect for their rights as men.” To justify that description, Douglass pointed not just to Lincoln's official acts and utterances, like the Emancipation Proclamation or the Second Inaugural Address, but also to the president’s own personal experiences with Black people. Referring to one of his White House visits, Douglass said: "In daring to invite a Negro to an audience at the White House, Mr. Lincoln was saying to the country: I am President of the black people as well as the white, and I mean to respect their rights and feelings as men and as citizens.” But Lincoln’s description as “emphatically the black man’s president” rests on more than his relationship with Douglass or on his official words and deeds. Lincoln interacted with many other African Americans during his presidency His unfailing cordiality to them, his willingness to meet with them in the White House, to honor their requests, to invite them to consult on public policy, to treat them with respect whether they were kitchen servants or leaders of the Black community, to invite them to attend receptions, to sing and pray with them in their neighborhoods—all those manifestations of an egalitarian spirit fully justified the tributes paid to him by Frederick Douglass and other African Americans like Sojourner Truth, who said: "I never was treated by any one with more kindness and cordiality than were shown to me by that great and good man, Abraham Lincoln.” Historian David S. Reynolds observed recently that only by examining Lincoln’s “personal interchange with Black people do we see the complete falsity of the charges of innate racism that some have leveled against him over the years.”
