As an important industry, transportation costs account for a considerable percentage of the gross national product of countries. It is therefore key to have at the disposal of those concerned with transportation activities, a bibliographical literature on costs and costing. The bibliography lists books, papers, technical reports, journal articles, and information rarely found in books and dissertations.

The interest in the mathematical modeling of transportation systems stems from the need to predict how people might make use of new or improved transport infrastruc ture in order to evaluate the benefit of the required investments. To this end it is necessary to build models of the demand for transportation and models that de termine the way in which people who travel use the transportation network. If such models may be constructed and their validity reasonably assured, then the predic tion of the traffic flows on future and present transportation links may be carried out by simulating future situations and then evaluating the potential benefits of alternative improvement projects. In the attempts that were made to construct mathematical models of transportation networks, the notion of equilibrium plays a central role. Suppose that the demand for transportation, that is, the number of trips that occur between the - rious origins and destinations is known. Then it is necessary to determine how these trips are attracted to the alternative routes available between origins and destinations. Knight (1924), gave a simple and intuitively clear description of the behaviour of road traffic under conditions of congestion.

In 1920, state highway engineers, federal officials, and experts from academia were among a small group convened by the National Academy of Sciences to confront the problems of the highway. The public was entrusting them with billions of dollars for good roads, and World War I had proved the feasibility of moving freight long distances by truck. But even new highways were crumbling. They turned to research for solutions. The founders of the Transportation Research Board (TRB) and the generations that followed took on problems such as safety, social equity, and environmental issues. They embraced "total transportation," adapting their highway research model to urban transportation and then applying it to rail, marine, and aviation modes. Today TRB convenes thousands of researchers, practitioners, and administrators every year to advise the government, solve practical problems, foster innovation, and stimulate new research. In The Transportation Research Board, 1920â€"2020: Everyone Interested Is Invited, Sarah Jo Peterson tells the story of how people and institutions created and have continued to shape TRB. In a compelling narrative accompanied by more than 150 images exploring the history of transportation and research, she argues that TRB can be best understood as an infrastructureâ€"one that people purposely designed and devotedly maintained. Despite TRB's institutional complexity, its unique mission, the vast collection of acronyms in its orbit, and the significant changes to the organization in its first 100 years, Dr. Peterson provides a view from 30,000 feet, deftly describing the social, political, and economic context in which transportation (and TRB) functioned. At the same time, she attends to details of the key events, individuals, and human motivations that shaped TRB's evolution. The author's skills as a historian, her experience in the transportation field, and her manifest ability to tell a good story have produced a book that transportation professionals of all stripesâ€"and, for that matter, anyone interested in the history of transportation in the United Statesâ€"should find both engaging and informative and an essential addition to their library.
