TRB's National Cooperative Highway Research Program (NCHRP) Report 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.

TRB' National Cooperative Highway Research Program (NCHRP) Report 674: Crossing Solutions at Roundabouts and Channelized Turn Lanes for Pedestrians with Vision Disabilities explores information related to establishing safe crossings at roundabouts and channelized turn lanes for pedestrians with vision disabilities. Appendices B through N to NCHRP Report 674 were published as NCHRP Web-Only Document 160.

"Portions of thirty diaries or journals of people who actually crossed Arizona are included to depict how Arizona was perceived from 1699 until 1863"--Jacket.

This handbook briefly describes how growth of railroads and highways resulted in a proliferation of grade crossings and then discusses the variety of methods developed to warn pedestrians and vehicles of approaching trains. It is aimed primarily at providing railroad, state and municipal personnel with information which can help in cooperative efforts to improve grade crossing safety and efficiency. The book describes conditions and requirements at crossing; facilitates understanding of the elements of crossing systems; provides a compendium of existing grade crossing technology; serves as a guideline to aid in implementing improvements to grade crossings; aids in understanding and applying new technology; and serves as a basic text for training programs.

Crossing Numbers of Graphs is the first book devoted to the crossing number, an increasingly popular object of study with surprising connections. The field has matured into a large body of work, which includes identifiable core results and techniques. The book presents a wide variety of ideas and techniques in topological graph theory, discrete geometry, and computer science. The first part of the text deals with traditional crossing number, crossing number values, crossing lemma, related parameters, computational complexity, and algorithms. The second part includes the rich history of alternative crossing numbers, the rectilinear crossing number, the pair crossing number, and the independent odd crossing number.It also includes applications of the crossing number outside topological graph theory. Aimed at graduate students and professionals in both mathematics and computer science The first book of its kind devoted to the topic Authored by a noted authority in crossing numbers
