Nchrp Research Results Digest 351

The first and only comprehensive guide to best practices in winter road operations Winter maintenance operations are essential to ensure the safety, mobility, and productivity of transportation systems, especially in cold-weather climates, and responsible agencies are continually challenged to provide a high level of service in a fiscally and environmentally responsible manner. Sustainable Winter Road Operations bridges the knowledge gaps, providing the first up-to-date, authoritative, single-source overview and guide to best practices in winter road operations that considers the triple bottom line of sustainability. With contributions from experts in the field from around the world, this book takes a holistic approach to the subject. The authors address the many negative impacts on regional economies and the environment of poorly planned and inadequate winter road operations, and they make a strong case for the myriad benefits of environmentally sustainable concepts and practices. Best practice applications of materials, processes, equipment, and associated technologies and how they can improve the effectiveness and efficiency of winter operations, optimize materials usage, and minimize cost, corrosion, and environmental impacts are all covered in depth. Provides the first up-to-date, authoritative and comprehensive overview of best practices in sustainable winter road operations currently in use around the world Covers materials, processes, equipment, and associated technologies for sustainable winter road operations Brings together contributions by an international all-star team of experts with extensive experience in designing, implementing, and managing sustainable winter road operations Designed to bring professionals involved in transportation and highway maintenance and control up to speed with current best practice Sustainable Winter Road Operations is essential reading for maintenance professionals dealing with snow and ice control operations on highways, motorways and local roads. It is a valuable source of information and guidance for decision makers, researchers, and engineers in transportation engineering involved in transportation and highway maintenance. And it is an ideal textbook for advanced-level courses in transportation engineering.

"This digest summarizes key findings obtained in 2009 and 2010 from continuing NCHRP Project 9-26A, "Data Mining and Interlaboratory Studies to Prepare Precision Statements for AASHTO Standard Test Methods." Project 9-26A was conducted by the AASHTO Materials Reference Laboratory under the direction of the principal investigator, Haleh Azari. This digest is based on the contractor's task reports, which are available online as NCHRP Web-Only Documents 163 through 166."

The development of U.S. urban transportation policy over the past half-century illustrates the changing relationships among federal, state, and local governments. This comprehensive text examines the evolution of urban transportation planning from early developments in highway planning in the 1930s to today’s concerns over sustainable development, security, and pollution control. Highlighting major national events, the book examines the influence of legislation, regulations, conferences, federal programs, and advances in planning procedures and technology. The volume provides in-depth coverage of the most significant event in transportation planning, the Federal-Aid Highway Act of 1962, which created a federal mandate for a comprehensive urban transportation planning process, carried out cooperatively by states and local governments with federal funding. Claiming that urban transportation planning is more sophisticated, costly, and complex than its highway and transit planning predecessors, the book demonstrates how urban transportation planning evolved in response to changes in such factors as the environment, energy, development patterns, intergovernmental coordination, and federal transit programs. This updated, revised, and expanded edition features two new chapters on global climate change and managing under conditions of constrained resources, and covers the impact of the most recent legislation, 50 years after the Highway Act of 1962, emphasizing such timely issues as security, oil dependence, performance measurement, and public-private sector collaboration.

[This is] "a guidebook that addresses contemporary issues in workforce development, retention, and attraction, and public transportation image management. [It] is separated into modules that may be used independently or together [...]. Information across the modules is in the form of example successful programs, state-of-the-art initiatives, industry effective practices, and directions to implement and measure those practices. The results of this research may be used by human resource professionals and transportation policy makers in implementing more effective human resource business-planning processes"--Foreword.
