This synthesis will be of interest to state department of transportation (DOT) administrators and mid- to upper-level managers; researchers; cost estimators; bridge and general management system engineers; and bridge design, construction, inspection and maintenance engineers; as well as to private industry professionals involved in developing bridge management system (BMS) software and collecting and analyzing BMS cost data. The state of the practice for collecting and managing cost data for BMS is described based on data obtained from a review of the literature and a survey of the state DOTs. This report describes BMS cost data for work done by contract and in-house forces for state and local governments. It includes project-level cost estimation as well as the collection and management of data for network- level cost models. The various cost estimate methods for replacement; maintenance, repair and rehabilitation; and emergency work are analyzed as are the special requirements of user costs and other special economic data.

This synthesis will be of interest to state department of transportation bridge design and structural engineers, bridge consultants, and others involved in applied and research methods for increasing the live load capacity of existing highway bridges. The synthesis describes the current state of the practice for the various methods used to increase the live load capacity of existing highway bridges. This is done predominantly for bridges in the short- to medium-span range. Information on the more common bridge material types is presented. There is an emphasis on superstructure rather than substructure strengthening.

"Technologies for Improving Safety Data explores new technologies for the acquisition, processing, and overall management of crash, roadway inventory, and traffic operations data. The report examines the current state-of-the-practice and state-of-the-art use of technologies for efficient and effective collection and maintenance of data for highway safety analysis." -- publisher's website.

The Intermodal Surface Transportation Efficiency Act of 1991 required states to develop and implement 6 systems for managing highway pavement, bridges, highway safety, traffic congestion, public transportation facilities and equipment, and intermodal transportation facilities and systems. In 1995, the National Highway System Designation Act made the systems optional. This report identifies: the status of the states' development and implementation of the transportation management systems; how the states expect to use the systems; and the factors that have facilitated or hindered the development and implementation of the systems.

The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) required states to develop and implement six systems for managing highway pavement, bridges, highway safety, traffic congestion, public transportation facilities and equipment, and intermodal transportation facilities and systems. In 1995, the National Highway System Designation Act of 1995 - often called the NHS Act - made the systems optional, except the congestion management system in certain areas, and prohibited the U.S. Department of Transportation (DOT) from withholding funds from states that elected not to implement any system. In addition, the NHS Act required the General Accounting Office (GAO) to examine issues concerning the states' implementation of the management systems. GAO agreed to identify (1) the status of the states' development and implementation of the systems, (2) how the states expect to use the systems, and (3) the factors that have facilitated or hindered the development and implementation of the systems.

TRB's National Cooperative Highway Research Program (NCHRP) Report 668: Framework for a National Database System for Maintenance Actions on Highway Bridges explores a potential framework that provides a uniform format for collecting, reporting, and storing information on bridge maintenance actions for inclusion in a national bridge maintenance database. Appendixes A through E to NCHRP Report 668 provide detailed information on the different aspects of the research. Appendix A: Information on Bridge Maintenance Programs; Appendix B: National Bridge Maintenance Database Tables; Appendix C: List of Element Level Costs of Maintenance Actions; Appendix D: Examples of National Bridge Maintenance Database Uses; Appendix E: Other National Bridge Maintenance Database Tables--

NCHRP synthesis 371 explores the state of the practice for managing transportation infrastructure assets other than pavements and bridges, and documents gaps in knowledge and areas in need of potential further study.

This study gathers information on current practices that senior managers at transportation agencies use to make network-level decisions on resource allocations for their bridge programs. In particular, the study explores how agency bridge management systems are employed in this process. Information was gathered through a review of literature on U.S. and international bridge management, a survey of U.S. and Canadian transportation agencies, and 15 in-depth interviews with state DOT executive and bridge managers.

In this new fifth edition, there is a strong focus on the increasing concern over infrastructure resilience from the threat of serious storms, human activity, and population growth. The new edition also looks technologies that urban transportation planners are increasingly focused on, such as vehicle to vehicle communications and driver-less cars, which have the potential to radically improve transportation. This book also investigates the effects of transportation on the health of travelers and the general public, and the ways in which these concerns have become additional factors in the transportation and infrastructure planning and policy process. 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 new edition includes analyses of the growing threats to infrastructure, new projects in infrastructure resilience, the promise of new technologies to improve urban transportation, and the recent shifts in U.S. transportation policy. This book will be of interest to researchers and practitioners in transportation legislation and policy, eco-justice, and regional and urban planning.
