Book Description
The Intersection Decision Support (IDS) system is designed to assist drivers on stop-controlled low-volume rural roads choosing gaps when confronted with busy multiple lane divided-highways, without affecting traffic on the high-volume road. The hope is, that by providing better gap guidance, fewer crashes (and fatalities) will occur. This research develops a framework for analyzing such a new, and presently under-specified technology, and illustrates that framework by comparing that with more conventional engineering approaches, as well as a "donothing" base case. The results show that the IDS System may be an effective tool to reduce crash rates at various intersections. More research is needed to address reliability and stability issues, and in determining how cost effective of a solution the IDS System is compared to other "traditional" alternatives.

Book Description
This project entailed the design, development, testing, and evaluation of intersection decision support (IDS) systems to address straight crossing path (SCP) intersection crashes. This type of intersection crash is responsible for more than 100,000 crashes and thousands of fatalities each year. In developing these IDS systems for both signalized and stop-controlled intersections, a top-down systems approach was used that determined the necessary system functions and evaluated the capability of different technologies to perform those functions. Human factors tests were also conducted that evaluated the effectiveness of warning algorithms and infrastructure-based driver-infrastructure interfaces in eliciting a stopping response from drivers about to be involved in an SCP intersection crash. Results indicated that further technological development is needed for the sensing and intersection state IDS functions. Furthermore, infrastructure-based warning interfaces tested were greatly outperformed by previously-tested in-vehicle warnings. Thus, future research on IDS systems should focus on their infrastructure-cooperative configuration, where the system supports an in-vehicle warning.

Book Description
The purpose of the Highway Safety Benefit-Cost Analysis (BCA) Guide is to assist transportation agencies in making consistent and sound investment decisions. The target audience includes transportation professionals such as traffic engineers, highway safety engineers, and planners conducting highway safety BCA for projects and programs. This Guide will help these users to quantify the costs, and direct and indirect safety-related benefits of project alternatives. Direct safety benefits include the expected change in crash frequency and severity. Indirect benefits include the operational and environmental benefits that result from a reduction in crashes (e.g., reduced delay, fuel use, and emissions). Readers will understand the methods, data requirements, and considerations associated with BCA. Examples demonstrate the application of the methods in various scenarios, including both site-specific and systemic projects with single or multiple countermeasures. Conducting consistent and reliable BCA will support decision making, optimize the return on investments, and increase the effectiveness of projects and programs.

Book Description
'This book is a superb textbook treatment of benefit–cost analysis. It is well designed for students in public policy, public administration, public health, social work, environmental affairs, law and business.' – John D. Graham, Indiana University, US 'Principles and Standards for Benefit–Cost Analysis is well worth reading. The volume reproduces some chapters previously published online in the Journal of Benefit–Cost Analysis alongside new material that has not yet appeared in print, and does so in a logical and appealing way. Even the several chapters with which I disagreed made me think hard about my own views. And thinking hard is a good thing!' – Paul R. Portney, University of Arizona, US Benefit–cost analysis informs which policies or programs most benefit society when implemented by governments and institutions around the world. This volume brings together leading researchers and practitioners to recommend strategies and standards to improve the consistency and credibility of such analyses, assisting analysts of all types in achieving a greater uniformity of practice. Although new analytical approaches are constantly being used and tested, this book supports the emergence of a professional culture adhering to a set of principles and standards that can be used to identify useful analytical processes and to discard less useful ones. Contributors to this volume come from a wide variety of backgrounds and include authors of leading textbooks, editors of journals, former government officials, and practitioners whose analyses have shaped decisions about education, the environment, security, income distribution, and other vital social and economic policies. Students and professors of public sector economics will find much of interest in this groundbreaking book. Practitioners working in government, non-profit organizations, and international institutions, including welfare economists, policy analysts, environmentalists, engineers, and others will also benefit from this volume's sophisticated and practical recommendations.

Book Description
This primer provides a foundation for understanding the role of economic analysis in highway decision making. It is oriented toward state and local officials who have responsibility for assuring that limited resources get targeted to their best uses and who must publicly account for their decisions. Economic analysis is presented as an integral component of a comprehensive infrastructure management methodology that takes a long-term view of infrastructure performance and cost. The primer encompasses a full range of economic issues, including economic fundamentals, life-cycle cost analysis, benefit-cost analysis, forecasting traffic for benefit calculations, risk analysis and economic impact analysis.

Book Description
This review of benefit-cost analysis as a tool for evaluating alternative courses of action describes the technique, discusses a number of benefit-cost studies, and indicates the difficulties inherent in this area of applied economics. * The author concentrates on the application of the technique to large scale transport problems, reviews the literature and indicates in his conclusions where the technique can be helpful and where there is little chance for its success.

Book Description
Fuguitt and Wilcox skillfully guide analysts, public sector managers, and students of decision-making through a full range of the essential steps to perform, interpret, and assess cost-benefit analysis. Their book shows how to grasp the principles of cost-benefit analysis and several related economic valuation methods, how to apply them in undertaking an objective analysis, and how to use the analysis as a decision-making tool across a wide range of fields and applications. An extensive knowledge of economic theory, calculus or advanced graphical analysis is not needed to understand the principles or techniques. Accessible to those who understand basic algebra and have a beginner's hold on statistics, the book also provides a bridge to the more advanced literature in economics and to other analyses used to perform sophisticated valuations. A unique, much-needed presentation of all that is required to gain an immediate, useful understanding of the topic. The authors explain basic economic concepts and show how they are relevant to understanding an analytical approach. They enumerate principles and detail such technical components as with and without analysis, discounting, decision criteria and uncertainty assessment. The book provides especially extensive coverage of the contingent valuation method along with market valuation, the travel cost and property value methods, human life valuation, and cost-effectiveness analysis. They explain empirical methods used to perform these valuation techniques and cover survey and regression analysis as well. Most importantly, Fuguitt and Wilcox treat the topic within its real-world context—as a decision-making tool to assess a particular policy's efficiency and to provide the decision maker with necessary information. Trade-offs between efficiency and other policy objectives are also addressed, as is the interdisciplinary setting within which cost-benefit analysis is interpreted, enabling readers to understand that policy advocates and adversaries bring their own values and competing interests to bear on any decision-making process.
