Download or read book Tradeoffs in Transportation Repair and Rehabilitation Decision making written by Alexis J. Withers and published by . This book was released on 2021 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over time, infrastructure elements such as roads, highways, bridges, and even transit stations degrade, surpass their designed life expectancy, and require repair or rehabilitation to maintain functionality and deliver the utmost or acceptable levels of performance, particularly safety and efficiency. Deteriorating infrastructure creates an increase in construction and although construction creates various traffic impacts, it is necessary to return the deteriorating infrastructure to functional operation. This can mean enhancing a given highway to meet (or exceed) the daily or annual traffic demand or completing a project in a condensed amount of time due to the negative impact on users. This exploratory case study analyzes the multi-modal and multi-attribute tradeoffs in the case of the 2014 repair of the I-495 bridge across the Christina River in Wilmington following its emergency closure. The case study examines user shifts in travel patterns, agency plans to minimize disruption, and innovative construction methods to accelerate the restoration of the bridge to service. From the data presented in this case study, it was determined that the I-495 bridge closure increased volume and congestion on nearby roadways which resulted in temporary construction measures to be put into place. The project closure duration of just 59 days also created an increase in both bus and rail ridership. Overall, the I-495 emergency bridge closure was rare and unique project and is being used as a reference for decisions of future construction projects in the state.

Book excerpt: Transportation Decision Making A GUIDE TO EFFECTIVE DECISION MAKING WRITTEN JUST FOR TRANSPORTATION PROFESSIONALS This pioneering text provides a holistic approach to decision making in transportation project development and programming, which can help transportation professionals to optimize their investment choices. The authors present a proven set of methodologies for evaluating transportation projects that ensures that all costs and impacts are taken into consideration. The text’s logical organization gets readers started with a solid foundation in basic principles and then progressively builds on that foundation. Topics covered include: Developing performance measures for evaluation, estimating travel demand, and costing transportation projects Performing an economic efficiency evaluation that accounts for such factors as travel time, safety, and vehicle operating costs Evaluating a project’s impact on economic development and land use as well as its impact on society and culture Assessing a project’s environmental impact, including air quality, noise, ecology, water resources, and aesthetics Evaluating alternative projects on the basis of multiple performance criteria Programming transportation investments so that resources can be optimally allocated to meet facility-specific and system-wide goals Each chapter begins with basic definitions and concepts followed by a methodology for impact assessment. Relevant legislation is discussed and available software for performing evaluations is presented. At the end of each chapter, readers are provided resources for detailed investigation of particular topics. These include Internet sites and publications of international and domestic agencies and research institutions. The authors also provide a companion Web site that offers updates, data for analysis, and case histories of project evaluation and decision making. Given that billions of dollars are spent each year on transportation systems in the United States alone, and that there is a need for thorough and rational evaluation and decision making for cost-effective system preservation and improvement, this text should be on the desks of all transportation planners, engineers, and educators. With exercises in every chapter, this text is an ideal coursebook for the subject of transportation systems analysis and evaluation.

Download or read book Encyclopedia of Transportation written by Mark Garrett and published by SAGE Publications. This book was released on 2014-08-13 with total page 2000 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viewing transportation through the lens of current social, economic, and policy aspects, this four-volume reference work explores the topic of transportation across multiple disciplines within the social sciences and related areas, including geography, public policy, business, and economics. The book’s articles, all written by experts in the field, seek to answer such questions as: What has been the legacy, not just economically but politically and socially as well, of President Eisenhower’s modern interstate highway system in America? With that system and the infrastructure that supports it now in a state of decline and decay, what’s the best path for the future at a time of enormous fiscal constraints? Should California politicians plunge ahead with plans for a high-speed rail that every expert says—despite the allure—will go largely unused and will never pay back the massive investment while at this very moment potholes go unfilled all across the state? What path is best for emerging countries to keep pace with dramatic economic growth for their part? What are the social and financial costs of gridlock in our cities? Features: Approximately 675 signed articles authored by prominent scholars are arranged in A-to-Z fashion and conclude with Further Readings and cross references. A Chronology helps readers put individual events into historical context; a Reader’s Guide organizes entries by broad topical or thematic areas; a detailed index helps users quickly locate entries of most immediate interest; and a Resource Guide provides a list of journals, books, and associations and their websites. While articles were written to avoid jargon as much as possible, a Glossary provides quick definitions of technical terms. To ensure full, well-rounded coverage of the field, the General Editor with expertise in urban planning, public policy, and the environment worked alongside a Consulting Editor with a background in Civil Engineering. The index, Reader’s Guide, and cross references combine for thorough search-and-browse capabilities in the electronic edition. Available in both print and electronic formats, Encyclopedia of Transportation is an ideal reference for libraries and those who want to explore the issues that surround transportation in the United States and around the world.

Download or read book Optimizing Highway Reconstruction and Rehabilitation Projects written by Wallied Orabi and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The nation0́9s transportation networks including its roads, highways and bridges are aging and deteriorating at an increasing and rapid rate. The vulnerability of these aging networks of roads and bridges is exacerbated when they are subjected to natural disasters such as earthquakes and hurricanes which often cause severe disruption of the level of service provided by these transportation networks. Significant financial and construction resources are needed to complete the highway reconstruction and rehabilitation projects required to repair these aging and damaged transportation networks and bringing them to acceptable levels. The lack of sufficient resources to complete these highway construction projects concurrently requires effective and efficient utilization of these limited financial and construction resources in order to satisfy multiple and often conflicting objectives. Accordingly, there is a pressing need for new decision support models that are capable of: (1) analyzing the impact of reconstruction/rehabilitation efforts on the performance of transportation networks; (2) optimizing post-disaster reconstruction efforts of damaged transportation networks in order to simultaneously minimize reconstruction costs and network service disruption; and (3) optimizing highway rehabilitation of deficient transportation networks in order identify optimal program(s) that maximize net societal benefits while minimizing the level of service disruption experienced by travelers during the construction efforts. First, a highway service disruption model is developed to support measuring and evaluating the expected disruption in the level of service provided by aging and damaged transportation networks during highway reconstruction and rehabilitation projects. The model considers the impact of construction projects and their dynamic nature on the functional performance of aging and damaged transportation networks during reconstruction and rehabilitation efforts. The capabilities of the developed model in assessing the service disruption in aging and damaged transportation networks, include: (1) considering the dynamic nature of construction operations and activities and identifying their expected impact on the functional performance of aging and damaged transportation networks during reconstruction and rehabilitation efforts; (2) accounting for the rationality of travelers in choosing which route/detour to use to reach their destinations; and (3) evaluating the overall loss/savings in network travel time of the aging and damaged transportation networks during highway reconstruction and rehabilitation efforts. These new and unique capabilities of the developed model should prove useful to decision makers and planners in departments of transportation (DOTs) and should contribute to planning and optimizing highway reconstruction and rehabilitation efforts. Second, resource utilization model and multi-objective optimization models are developed to enable an efficient and effective reconstruction process for damaged transportation networks in the aftermath of natural disasters. The developed models provide a number of new and unique capabilities in generating optimal tradeoffs between network service disruption and reconstruction cost. These capabilities include: (1) considering the impact of the limited availability of resources on scheduling the reconstruction efforts for damaged transportation networks; (2) evaluating the service disruption in the damaged transportation network during the reconstruction efforts; and (3) optimizing the utilization of reconstruction resources to minimize the network service disruption of damaged transportation networks while keeping the reconstruction costs to a minimum. These new and unique capabilities of the developed models should prove useful to decision makers and planners in emergency management agencies and should contribute to enhancing the planning of reconstruction efforts for damaged transportation networks after natural disasters. Third, a highway rehabilitation planning and optimization model is developed to enable efficient and effective rehabilitation of aging transportation networks. This model incorporates four new modules that provide new capabilities in generating optimal tradeoffs between maximizing net rehabilitation benefits and minimizing network service disruption. These capabilities are demonstrated in the ability of the developed rehabilitation planning and optimization model to consider a number of practical highway rehabilitation requirements, including: (1) considering the impact of the limited availability of funding on planning rehabilitation efforts for aging transportation networks; (2) evaluating the expected service disruption and road user savings during and after completion of rehabilitation efforts; (3) estimating the expected net benefits of rehabilitation programs; and (4) optimizing the allocation of financial resources to maximize net rehabilitation benefits and minimize network service disruption. These new and unique capabilities of the research developments presents in this chapter should prove useful to decision makers and planners in departments of transportation (DOTs) and should contribute to enhancing the planning of rehabilitation efforts for aging transportation networks. The main research developments of this study are expected to contribute to the advancement of current practices in highway construction planning and optimization and can lead to: (1) accelerating the completion of highway reconstruction and rehabilitation projects and minimizing the service disruption experienced by travelers during the construction work; (2) optimizing the allocation of limited budgets and financial resources to competing highway projects; and (3) improving the utilization efficiency of construction resources in highway projects and therefore increasing their productivity.

Available in PDF, EPUB and Kindle. Book excerpt: In the current context of the electronic governance of society, both administrations and citizens are demanding the greater participation of all the actors involved in the decision-making process relative to the governance of society. This book presents collective works published in the recent Special Issue (SI) entitled “Optimization for Decision Making II”. These works give an appropriate response to the new challenges raised, the decision-making process can be done by applying different methods and tools, as well as using different objectives. In real-life problems, the formulation of decision-making problems and the application of optimization techniques to support decisions are particularly complex and a wide range of optimization techniques and methodologies are used to minimize risks, improve quality in making decisions or, in general, to solve problems. In addition, a sensitivity or robustness analysis should be done to validate/analyze the influence of uncertainty regarding decision-making. This book brings together a collection of inter-/multi-disciplinary works applied to the optimization of decision making in a coherent manner.
