This book was released on 2004 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintaining the infrastructure of roads, highways, and bridges is paramount to ensuring that these assets will remain safe and reliable in the future. If maintenance costs remain the same or continue to escalate, and additional funding is not made available, the highway agency may need to reduce new construction or cut back on maintenance, or both. There is a close relationship between the cost of optimally scheduled preventive maintenance versus the cost of emergency maintenance or replacement. The study develops a systemic risk-based asset management methodology to manage the maintenance of highway infrastructure systems. The decisionmaking methodology is used to harmonize and coordinate the actions of the different units and levels in a hierarchical organization. The systemic methodology enables the filtering and assessment of assets for maintenance while addressing the potential for extreme events. The methodology balances the costs, benefits, and risks of maintenance and inspection policies as applied to various types of assets. Three objective functions are used in evaluating options and strategies: minimizing short-term cost, minimizing long-term cost, and maximizing the remaining service life of highway assets. A constraint function harmonizes the remaining service life across assets to eliminate infeasible options. The methodology is generally applicable to the asset management of large-scale dynamic systems that exhibit similar characteristics as highway systems.

Download or read book Risk Assessment and Management of Critical Highway Infrastructure written by and published by . This book was released on 2004 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study expands upon the scope of a previous contract study for the Virginia Transportation Research Council (VTRC) concluded in March 2002. The objective is to develop methodologies for risk analysis of critical highway infrastructure at two levels: (1) system level and (2) asset level. The system-level analysis conducts risk assessment from a statewide perspective. The goal is to evaluate and prioritize infrastructure from a considerable inventory of assets. The definition of critical infrastructure offered by Presidential Decision Directive (PDD) 63 is used to determine the set of attributes that help differentiate critical from non-critical infrastructure. These attributes correspond to national, regional, and local impact of a structure's damage or complete loss. In addition, the levels of impact are utilized in prioritization: infrastructure that has potential national and regional impact is considered more important than infrastructure with local impact. Further prioritization is conducted based on the asset's need for risk management actions. The asset's current state or condition, in terms of resilience, robustness, redundancy, and security against willful threat is used to evaluate the need for management actions. A set of criteria and corresponding metrics is identified, and supporting data are gathered using information from the FHWA National Bridge Inventory and other sources. Once the most critical infrastructure is prioritized, an in-depth risk assessment of particular assets is performed to determine specific risks and vulnerabilities. Eight case studies on selected VDOT sites are conducted. The details of these case studies are not presented in this report. Instead, general findings are presented that can serve as a guideline for policy implementation to other similar assets. Since a small number of case studies are performed by the project team, another important goal of this study is for effective knowledge transfer of the methodology to VDOT in order to facilitate risk assessment of other critical infrastructure. For this purpose, a prototype computer tool is developed, which is designed to guide facility managers in risk assessment and management. The case studies and documentation of the computer tool are provided in supplemental documents available by request from the authors.

Available in PDF, EPUB and Kindle. Book excerpt: Infrastructure protection typifies a problem of risk assessment and management in a large-scale system. This study offers a methodological framework to identify, prioritize, assess, and manage risks. It includes the following major considerations: (1) a holistic approach to risk identification; (2) prioritization of a large number of risks or risk scenarios; (3) structured solicitation and effective integration of expert judgment into qualitative and quantitative analyses to supplement limited data availability; (4) extreme and catastrophic event analysis; and (5) use of multiobjective framework to evaluate management options (i.e., analyzing trade-offs among noncommensurate, conflicting objectives such as risk and cost). The methodology was illustrated using five case studies of selected transportation infrastructures in the Commonwealth of Virginia.

Download or read book Asset Management Implementation Plan and Tiered System Process written by Michael J. Markow and published by . This book was released on 2001 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study has developed a five-year transportation asset management plan for the Colorado Department of Transportation (CDOT). This study has also developed a proposed tiering structure of the state highway system to support asset management. Asset management represents a strategic approach to managing transportation infrastructure. It embodies a set of principles to improve how an agency conducts business, how it reaches decisions, and how it processes, uses, and communicates information. CDOT, in consultation with the Colorado Transportation Commission, has already taken a number of steps toward improved asset management. A unique Investment Category approach organizes program investments within a policy-oriented framework incorporating explicit measures of performance. Other steps taken by CDOT include updates of the statewide planning process and the program prioritization process, establishment of maintenance program levels of service, institution of customer surveys, and updates of relevant information technology applications. The recommended transportation asset management plan builds upon these established concepts, methods, information, and tools to propose specific actions over the next five years in the following areas: (1) completion of all elements of the Investment Category structure; (2) incorporation of asset management principles in CDOT's planning and programming processes, building on a tiered structuring of CDOT assets that has also been recommended in this study; (3) integration of asset management information on a GIS platform, and renewal of Information Technology strategic planning to support asset management department-wide; and (4) strengthening of program delivery mechanisms and measures. The recommended tiering of the state highway system is built around the concept of interregional corridors, because CDOT is the sole provider of significant interregional highway transportation.

This book was released on 2013 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Transportation asset management (TAM) enters a new risk-based era with the enactment of the moving ahead for Progress in the 21st Century Act, also known as MAP-21. The legislation requires a risk-and-performance based asset management plan for bridges and pavements on the national Highway system (NHS). MAP-21 also requires development of a national freight network that consists of critical corridors, facilities and connectors. As transportation agencies develop their asset management plans, it is likely that they will stratify their risks based upon the importance of the key networks, corridors and facilities. This report, the fourth in a series of five reports on risk management, examines how agencies may apply risk-based asset management practices to key networks, corridors and facilities, particularly ones moving freight. The first three reports covered an overview of risk management, multi-level management of risks and achievement of policy objectives through risk management." -- Introduction
