TRB's National Cooperative Highway Research Program (NCHRP) Report 677: Development of Levels of Service for the Interstate Highway System examines a level-of-service-based approach to describing the performance of Interstate Highway System (IHS) assets. The report also includes a template and process that state departments of transportation (DOTs) may use to implement this approach for managing their IHS assets. The appendices to NCHRP Report 677 were published on a CD-ROM that is included with the report. Titles of the appendices are as follows: Appendix A: State-of-the-Practice Research; Appendix B: Development of Levels of Service for the IHS. The CD-ROM is also available for download from TRB's website as an ISO image.
"TRB's National Cooperative Highway Research Program (NCHRP) Report 753: A Pre-Event Recovery Planning Guide for Transportation is designed to help transportation owners and operators in their efforts to plan for recovery prior to the occurrence of an event that impacts transportation systems. The guide includes tools and resources to assist in both pre-planning for recovery and implementing recovery after an event. NCHRP Report 753 is intended to provide a single resource for understanding the principles and processes to be used for pre-event recovery planning for transportation infrastructure. In addition to the principles and processes, the guide contains checklists, decision support tools, and resources to help support pre-event recovery planning."--Publisher description.
"This synthesis examines current performance-based management practices that are applied by state departments of transportation (DOTs) in highway maintenance and operations (M&O). Past studies have focused on the elements that make up a performance-based M&O approach, such as condition ratings, levels of service, performance measures, and threshold values. This study focuses on how state DOTs actually use performance-based measures to manage their highway programs."--Preface.
"TRB's Transit Cooperative Research Program (TCRP) Report 157: State of Good Repair: Prioritizing the Rehabilitation and Replacement of Existing Capital Assets and Evaluating the Implications for Transit presents a framework that builds upon a set of fundamental concepts and provides a basic set of steps for transit agencies to follow when evaluating and prioritizing capital asset rehabilitation and replacement investments. In addition to the printed report, an analytical approach and set of spreadsheet tools were developed to support the framework. These tools address how to evaluate rehabilitation and replacement actions for specific types of transit assets, and how to prioritize candidate rehabilitation and replacement actions."--Publisher's description.
"Mechanically stabilized earth (MSE) walls are an important class of infrastructure assets whose long-term performance depends on various factors. As with most all other classes of assets, MSE walls need periodic inspection and assessment of performance. To date, some agencies have established MSE wall monitoring programs, whereas others are looking for guidance, tools, and funding to establish their own monitoring programs. The objective of this synthesis project is to determine how transportation agencies monitor, assess, and predict the long-term performance of MSE walls. The information used to develop this synthesis came from a literature review together with a survey and interviews. Of the 52 U.S. and 12 Canadian targeted survey recipients, 39 and five, respectively, responded. This synthesis reveals that unlike bridges and pavements, MSE walls and retaining walls in general are often overlooked as assets. Fewer than one-quarter of state-level transportation agencies in the United States have developed some type of MSE wall inventory beyond that which may be captured as part of their bridge inventories. Fewer still have the methods and means to populate their inventories with data from ongoing inspections from which assessments of wall performance can be made. In the United States, there is no widely used, consistently applied system for managing MSE walls. Wall inventory and monitoring practices vary between agencies. This synthesis examines existing practices concerning the nature, scope, and extent of existing MSE wall inventories. It also examines the collection of MSE wall data, including the types of performance data collected, how they are maintained in wall inventories and databases, the frequency of inventory activities, and assessment practices relevant to reinforcement corrosion and degradation. Later parts of this synthesis discuss how MSE wall performance data are assessed, interpreted, and used in asset management decisions. This synthesis finds that the most well-implemented wall inventory and assessment system in the United States is the Wall Inventory Program developed by FHWA for the National Park Service. However, this system, like some others, uses 'condition narratives' in a process that can be somewhat cumbersome and subjective. Other systems use more direct numeric scales to describe wall conditions, and an advantage of such systems is that they are often compatible with those used in assessments of bridges. As experience with MSE walls accumulates, agencies will likely continue to develop, refine, and better calibrate procedures affecting design, construction, condition assessment, and asset management decisions. One portion of this synthesis is dedicated to summarizing the actions taken thus far by survey respondents to improve the long-term performance of their MSE walls. Many agencies prescribe the use of a pre-approved wall design and/or wall supplier. Other actions or policies frequently focus on drainage-related issues."--Summary.
"TRB's National Cooperative Highway Research Program (NCHRP) Report 736: Resource Allocation Logic Framework to Meet Highway Asset Preservation presents a logic framework for allocating limited highway asset preservation funds among competing demands in order to help maximize system performance. The report also presents a spreadsheet-based computational tool that implements the framework. Prototypical application scenarios and case-study examples illustrate how transportation agency staff may use the framework to assist resource allocation decision making"--Publication information.
Comprehensive and practical, Pavement Asset Management provides an essential resource for educators, students and those in public agencies and consultancies who are directly responsible for managing road and airport pavements. The book is comprehensive in the integration of activities that go into having safe and cost-effective pavements using the best technologies and management processes available. This is accomplished in seven major parts, and 42 component chapters, ranging from the evolution of pavement management to date requirements to determining needs and priority programming of rehabilitation and maintenance, followed by structural design and economic analysis, implementation of pavement management systems, basic features of working systems and finally by a part on looking ahead. The most current methodologies and practical applications of managing pavements are described in this one-of-a-kind book. Real world up-to-date examples are provided, as well as an extensive list of references for each part.
Explores a framework for applying asset-management principles and practices to managing Interstate Highway System investments.
TRB's National Cooperative Highway Research Program (NCHRP) Report 706: Uses of Risk Management and Data Management to Support Target-Setting for Performance-Based Resource Allocation by Transportation Agencies describes how transportation agencies can use risk management and data management to support management target-setting for performance-based resource allocation. As the final product of a second phase of NCHRP Project 08-70, ?Target-Setting Methods and Data Management to Support Performance-Based Resource Allocation by Transportation Agencies, ? this report supplements NCHRP 666: Target Setting Methods and Data Management to Support Performance-Based Resource Allocation by Transportation Agencies - Volume I: Research Report, and Volume II: Guide for Target-Setting and Data Management published in 2010. Volume III to this report was published separately in an electronic-only format as NCHRP Web-Only Document 154. Volume III includes case studies of organizations investigated in the research used to develop NCHRP Report 666.
Aims to encourage transportation agencies to address strategic questions as they confront the task of managing the surface transportation system. Drawn form both national and international knowledge and experience, it provides guidance to State Department of Transportation (DOT) decision makers, as well as county and municipal transportation agencies, to assist them in realizing the most from financial resources now and into the future, preserving highway assets, and providing the service expected by customers. Divided into two parts, Part one focuses on leadership and goal and objective setintg, while Part two is more technically oriented. Appendices include work sheets and case studies.
