Book Description
In an era characterized by funding limitations, increased stakeholder participation, and the need for increased accountability and transparency, transportation agencies seek to ensure that comprehensive evaluation processes are identified and used for decision-making. Consistent with such processes is the incorporation of multiple performance criteria from different program areas, optimization of decisions under constrained budgets, and investigation of trade-offs between program areas, performance measures, budgetary levels, risk levels, and performance thresholds. To help INDOT carry out these processes, this study developed theoretical constructs for scaling and amalgamation of the different performance measures, and for analyzing the different kinds of trade-offs. The scaling of performance measures yields a consistent or dimensionless unit to make them comparable. Amalgamation combines the weighted and scaled performance measures to yield a single utility value that represents the overall desirability of a candidate project. This report documents, with examples, a number of alternative methods for scaling and amalgamation. Also, recognizing that project outcomes are not always known with certainty, the analysis was done for the deterministic (certainty) as well as the probabilistic (uncertainty) scenarios. Finally, the report describes how INDOT can carry out an investigation of trade-offs such as changing the performance threshold and shifting budgets from one program area to another. To facilitate implementation, the report includes a set of spreadsheets that are based on hypothetical project data.

Book Description
As part of the ongoing evolution towards integrated highway asset management, the Indiana Department of Transportation (INDOT), through SPR studies in 2004 and 2010, sponsored research that developed an overall framework for asset management. This was intended to foster decision support for alternative investments across the program areas on the basis of a broad range of performance measures and against the background of the various alternative actions or spending amounts that could be applied to the several different asset types in the different program areas. The 2010 study also developed theoretical constructs for scaling and amalgamating the different performance measures, and for analyzing the different kinds of trade-offs. The research products from the present study include this technical report which shows how theoretical underpinnings of the methodology developed for INDOT in 2010 have been updated, upgraded, and refined. The report also includes a case study that shows how the trade-off analysis framework has been calibrated using available data. Supplemental to the report is Trade-IN Version 1.0, a set of flexible and easy-to-use spreadsheets that implement the trade-off framework. With this framework and using data at the current time or in the future, INDOT's asset managers are placed in a better position to quantify and comprehend the relationships between budget levels and system-wide performance, the relationships between different pairs of conflicting or non-conflicting performance measures under a given budget limit, and the consequences, in terms of system-wide performance, of funding shifts across the management systems or program areas.

Book Description
Transportation asset management delivers efficient and cost-effective investment decisions to support transportation infrastructure and system usage performance measured in economic, social, health, and environmental terms. It can be applied at national, state, and local levels. This distinctive book addresses asset management for multimodal transportation, taking account of system component interdependency, integration, and risk and uncertainty. It sets out rigorous quantitative and qualitative methods for addressing system goals, performance measures, and needs; data collection and management; performance modeling; project evaluation, selection, and trade-off analysis; innovative financing; and institutional issues. It applies as easily to static traffic and time-dependent or dynamic traffic which exists on a more local level. It is written for transportation planners, engineers, and academia, as well as a growing number of graduate students taking transportation asset management courses.

Book Description
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.

Book Description
Although transportation agencies in the U.S. have been developing Asset Management Systems (AMS) for specific types of infrastructure assets, there are several barriers to the implementation of AMS. This paper documents the development of a generic methodology for quantifying the benefits derived from implementation of AMS and justifying investment in AMS implementation. The generic methodology involves three analysis methods: descriptive analysis, regression analysis, and benefit-cost analysis. This paper demonstrates how the methodology can be applied to evaluate the implementation of a pavement management system in terms of efficacy, effectiveness, and efficiency (3Es).

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Report 544: Environmentally Sensitive Channel- and Bank-Protection Measures examines environmentally sensitive channel- and bank-protection measures and includes recommended design guidelines for their application and a selection system for helping to determine the most appropriate channel- and bank-protection measure. The selection system is presented as an interactive software program entitled "Greenbank," which can be found on the accompanying CD-ROM (CRP-CD-58). The selection system software (CRP-CD-58) is available for download in an ZIP format.
