The Highway Asset Management Plan (AMP) was developed in 2006 as the first phase of an effort to create a Transportation AMP for the Portsmouth City Council. The document outlines agency goals, the relevant outcomes that would help to achieve the goals, and the method of delivery. Relevant sections include goals and objectives, an asset inventory, levels of service, planning and operations, service delivery, implementation, and communication and reporting practices.

Transportation asset management is a data-intensive process and data integration is a fundamental component to improve integrated decision making. The evolution of geographic information systems and spatial technologies is providing powerful mechanisms for developing asset management decision-making products. However, many agencies are struggling with the development of these spatial products on an enterprise basis. The Transportation Research Board (TRB) Transportation Asset Management Committee (ABC40) and Spatial Data and Information Science Committee (ABJ60) hosted a peer exchange to investigate state and local agency applications of spatial technologies for asset management activities and to identify ongoing issues and research directions. Six state and local transportation agencies were selected based on their leadership and progress in the application of spatial technologies towards asset management. These six agencies were the Alaska Department of Transportation and Public facilities; the City of Edmonton, Alberta, Canada; the Kansas Department of Transportation; the New York State Department of Transportation; the New York State Thruway Authority; and the NC Department of Transportation. Prior to the peer exchange, agency participants completed an extensive questionnaire on their uses of spatial technologies, their history of implementation, and perceived benefits and issues. The peer exchange participants focused on three major issue areas in moving spatial technology applications to the next level: managing change, data integration, and communication. Upon a thorough discussion of these issues, the peer participants identified research to address three areas of interest: temporal issues, symbology, and data and visualization models. The roles of national organizations in sharing best practices and in promoting standards and open data architectures were also discussed. This circular contains the presentations of the perspectives of the six agencies, a summary of agency responses to the questionnaire, and a summary of the major issues and research directions for the future.

The two volumes included in this report--Volume I, Research Report, and Volume II, Guide for Performance Measure Identification and Target Setting--will help transportation agencies apply the concepts of performance management to their asset management efforts. Volume I describes the research effort and provides the current state of practice on the use of performance measures, principally in the context of transportation asset management. Volume II introduces a framework for identifying performance measures and setting target values, and its appendixes contain examples of performance measures and targets. The emphasis was on highway infrastructure assets. Performance measures and target values are critical to the principles of asset management to analyze tradeoffs, make investment decisions, and monitor intended effects. The report will be of interest throughout transportation agencies as an aid to effective decision making and the optimization of resources.

The aim of Part 7 of the Guide to Asset Management is to provide guidance on the application of asset management concepts and principles for the management of a broad range of diverse road related assets. The strategy framework is applicable to all road system assets. Guidance on managing the specific performance characteristics of pavements and structures is provided in Parts 5 and 6 respectively of the Austroads Guide to Asset Management.

This case study documents Indiana DOT's development of an asset management program. The program that proved to be most helpful for economic analysis at INDOT was HERS, an investment-performance model that was developed into a personalized format titled HERS-IN. Integration of HERS-IN, along with a suite of other tools, has allowed INDOT to build a comprehensive asset management program.This report is part of the FHWA Office of Asset Management's series of case studies on TAM, produced with the goal of sharing information between agencies to improve efficiency.

This circular summarizes the content of the conference’s sessions and presentations. The conference was held in conjunction with the 1st National Conference on Roadway Pavement Preservation and provided an opportunity for asset management, maintenance, and other transportation practitioners to share information, acquire new skills, and network with other professionals in this field. The opening sessions were jointly sponsored by both conferences, featuring presentations highlighting the links between pavement preservation and asset management. These sessions cited pavement preservation programs as an excellent example of applied asset management concepts and illustrated how such programs make cost-effective use of available funds with treatments that provide an improved level of service, fewer disruptions to the traveling public, and improved safety characteristics. The remainder of the 2-day conference featured presentations and facilitated discussions that supported the conference theme: Making Asset Management Work in Your Organization.

This publication contains information on several highway right-of-way assets including pavements, bridges, culverts, guardrails, and drainage structures. It describes the functional characteristics of each asset type, the data that are usually collected about the asset, general data collection methods, equipment and/or technology that is employed to acquire the data, the formats and standards applied to data transfer and storage, how the information is used for condition assessment, and suggests performance and condition standards.

This document contains guidelines for and background notes on measurement and reporting of rutting or transverse profiles for road network management purposes in Australia and New Zealand. The guidelines define rutting as a longitudinal surface depression usually in a wheel path. The guidelines have been prepared in the context of measuring rutting either manually with a straight edge or using a vehicle mounted non-contact multi-sensor transverse profile measurement device. Regardless of the method of measurement, the guidelines express a preference for rut depth to be reported with reference to a 2 m straight edge. This is consistent with the HDM-4 approach. A standard reporting interval of 100 m is favoured. The guidelines discuss the frequency and extent of network rutting surveys, and are intended as a basis for the preparation of specifications for surveys of network rutting. Verification procedures for profilometers, and limits on repeatability and bias for rutting reports are included. The document also discusses the uses of rutting data in road pavement management at network and project levels and provides guidance on analysis techniques for rutting data for different applications. A glossary of terms used in measuring road pavement rutting is also included.

This document contains guidelines for and background notes on network level measurement and reporting of pavement cracking data for road network management purposes in Australia and New Zealand. The guidelines discuss the types and causes of cracking, the frequency and scope of network cracking surveys, and the methods available for network level cracking surveys. The guidelines describe four current principal methodologies for measuring surface cracking at a network level in Australia and New Zealand, viz. detailed walk-over inspections, drive-over windscreen surveys, manual post-interpretation of video images of pavement surfaces, and fully automated techniques involving high-resolution imaging and automated crack recognition. The guidelines recognise and define three parameters for reporting cracking, viz. dominant crack type, severity (crack width), and extent (proportion of total surface area cracked). The guidelines are intended as a basis for a consistent approach in Australia and New Zealand. Verification procedures for cracking measurement methods are covered, and repeatability and bias are briefly discussed. A glossary of terms used in network level assessment of road surface cracking and a summary of a literature review of practices for collecting cracking data are included. (a)

This report contains guidelines for and background notes on the conduct of response type and profile-based roughness measurement for road network management purposes in Australia and New Zealand. The guidelines define roughness as being concerned with road surface profile wavelengths between 0.5 metres and 50 metres. The guidelines describe two broad measures of roughness, viz NAASRA Roughness Meter (NRM roughness values in counts per kilometre) and the International Roughness Index (expressed in units of metres per kilometre), and mark the introduction to Australasia of Lane IRI as a standard form of reporting road pavement roughness. A standard reporting interval of 100 metres is favoured. The guidelines discuss the frequency and extent of network roughness surveys, and are intended as a basis for the preparation of specifications for network roughness surveys. Verification procedures for inertial profilometers, testing frequencies, and limits on repeatability and bias for roughness reports are included. A glossary of terms used in measuring road roughness is also included. (a) Austroads Project AP1009
