Discussion of the Transit analysis for the Highway and Transit Conditions and Performance Report to Congress, Revising the Fixed Guideway Modernization Formula, and Implementing a SGR fund designed to sunset in 20 years, linked to SGR planning requirements (an asset management plan)

A pilot scale culvert information management system (CIMS) was developed for the New Jersey Department of Transportation to comply with requirements stipulated by the Governmental Accounting Standards Board, GASB-34, and new federal stormwater regulations. The condition states of culverts are used to express the extent of their deterioration and survival probabilities. A financial analysis model was developed on the basis of the remaining value of culverts and the user cost of failures. Different rehabilitation options were discussed, and recommendations were made for deteriorated culverts on the basis of financial analysis. The pilot CIMS can analyze prescribed culvert information and make decisions to inspect, rehabilitate, or replace culverts or to do nothing at project and network levels. At the project level, this is achieved by comparing inspection, rehabilitation, or replacement costs with risks and costs associated with failure. At the network level, the associated costs are optimized to meet annual maintenance budget allocations by prioritizing culverts needing inspection and rehabilitation or replacement. The CIMS has three major computer software components: databases, user interfaces, and functionality modules. Modules include inlet–outlet structures, culvert segments, culvert assessment, and optimization. Users are able to retrieve culvert and inlet–outlet structure physical and financial information and to generate reports vis-à-vis location, road, and milepost for condition state and assets needing immediate repair. The CIMS will also do the following operations: maintain an up-to-date inventory of eligible infrastructure assets; perform maintenance of eligible infrastructure assets for a given budget using a replicable basis of measurement and measurement scale; and summarize results, noting any factors that may influence trends in the information reported.

A case study which highlights the importance of asset management and performance management in the context of decision making. The report describes practices by which transportation agencies can effectively integrate data, and use data to drive their decision-making processes, thus increasing efficiency.

The focus of this document is on how to best manage the physical bridge assets. It provides guidance on the establishment and maintenance of bridge asset inventories, and on the monitoring of asset performance. It discusses the need for agencies to measure asset performance against objectives, and therefore is primarily concerned with condition data collection and performance modelling at a network level.

This study gathers information on current practices that senior managers at transportation agencies use to make network-level decisions on resource allocations for their bridge programs. In particular, the study explores how agency bridge management systems are employed in this process. Information was gathered through a review of literature on U.S. and international bridge management, a survey of U.S. and Canadian transportation agencies, and 15 in-depth interviews with state department of transportation executive and bridge managers.

This fifteenth volume of NCHRP Report 525: "Surface Transportation Security" is a guide referred to as CAPTA, which stands for Costing Asset Protection: An All Hazards Guide for Transportation Agencies. CAPTA supports mainstreaming an integrated, high-level, all-hazards, National Incident Management System (NIMS)-responsive, multimodal, consequence-driven risk management process into transportation agency programs and activities by providing a convenient and robust planning tool for top-down estimation of both capital and operating budget implications of measures intended to reduce risks to locally acceptable levels. CAPTA is intended for use by senior managers whose jurisdiction extends over multiple modes of transportation, multiple asset classes, and many individual assets. The CAPTA methodology provides a means for moving across transportation assets to address system vulnerabilities that could result in significant losses given the threats and hazards of greatest concern. This guide was reviewed by many state and local agencies and was pilot tested by the Maryland Department of Transportation (DOT), the Massachusetts Bay Transportation Authority (MBTA), and the Virginia DOT.

TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2108 includes 13 papers that explore culvert information management system, opportunistic behavior in road maintenance markets, evaluating pavement interventions, performance indicators for the service life of thin hot-mix asphalt overlays, life-cycle costing of pavement surface retexturing with shotblasting, and performance-based uniformity coefficient of chip seal aggregate. This issue of the TRR also examines chip seal maintenance, crack sealant material and reservoir geometry of bituminous overlays, wooden bridge preservation treatment, penetrating sealers for reinforced concrete bridge decks, underwater bridge inspection practices, infrared imaging of subsurface of concrete bridges, and rolled erosion control products for roadside maintenance.

The aim of Part 3 of the Austroads Guide to Asset Management (Asset Strategies) is to provide guidance on the frameworks and principles of asset strategies. Asset strategies articulate the proposed management of the capacity, condition and use of road system assets to achieve the level of road system performance which is acceptable, affordable and sustainable to meet the needs of stakeholders and the community. The focus of Part 3 is to assist road agencies to develop performance-driven asset management strategies which achieve community-driven outcomes. The Guide presents an integrated strategy framework comprising: an overarching road system management strategy, a road investment strategy, an infrastructure preservation strategy and road use management strategies.

Asset Valuation and Audit is the title of part 8 of the Austroads Guide to Asset Management. It provides a comprehensive guidance for asset managers in the road industry. Part 8 Asset Valuation and Audit provides guidance on how to undertake an asset valuation to assist the asset manager with long-term asset and financial management requirements, how an auditor undertakes an audit of infrastructure and how to present information on financial sustainability of the agency to external stakeholders and other customers by use of public reports and other media. Part 8 Asset Valuation and Audit complements the Australian Infrastructure Financial Management Guidelines published by the Institute of Public Works Engineering Australia.

This document is part 2 of Guide to Asset Management, and provides guidance on how community and stakeholder requirements can and should influence asset management undertaken by road agencies. As roads are provided as a service to the community, community and stakeholder requirements are the means by which that service is defined. Only through the identification, translation and integration of these requirements (as appropriate) into organisational and asset objectives can road agencies target resources effectively to deliver that service. The direction and clarity provided by an effective framework for understanding community benefits and expectations (i.e. requirements), aids in the development of policies and strategies related to road asset management and performance. With an emphasis on current Australian and New Zealand practice this part provides: 1. an understanding of why it is important to have community and stakeholder input to asset management; 2. an overview of issues and approaches to obtaining and considering community and stakeholder requirements for asset management; 3. advice on how to establish and link community and stakeholder requirements to road agency outcomes.
