This report documents current practices used by transportation agencies to make investment decisions about low-volume roads. Current transportation asset management practices for low-volume roads typically use asset condition, traffic, and safety metrics to prioritize investment decisions for preservation, maintenance, repair, and replacement projects. However, these metrics do not fully measure the significant value for the wider economy and society that low-volume roads can provide.

This ACRP Impacts on Practice article explores the impact ACRP Research Report 69: Asset and Infrastructure Management for Airports -- Primer and Guidebook has had on managing airport assets. An asset management director at Cincinnati/Northern Kentucky International Airport (CVG) utilized this report to incorporate and directly correlate asset management with CVG’s overall strategic plan. This report explains how to holistically develop an asset management policy as well as asset management strategies, objectives, and plans to achieve the airport’s overall strategic goals. It also provides a roadmap for how to assess and improve an airport's asset management initiatives.

TRB's Transit Cooperative Research Program (TCRP) Research Report 198: The Relationship Between Transit Asset Condition and Service Quality documents the development of a quantitative method for characterizing service quality and demonstrates how this quantitative measure varies with changes in asset condition. It provides guidance on how asset condition and transit service quality relate in terms of investment prioritization.
Three Excel spreadsheets–a simplified Effective Journey Time (EJT) Calculator, a comprehensive EJT Calculator, and a worked example demonstrating the use of the comprehensive EJT Calculator—provide quantitative methods. Transit agencies may use this report and tools to better manage existing transit capital assets and make more efficient and effective investment decisions.

This document provides transparency to to the public and aids state DOTs in computing bridge condition measures. It outlines the calculation steps for determining the minimum bridge condition levels by state and the DOT's progress towards their targets.

This document provides transparency to to the public and aids state DOTs in computing pavement condition measures. It outlines the calculation steps for determining the minimum pavement condition levels by state and the DOT's progress towards their targets.

This report documents a collaborative regional asset management pilot project across infrastructure systems (roads, bridges, water, wastewater, stormwater, electric, gas, and broadband) and asset owners.

Georgia DOT's 2018 TAMP focuses on pavements and bridges, the largest share of Georgia’s transportation assets. GDOT believes the key drivers of an effective TAMP include:
-Clear links between policy, goals/objectives and decisions at all levels within the Department
-An understanding of the connection between proposed investments and expected results
-A long-term view of asset performance
-Feedback loops linking observed performance to planning and programming decisions
-Integration of data to support and drive data-driven decisions
-Georgia DOT leadership’s commitment

​As part of its long-term strategy for efficiently maintaining the 25,062 highway lane miles and 2,976 bridges under its jurisdiction, the New Mexico Department of Transportation compiled and released a 94-page Transportation Asset Management Plan in mid-April 2018 that advocates for $40 million a year in bridge revitalization funding and $294 million annually for interstate and non-interstate pavement funding. This is NMDOT's first TAMP.

The 2018 IowaDOT TAMP focuses on management, preservation, and improvement of the existing highway system. The TAMP also connects to other IowaDOT plans, Iowa in Motion and system/modal plans to Iowa DOT’s Five-Year Transportation Improvement Program (Five-Year Program). Iowa in Motion defines a vision for the transportation system over the next 20 years, while the Five-Year Program identifies specific investments over the next five years. The TAMP has a 10 year planning horizon and helps ensure that investments in the Five-Year Program are consistent with Iowa DOT’s longer-term vision.

The AASHTO TAM Portal is a transportation asset management knowledge portal: a searchable database of links to a wide range of resources related to transportation asset management. The interactive portal is designed to provide transportation asset management practitioners with the ability to search and access relevant documents and/or web links to information from multiple sources. The report documents the results of the activities carried out under the continuation of NCHRP Project 08-36(125).

This long range plan presents a framework to aid Connecticut in their decision making process for the near- and long-term. It includes an assessment of the current system, financial analyses, and ultimately strategies to meet the agency's goals and vision. CTDOT relied on partners in the public and private sectors and throughout their communities to develop this document. It addresses all transportation modes: highways, bridges, rail, bus, airports, ports, urban systems, and regional trails as well as the distinct needs of people in freight, active, and public transport.

This document details the Quality Management Plan (QPM) for an FHWA study collecting and analyzing 7500 miles of pavement condition data on the Interstate System. The project seeks to understand and verify the data stored in the Highway Performance Monitoring System (HPMS) by checking it with a national baseline, and this plan intends to control the quality of the project's data collection. This QMP outlines the standards and protocols for their data deliverables, explains how manual raters are certified, describes equipment calibration, certification, and verification, reports on the data quality checks, and finishes with a review of the data deliverables.
