As airport management has increased in complexity over the past few years, building information modeling (BIM) has risen as a key tool for asset life cycle management. This guidebook reviews the basic knowledge needed for airport owners and managers to implement BIM. It runs through each of the actions from pre-BIM activities like organizational assessments and financial analysis to the process of implementation and integration with existing systems. The report also includes case studies from 12 different airports and organizations, sharing their benefits and lessons learned from BIM.

This research report outlines a procedure for using crash modification factors (CMFs) to understand and quantify the effect of a transportation investment on the system. The report dives into great detail on how to select and adjust CMFs for different pavement and bridge assets, how to apply the CMFs in investment decisions, and how to develop new CMFs that account for important factors relating to the location and asset type.

This article by the Victoria Transport Policy Institute provides practical guidance for transportation equity analysis. It defines various equity types, impacts, metrics and objectives to consider, and describes ways to incorporate equity evaluation into a transportation planning process.

This publication is a compilation of the legal framework within which transportation agencies operate — and the practices employed — to reach a state of good repair. It also examines possible legal consequences of an agency's prioritization and choices of whether to repair or rebuild assets vs. closing them.

This research roadmap for rural transportation identifies a series of research needs statements and projects encapsulated within a long-term research vision. Their studies reflect the opinions of a number of different rural transportation stakeholders and communities, and the topics include everything from aviation & marine transportation to transportation administration & management to intercity transit & active transportation. The purpose of this research is to support policy-driven investment and improve the safety and efficiency of the US rural transportation network.

This publication is intended to help decision-makers with their processes for prioritization of public transit projects.

Governments, including transportation agencies, are increasingly adopting performance-based approaches to management and decision making to help achieve desired outcomes, and to encourage fiscal responsibility, accountability and transparency in
governance. As financial resources become more limited and governments focus on obtaining value for money, transportation agencies are increasingly required to make investments using cross-asset trade-offs and optimization methods to improve transparency and credibility using a performance-based approach to decision making.

Despite recent progress, there is still much to learn about performance-based decision making and the best techniques to ensure success. Many public transportation agencies seek practical examples and tools that could be deployed to advance their asset
management practices, improve the transparency of decision making, and optimize network investments. This report helps close that knowledge gap by synthesizing lessons learned with respect to performance-based decision making, and by developing a toolkit
that can help practitioners identify tools to implement for different needs within the asset management process.

This document describes the importance of determining the criticality of assets and how that determination can help set priorities.

This research report, published in 2021, highlights the knowledge gaps within the transportation industry pertaining to transportation system resilience strategies and plans. The report outlines a five-year research plan to address these shortcomings and presents the critical resilience-related issues facing practitioners today.

This research report develops a toolkit for transportation practitioners to measure the effectiveness of an agency's public involvement. A score is developed based on a couple different indicators and the agency's own perceptions. The toolkit may be used to compare different public involvement strategies and track an agency's performance over time.

Reliability is an increasingly important measure for transit performance as transit must compete with other mobility service providers. In this guide, public transit agencies and and other stakeholders are instructed on the value of measuring reliability and how to address the reliability issues for several different environments. The guide examples focus on fixed-route bus service, as it is the most common mode of transit in the US and globally, but the methodology may be applied to other modes as well. It presents the three key components of reliability: short wait times, on-time arrivals, and consistent travel times. Three perspectives are also addressed in the guide; these are customer, agency, and operator perspectives.
