This synthesis report provides information about the existing tools that airports use for identifying common hazards and the processes used for measuring, monitoring, and prioritizing the associated risks.

This report addresses transit agency, user, and social costs and benefits of SGR investments. The report presents an analysis methodology that utilizes and builds upon previous research performed through the Transit Cooperative Research Program (TCRP) presented in TCRP Reports 157 and 198. The guidance (presented in Chapter 3) walks through the steps for calculating the ROI for a potential investment or set of investments.

Transit Security Preparedness identifies practices transit agencies can use to improve their security to reduce their security risks, with a specific emphasis on practices related to new technologies. The report presents common themes in the approaches to security preparedness to aid transit agencies as they develop a process that fits their needs.

TCRP Synthesis 145 gathers and analyzes many of the best current practices for preventing incidents and accidents on transit buses. Their study identifies the most common and most effective technologies including a number of collision avoidance technologies such as forward collision warning, emergency braking, lane departure warnings. and electronic stability control.

This paper in the Transportation Research Record, reviews the relevant concepts and legislative requirements that link asset management, risk and resilience, and tools available to support risk-based asset management. Based on a review of the transportation asset management plans developed by 49 state departments of transportation in 2018 and 2019, the paper summarizes the approaches to the risk management section of these asset management plans and the role resilience plays. Opportunities to better integrate resilience into the risk-based asset management plans are then identified. Examples are presented that demonstrate the role of resilience-related technical performance measures that reflect decisions related to flooding in the various stages of the disaster cycle (preparedness, response, recovery, and mitigation).

This document lays out specification for service life design of highway bridges. In light of the fact that no specification or standard has been instituted in the US—except for on signature bridges and a small set of other projects, this guide aims to shed light in this regard.

The Training Hub features collects TPM training and information resources.

On this webpage, FHWA highlights numerous important documents relating to bridge management and provides contact information for the Office of Bridges and Structures. These documents include regulations and guidance on bridge performance measures, case studies from different states, and relevant NCHRP projects.

In this video captured at the 2020 TRB annual meeting—Victoria Sheehan Commissioner of the New Hampshire DOT and AASHTO’s 2019-2020 vice president leads a panel discussion on the importance of asset management. Asset Management is a strategic approach that is helping state DOTs make smarter decisions about when and where to conduct maintenance on assets, including highways, bridges, pedestrian walkways, bike routes and in some cases airports and passenger rail systems to save time and money.

Using Small Starts funding from the National Institute for Transportation and Communities (NITC), the University of Utah has produced a suite of visual analysis tools for state DOTs and other agencies. The research team, led by Dr. Nikola Markovic, utilizes GPS trajectory data to model and analyze mobility trends through interactive online animations. To demonstrate the tool's value to interested agencies, the team purchased one month of Utah trajectory data to run their software on; sample graphics of their results are included in this article.

Note: On April 7, 2020 Markovic and his colleague Mark Franz will show the value of GPS trajectory data in understanding statewide travel patterns and measuring performance in a NITC webinar Visual Exploration of Trajectory Data.

This webinar is the first of a two-part webinar series to help introduce the updated AASHTO TAM Guide. You can access the second webinar of the series: "Introducing the Updated AASHTO TAM Guide: Practitioner Perspective" here. The webinar begins with an introduction and overview of the updated TAM guide and its digital counterpart: tamguide.com. After the overview, the webinar guides the audience through two potential scenarios, showing how the TAM guide can help agencies through their decision making process.

• Scenario 1 - Building a Sustainable Asset Management Program
• Scenario 2 - Aligning with Partner Agencies

This is the second of a two-part webinar series to help introduce the updated AASHTO TAM Guide. This episode includes a half-hour recap of the guide overview and digital guide introduction for those that missed out on the first webinar in the series. After the recap, the webinar guides the audience through two potential scenarios, showing how the TAM guide can help agencies through their decision making process.

• Scenario 1 - Adding Additional Assets to Your Program
• Scenario 2 - Implementing a Multi-Objective Decision Analysis Approach
