This research and policy guidance focuses attention on ten areas and safety recommendations which will save lives and improve transportation safety. These areas are: distractions, alcohol and drug impairment, shipment of hazardous materials, positive train control, speeding-related crashes, aircraft flight operations, collision avoidance systems, fatigue-related accidents, medical screening for sleep apnea, and strengthening occupant protection. Under each of these categories, the document presents recommendations for aviation, highway, marine, rail, intermodal, and pipeline modes.

This report extends and implements the results of NCHRP Report 806: Cross-Asset Resource Allocation and the Impact on System Performance. Case studies were used to illustrate key issues in implementing a cross-asset resource allocation approach, and the lessons learned were then used to improve the guidance and tools developed in NCHRP Report 806.

This report provides a guideline for identifying right-sizing opportunities where greater social and economic value can be realized by repurposing, reusing, or fundamentally resizing existing transportation system assets.
In addition to Report 917, supplementary products are available, including:

• Web-Only Document 263: White Papers for Right-Sizing Transportation Investments
• A Powerpoint presentation for decision-makers
• Spreadsheet model
• Spreadsheet model example
• A technical appendix

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.

This project proposes a framework for comprehensive, risk-based asset management approach for retaining walls. It includes a sensing strategy for the walls and geotechinical environment, a reliability framework, and an inspection manual to reflect the strategies and risk analysis.

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.
