Reducing Greenhouse Gas Emissions: A Guide for State DOTs | Research ReportEmissions, Environment
This WebResource describes methods State DOTs may implement to assess and reduce their GHG emissions. The resource includes self-assessment tools, an overview of climate change issues, a framework for addressing GHG emissions, and numerous resources and links. The report organizes around nine functional areas of the agency, with cross-cutting topics to pull it all together. Through the discussions, tools, and resources in each section, the report provides support for reducing emissions across all stages of a project, from policy and planning to construction and maintenance. It also reviews stakeholder communication, partnerships with other agencies, and federal or state requirements. Readers may use this guide and its flexible presentation for addressing specific areas within an agency or to adopt an agency-wide approach.
Guide to Pedestrian Analysis | Research ReportSafety, System Performance
The NCHRP Research Report 992: Guide to Pedestrian Analysis spells out several methods for conducting pedestrian traffic analyses. The report identifies analyses based on volume, safety, operations, and service quality. All of these analyses form a broader picture focused on improving active transportation and multimodal transportation in cities and regions around the country. The report presents evaluation methods which align with the Highway Capacity Manual. In addition to the report content, the researchers also developed and identified supplemental resources including presentations from a peer exchange workshop, computational engines, and an additional report on HCM pedestrian methods for sustainable and safe communities.
Example Practices for Performance-Driven Programming | Research ReportAsset Management, Safety, System Performance
This report promotes the experiences of four State DOTs and five MPOs as they apply performance-based planning and programming and align investment decisions with federal performance measures. Other agencies and organizations may use these examples to advance their own practices, specifically in the areas of safety, infrastructure condition, and system performance.
This 2022 California TAMP is a Draft for Public Comment. The California TAMP describes the vision for how good asset management will help to deliver broad transportation goals and fundamental objectives supported by information on current asset conditions, the desired conditions in the future, and the likely conditions given future funding scenarios.The TAMP is also a key requirement of California law and of Federal regulations. California law (Senate Bill 486) requires Caltrans to develop an asset management plan for the State Highway System, as determined by the California Transportation Commission. Federal regulations (23 CFR 515) require an asset management plan for pavements and bridges on the National Highway System, including those owned by Caltrans and other federal, state and local agencies. This document is intended to meet both sets of requirements.
TCRP Synthesis 158: Cybersecurity in Transit Systems | Research ReportSafety
As more systems go online and more workers shift to remote work, cybersecurity issues only continue to rise in risk and intensity. This research report identifies and tracks such trends. Findings cover teleworking and remote workers, contactless customer service, real-time information updating, transit-on-demand services and platforms, and cyber resilience within transit agencies.

ACRP Research Report 214: BIM Beyond Design Guidebook | Guide/ManualAsset Management, Organizational Management
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.
