The American Association of State Highway and Transportation Officials (AASHTO) and the Transportation Research Board (TRB) Committee on Safety Performance Analysis developed a strategic plan for future editions (SPFE) of the AASHTO Highway Safety Manual (HSM) to document the process of identifying research needs, substantiating funding, tracking research progress, reviewing technical content, and finalizing an adoption process for a new edition of the HSM. Although the SPFE provides overall guidance for development of a new edition, numerous questions and research needs have been identified during the process of developing the second addition of the HSM.

Early plans for HSM implementation and institutionalization, along with support from numerous stakeholders, have helped develop the state of the practice of data-driven safety analysis. Based on transportation professionals’ use of the HSM and other safety analysis guides and resources, there is an immediate need to develop a roadmap for the HSM that will build on lessons learned from the evolution to date of this field (i.e., https://domesticscan.org/scans/16-01-leading-practices-in-the-use-of-the-highway-safety-manual-for-planning-design-and-operations/; https://safety.fhwa.dot.gov/hsm/fhwasa16106/; https://apps.trb.org/cmsfeed/TRBNetProjectDisplay.asp?ProjectID=2974) and will support expansion to a wider range of applications and users. Additionally, the roadmap could help identify the HSM community’s preference for tools and technical content to be included in the next edition of the HSM. 


The objective of this project is to develop an HSM roadmap that will guide content, publication, implementation, and other aspects of the HSM to expand its use throughout the transportation facility lifecycle and to include a wider range of users and facility types.


Task descriptions are intended to provide a framework for conducting the research. The NCHRP is seeking the insights of proposers on how best to achieve the research objective. Proposers are expected to describe research plans that can realistically be accomplished within the constraints of available funds and contract time. Proposals must present the proposers’ current thinking in sufficient detail to demonstrate their understanding of the issues and the soundness of their approach to meeting the research objective. 

The research plan should (1) include a kick-off teleconference with the research team and NCHRP convened within 1 month of the contract’s execution; (2) address how the proposer intends to satisfy the project objective; (3) be divided logically into detailed tasks necessary to fulfill the research objective and include appropriate milestones and interim deliverables; and (4) incorporate opportunities for the project panel to review, comment on, and approve milestone deliverables. 

Accomplishment of the project objectives will require at least the following tasks.  


Task 1. Collect and synthesize information to inform the development of a roadmap. At a minimum, efforts should include:

  • Identify gaps in knowledge (content and awareness), methods, applications, and transportation industry usage of the HSM that will inform the framework for developing and implementing future editions of the HSM.
  • Identify transportation professionals’ preferences for a longer-term vision of the methods, content, format, supporting tools, and other materials for the HSM.
  • Coordinate with members of committees and panels involved with the development of other publications related to the design and operation of transportation facilities to align content development of future editions of the HSM with those documents.  

Task 2. Propose an annotated outline for content of the HSM roadmap.

Task 3. Prepare an Interim Report that summarizes results from Tasks 1 and 2, refines the Phase II work plan, presents key issues, and recommends priorities to address in future editions of the HSM.

Note: Following a 1-month review of the Interim Report by the NCHRP, the research team will be required to meet with the NCHRP project panel to discuss the interim report, if necessary. Work on Phase II of the project will not begin until authorized by the NCHRP.


Task 4. Develop a roadmap that, at a minimum, addresses the following elements:

  • Future HSM content, including:
    • Ways to help ensure future research results are compatible with the HSM (e.g., research methodology, study quality);
    • Future research needs to fill HSM gaps identified in Task 1;
    • Guidance for how to conduct future research (e.g., advances in statistical methods and safety analysis methods; ensure that research is pilot tested in other jurisdictions; test new research against work already in the HSM to ensure results are not conflicting or counterintuitive);
    • Expand HSM use throughout the transportation facility lifecycle and to include a wider range of users and facility types;
    • Incorporate the Safe System approach; and
    • Surrogate and nontraditional analyses and performance metrics.
  • Format and structure (e.g., electronic vs. hard copy; publish parts individually or together; multiple versions tailored for practitioners vs. researchers).
  • Future HSM publication considerations (e.g., frequency of updates, timeliness of incorporating new research results).
  • Opportunities for linkages with emerging safety research results.
  • Implementation program (e.g., outreach, training, tools, website content, and other implementation needs).

Task 5. Conduct a stakeholder webinar and revise the draft roadmap based on stakeholder feedback, with emphasis on producing a practical/useable document.

Task 6. Prepare a final deliverable that documents the entire research effort. Final deliverables should include (1) a final research report documenting the entire research effort and findings; (2) HSM roadmap; (3) prioritized recommendations for future research needs; (4) outreach materials, including a PowerPoint presentation, to inform HSM-related stakeholders about the roadmap; and (5) technical memorandum on implementation (see Special Note I).

Note: Following receipt of the draft final deliverables, the remaining 3 months shall be for NCHRP review and comment and for research agency preparation of the final deliverables.


A. The Information and Instructions for Preparing Proposals for the Transportation Research Board’s Cooperative Research Programs were revised in May 2022. Please take note of the new and revised text which is highlighted in yellow. 

B. Proposals must be submitted as a single PDF file with a maximum file size of 10 MB. The PDF must be formatted for standard 8 ½” X 11” paper, and the entire proposal must not exceed 60 pages (according to the page count displayed in the PDF). Proposals that do not meet these requirements will be rejected. For other requirements, refer to chapter V of the instructions. 

C. The Information and Instructions for Preparing Proposals for the Transportation Research Board’s Cooperative Research Programs have been modified to include a revised policy and instructions for disclosing Investigator Conflict of Interest. For more information, refer to chapter IV of the instructions. A detailed definition and examples can be found in the CRP Conflict of Interest Policy for Contractors. The proposer recommended by the project panel will be required to submit an Investigator Conflict of Interest and Disclosure Form as a prerequisite for contract negotiations. 

D. Proposals will be rejected if any of the proposed research team members work for organizations represented on the project panel. The panel roster for this project can be found at https://www.mytrb.org/OnlineDirectory/Committee/Details/6689. Proposers may not contact panel members directly; this roster is provided solely for the purpose of avoiding potential conflicts of interest. 

E. Proprietary Products - If any proprietary products are to be used or tested in the project, please refer to Item 6 in the Information and Instructions for Preparing Proposals. 

F. Proposals are evaluated by the NCHRP staff and project panels consisting of individuals collectively knowledgeable in the problem area. The project panel will recommend their first choice proposal considering the following factors: (1) the proposer's demonstrated understanding of the problem; (2) the merit of the proposed research approach and experiment design; (3) the experience, qualifications, and objectivity of the research team in the same or closely related problem area; (4) the plan for ensuring application of results; (5) how the proposer approaches inclusion and diversity in the composition of their team and research approach, including participation by certified Disadvantaged Business Enterprises; and, if relevant, (6) the adequacy of the facilities. A recommendation by the project panel is not a guarantee of a contract. The National Academy of Sciences (NAS - the contracting authority for the National Academies of Sciences, Engineering, and Medicine) will conduct an internal due diligence review and risk assessment of the panel’s recommended proposal before contract negotiations continue. 

Note: The proposer's approach to inclusion and diversity as well as participation by Disadvantaged Business Enterprises should be incorporated in Item 11 of the proposal.
