Specifications include, but are not limited to: Task 1. Conduct a literature review to identify CAV technologies that influence OD, both currently available and in development. This task may include discussion with original equipment manufacturers (OEMs) or AV technology companies. Identify existing gaps in research on the influence of CAV technologies on OD. Determine lessons learned from CAV testing and deployment activities. Task 2. Identify infrastructure modifications that facilitate deployment of CAV. Modifications ready for application should be distinguished from those pertaining to technologies still in development. Performance data from CAV testing and deployments shall also be considered in identifying infrastructure modifications. Submit a technical memorandum summarizing the findings of Tasks 1 and 2 with a detailed outline of the proposed guidelines for NCHRP review. NCHRP approval of the memorandum is required before work on Task 3 may begin. Task 3. Develop draft guidelines for aligning infrastructure modifications with technology influencing OD. The guidelines shall be designed to enable IOO to identify and prioritize potential modifications that enable the deployment of CAVs. The draft guidelines shall also include proposed performance metrics to evaluate the improvements in OD offered by the infrastructure modifications. These metrics should consider impacts to both existing and future road users, levels of vehicle automation, and safety and mobility benefits offered by CAV technologies. Task 4. Prepare an interim report that documents the research performed in Tasks 1 through 3. Following the review of the interim report by the NCHRP, the research team will be required to make a presentation to NCHRP. Work on Phase II will not begin until the interim report is approved and the Phase II work plan is authorized by the NCHRP. The decision on proceeding with Phase II will be based on the contractor’s justification of the updated work plan. Note: The contractor shall submit the Phase I interim report within 6 months from contract award and meet with NCHRP within 2 months of report submission. The meeting is expected to be in-person and held in Washington, DC. Whether in-person or online, NCHRP will host the meeting and be responsible for any panel member costs to attend meeting. PHASE II Task 5. Conduct four to eight representative case studies using the draft guidelines. This task may feature case studies involving simulation, closed course, or on-road data collection to validate the guidelines. The case studies shall feature a diverse range of roadway environments, functional classes, and vehicle automation levels. Relevant stakeholders may be engaged to assist with conducting the case studies. Task 6. Analyze case study data and revise the guidelines. Data analysis will feature validating against the guidelines and outline the data requirements for IOO seeking to implement infrastructure modifications. Data requirements shall consider safety, mobility, equity, and accessibility metrics. Task 7. Prepare a final deliverable that documents the entire research. Deliverable will include (1) a research report documenting the work performed in the project and used to develop the guidelines, (2) the guidelines, (3) presentation material, and (4) technical memorandum on implementation (see Special Note C). 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.
