State-of-the-Art Review of Cooperative Automated Transportation (CAT) Systems
[ NCHRP 20-24 (Administration of Highway and Transportation Agencies) ]

  Project Data
Funds: $674,998
Staff Responsibility: B. Ray Derr
Research Agency: WSP USA, Inc.
Principal Investigator: Stephen Kuciemba
Effective Date: 7/16/2019
Completion Date: 7/15/2021



The objective of this research is to document and disseminate lessons learned from CAT system deployments (both domestic and international) that state DOT executive leadership can apply to decisions affecting their agency. These decisions will include the areas of advancing policies, legislation, and regulations; developing scenarios for planning; developing technical materials (on topics such as system design, upgrading transportation and communication infrastructure, data management, procurement, and security); evaluating alternative funding mechanisms; and establishing and maintaining industry partnerships.


The work is underway.




Task 1. Kick-Off Meeting


The contractor will participate in a meeting among the project oversight panel, CAT Coalition leadership, U.S. DOT staff, and other partners to update the panel members’ situational awareness and make decisions regarding subsequent tasks. The 1.5 day meeting will be held June 27-28, 2019 in Las Vegas, NV with 15-20 participants. Travel arrangements for non-research-team participants will not be the responsibility of the contractor.


The meeting agenda is expected to include a review of outcomes from the FHWA’s National Dialogue on Highway Automation, review of CAT Coalition activities, identification of key topics that should be emphasized in the Task 2 scans, discussion of likely sites for the Task 2 scans, and discussion of approaches to dissemination (e.g., videos, presentations to AASHTO, National Operations Center of Excellence webinars, TRB Annual Meeting sessions). The key topics should relate to the five areas of decision-making mentioned in the project objective and could include the infrastructure investments (both physical and digital) required to enable connectivity; accessibility and performance of CAT systems in different environments (urban, suburban and rural); the policy, legislative and regulatory framework needs to ensure uniform operations across jurisdictions; modifications required to short-, medium- and long-term agency planning forecasts to account for mixed fleets and evolving trip patterns; and the impacts on multi-modal systems.


Task 2. Domestic and International Scans


In this task, the contractor will lead scans at sites that have successfully addressed the key topics identified in Task 1. The sites could be real-world or proving ground deployments. Similarly to NCHRP Project 20-68A, US Domestic Scan Program, the contractor will, for each scan:

  • Establish scan team membership based on recommendations from the Task 1 meeting (opportunities should be provided for a limited number of self-pay auxiliary members to participate if they are expected to add value to the effort);
  • Develop scan itinerary, identifying what would be learned at each site;
  • Provide logistical support for scan team members, including travel, lodging, and per diem expenses (these will draw upon project funds);
  • Prepare draft and final scan scoping materials, desk scan reports, and summary and full scan team reports;
  • Guide the scan team throughout the scan and serve as subject matter expert;
  • Secure NCHRP review and approvals of scan scoping and reporting documents; and
  • Maintain accounts of costs for each scan.


Task 3. National CAT Summit


A summit will be held at the 2020 ITS World Congress Meeting in Los Angeles, CA (October 4-8) to showcase the findings from Tasks 1 and 2. The contractor will be expected to:

·            Provide logistical support for select participants (estimated at 15 people including the NCHRP panel and CAT Coalition leaders), including travel, lodging, and per diem expenses (these will draw upon project funds);

·            Recommend a format for the summit. It is expected that there will be breakout sessions on the decision areas mentioned in the project objective.

·            Prepare presentation materials supporting the selected format that summarize the activities and findings of the project.

·            Develop preparatory materials for the decision area breakout sessions, including questions to be resolved or to illuminate critical issues.

·            Take notes for the breakout sessions. Summit invitees will likely be able to facilitate the sessions.


Task 4. Final Deliverables


The contractor will develop, at a minimum, the following deliverables:

  • A succinct and practical report that will can inform state DOT decision-making regarding the deployment of CAT systems. The report should describe suitable follow-on activities that can advance the dissemination and implementation of the material and recommend approaches for continuing this type of information gathering.
  • An executive summary.
  • Microsoft PowerPoint presentations that can be used by panel members and others to convey the findings.
