Breakout #8

Breakout Session #8

Traffic Signal Control with Connected and Automated Vehicles (CAVs)

Tuesday, July 19

Room- Continental 9


  • Henry Liu, University of Michigan
  • Larry Head, University of Arizona


In this breakout group, we will discuss and investigate the transitional traffic signal control issues from very low percentage of CAVs (i.e. current state-of-the-practices) to high percentage of CAVs (i.e.), and eventually to fully automated transportation systems, in that traffic signal control may no longer be needed. Although the duration of the transitional period is uncertain, it is important for both traffic management agencies and traffic control industry to understand what might be happening during the transitional process and how we can better prepare and facilitate the transition. On that, we would like to solicit inputs not only from academic researchers, but also practicing engineers from government agencies as well as from traffic control industry.

Researchers, Engineers from Traffic Management Agencies, and Engineers from Traffic Control Industry

Goals of the session
The goal of this breakout group is to gain deeper understanding of the transitional traffic control issues as we moving forward with CAVs.

Planned outputs
Problem statements on the transitional traffic control issues with increasing percentage of CAVs in the future.

Format and structure of the session
Two 90-minute Sessions, one for state-of-the-art research presentations and the other one for panel discussion with engaging audience.


  1. Multi-Modal Considerations in CAV Traffic Control, Larry Head, University of Arizona
  2. Next Generation Traffic Signal Systems with Connected and Automated Vehicles, Henry Liu, University of Michigan
  3. Core Technologies for Cooperative Vehicle Adaptive Signal Control Systems (CoVASS), Young-Jun Moon, Chief Director, Korea Transport Institute (KOTI)
  4. TBD

Session 2: Future Research Directions on Traffic Signal with CAVs

The second session will be a facilitated development of research problem statements, i.e., discuss research ideas - that could be published or submitted to TRB/USDOT.
