Lesson

Maintain active communications regardless of system states, faults, or emergency kill switches to ensure the safety and function of cooperative adaptive cruise control truck platoons.

Developing an operational concept to manage truck cooperative adaptive cruise control (CACC) systems on I-710 in California.

Lesson Learned

There are some key considerations in the deployment of CACC:
  • Coordination strategies for CACC should be based on local conditions. What works in one corridor may not work in another.
  • Mitigation of negative effects of cut-ins is important. These events are an issue with steady-state cruising because they cause a temporary string split maneuver and cause a disruption.
  • System states, fault conditions, and emergency kill switches must be designed to keep the DSRC broadcast active while indicating what is occurring as all following trucks will be impacted.
  • CACC systems must incorporate an ability for the lead truck driver to send instructions (e.g., lane change) or warnings (e.g., road hazards) to following trucks.
