Human Factors Issues Associated with ‘Connected Automation’ Applications


  • David Yang, Federal Highways Administration
  • Brian Philips, Federal Highways Administration


This session will examine human factors issues associated with near-term deployment of ‘connected automation’ applications (lateral and longitudinal control) such as Cooperative Adaptive Cruise Control (CACC). Although already demonstrated as technically feasible, ‘connected automation’ applications face potential hurdles related to the abilities and limitations of the humans using them. Numerous human factors issues may impact the success of a connected automation application and need to be addressed before implementation. Use, reliance, and trust of automation have numerous pitfalls, all exacerbated when applied to the dynamic driving environments. Further, the effect connected automation applications usage may have on drivers’ workload directly impacts performance and safety and influences one’s overall situation awareness. The success of an application such as CACC also relies on an accurate understanding of general driving behavior (e.g., vehicle following, lane position variability, and lane changing). Each of these is influenced by a variety of both deliberate and reflexive human judgments, which are prone to errors and misguided decisions. Examples of near-term implementation questions and issues that could be explored include:

  • How will ‘connected automation’ applications be deployed in near-term to facilitate safe operations on freeways?
  • How will ‘connected automation’ applications vehicles interact with other ‘connected automation’ applications vehicles? With non-equipped vehicles?
  • How can the infrastructure support these interactions?

Proposed Session Agenda (assumption – afternoon deddion on Day 2)

1:30 PM Session Overview & Objectives (David Yang, Federal Highway Administration)
1:40 PM Human Factors Findings from a Connected Automation Application – Cooperative Adaptive Cruise Control (CACC)
  • Opportunities for Connected Automation Applications to Improve Mobility and Energy Use – Robert Ferlis, Federal Highway Administration
  • Findings from CACC Experiments: Overview and Merging – Brian Philips, Federal Highway Administration
  • Findings from CACC Experiments: Car Following and Collision Avoidance – Vaughan Inman, Leidos
  • Consolidated Q&A
[Note: Information presented in this portion of the Breakout Session will pave the way and serve as the “warm-up” for the remaining portions of this Session.]
2:30 PM Assignments for the Participants (Small Groups)
  • Session participants will be divided to small groups (6 people or less) and assign a relevant human factors issue related to ‘connected automation’
  • Specific instructions and expected outcomes will be given to each small group
[Note: Expert panel members from 3:30-4:30 PM portion of this Breakout Session will form their own small group to prepare responses.]
3:15 PM Break
3:45 PM Reporting Out from Group Assignments (Moderator: David Yang)
* Each small group will be given few minutes to report its key conclusions & recommendations from the assignment
4:15 PM Facilitated Expert Panel Discussion and Q&A (Facilitator: Don Fisher, Volpe National Transportation Systems Center)
Expert Panel Members:
  • Jessica Cicchino, Insurance Institute for Highway Safety
  • Charles Green, General Motors
  • John Lee, University of Wisconsin
  • Michael Regan, ARRB Group
  • James Sayer, University of Michigan Transportation Research Institute
  • Heishiro Toyoda, Toyota Technical Center
The facilitator will guide discussion between panel & session participants
5:00 PM Breakout Session Wrap-Up (Michael Manser, Texas Transportation Institute & Natasha Merat, University of Leeds)
5:30 PM Adjournment
