    Coming In! : Communicating Lane Change Intent in Autonomous Vehicles
    Lee, Seonghee; Britten, Nicholas; Block, Avram; Pandya, Aryaman; Jung, Malte; Schmitt, Paul (ACM, 2023-03-13)
    Lane changes of autonomous vehicles (AV) should not only succeed in making the maneuver but also provide a positive interaction experience for other drivers. As lane changes involve complex interactions, identification of a set of behaviors for autonomous vehicle lane change communication can be difficult to define. This study investigates different movements communicating AV lane change intent in order to identify which effectively communicates and positively affects other drivers’ decisions. We utilized a virtual reality environment wherein 14 participants were each placed in the driver’s seat of a car and experienced four different AV lane change signals. Our findings suggest that expressive lane change behaviors such as lateral movement have high levels of legibility at the cost of high perceived aggressiveness. We propose further investigation into how balancing key parameters of lateral movement can balance in legibility and aggressiveness that provide the best AV interaction experience for human drivers.

    Safe to Approach: Insights on Autonomous Vehicle Interaction Protocols with First Responders
    Lee, Seong Hee; Patil, Vaidehi; Britten, Nicholas; Block, Avarm; Pandya, Aryaman; Jung, Malte; Schmitt, Paul (ACM, 2023-03-13)
    As autonomous vehicles (AV) become increasingly common on our roads, it is important for first responders - police officers, firefighters, and emergency medical services to learn new interaction protocols as they can no longer rely on those applied to human-driven vehicles. This study identifies critical pain points and concerns of first responders interacting with AVs on the road. We explore 7 different designs that communicate that an AV is in park and is safe to approach and analyze how first responders perceive these designs in terms of clarity and safety. We conducted qualitative interviews with 9 first responders and gained insights on how the needs of first responders can be integrated within the AV design process. As a result, we identify an AV safe park state communication protocol that would be ideal for first responders. Additionally, we derive a guideline for effective communication methods that can be used in the design of these vehicles establishing research methods that involve emergency responders within the loop.
