Investigating HMIs to Foster Communications between Conventional Vehicles and Autonomous Vehicles in Intersections

Understand

In mixed traffic environments that involve conventional vehicles (CVs) and autonomous vehicles (AVs), it is crucial for CV drivers to maintain an appropriate level of situation awareness to ensure safe and efficient interactions with AVs.

• This study investigates how AV communication through human-machine interfaces (HMIs) affects CV drivers' situation awareness (SA) in mixed traffic environments, especially at intersections.
• Initially, we designed eight HMI concepts through a human-centered design process.
• The two highest-rated concepts were selected for implementation as external and internal HMIs (eHMIs and iHMIs).
