Communication solution for safe and efficient autonomous vehicle-to-pedestrian interaction

Published: 9 October 2020

Researchers: Alexandros Rouchitsas and Håkan Alm

Interaction between drivers and pedestrians is often facilitated by informal communicative cues, like hand gestures, facial expressions, and eye contact. In the near future, however, when semi- and fully autonomous vehicles are introduced into the traffic system, drivers will gradually assume the role of mere passengers, who are casually engaged in non-driving-related activities and, therefore, unavailable to participate in traffic interaction. In this novel traffic environment, advanced communication interfaces will need to be developed that inform pedestrians of the current state and future behavior of an autonomous vehicle, in order to maximize safety and efficiency for all road users.

Human–machine interfaces that utilize the external surface and the immediate surroundings of the vehicle have been proposed as a possible solution to the communication problem road users will soon face in their attempts to interact with autonomous vehicles. The development of our external human-machine interface has now entered the evaluation phase. Preliminary results from empirical studies employing human participants confirm the effectiveness and efficiency of the proposed solution.
