Safe-D: Safety through Disruption

Allusion 2: External Communication for SAE L4 Vehicles

Abstract

With the integration of SAE Level 4 or Highly Automated Vehicle’s (Level 4 Vehicle) into our environment, the development of external communication systems is underway by numerous stakeholders across the globe. Mixed fleets, comprised of both human drivers and automated vehicles, must be able to effectively communicate with each other. Most research on level 4 vehicle external communication has been conducted using simulator or virtual reality platforms to assess driver/road user knowledge, opinions, and attitudes via survey metrics evaluating a single level 4 vehicle. However, it is vital to understand how the external communication is perceived in real world conditions (e.g., bright sunny day, nighttime) and with multiple level 4 vehicles present.  Additionally, it will be important to understand other road users’ decision making based upon these external communication devices.  Thus, we are proposing to conduct research on the VTTI Smart Road Surface Street to assess pedestrian and driver decision making in the presence of level 4 vehicles with external communication displays.
