56.3: Invited Paper: Exterior Displays for Autonomous Cars: Technologies, Icons, Evaluation.

Communication with other road users is very essential for autonomous as they might drive slower and the person on the driver's seat does not necessarily look on the street. To evaluate exterior displays, we build a full‐scale mock‐up with a RGB LEDs matrix display with 80 cm × 40 cm (128 × 64 pixel). Even text with a height of 10 cm was judged as readable from 50 m distance. Other results were the identification of signs with 40 cm height from 50 m. This is in accordance with common traffic sign standards. [ABSTRACT FROM AUTHOR]
