10 Requirements Summary Definition of requirements and user needs of the MiniFaros laser scanner from vehicle advanced driver assistance system, ADAS, point of view. Accident review and state-of-the-art ADAS surveys shows that there is a big potential for the MiniFaros laser scanner to be used as environment perception sensor for such applications. About two third of serious accidents (54-74%, 64-82%) can be addressed by a laser scanner with the following requirements Range m Field of view 250 deg Update frequency 25 Hz Range accuracy 0.1 m Angular accuracy 0.25 deg MiniFaros - ITS world congress, Vienna 10
