dc.description.abstract Passenger car cabin videos obtained in a previous naturalistic driving study of part-time belt users were coded to characterize front-seat passenger attributes and behaviors. Among the 959 passenger trips, the median trip duration was 10 minutes; the 95th percentile was 52 minutes. Frames from the beginning, middle, and end of trips longer than 5 minutes in duration were extracted for coding, along with a middle frame from trips shorter than five minutes. Front-seat passenger characteristics, postures, and activities were coded in a total 2438 frames. In approximately 72% of frames coded, the passenger was male and 77% of the passengers were estimated to be less than 30 years of age. In 33% of frames, the passenger did not wear the seatbelt. The most common passenger activity was talking (57%); phone interactions were observed in 10% of frames. Passengers were most often looking out the windshield (57%), followed by facing the passenger window (17%), their lap (14%), or the driver (10%). The passenger’s torso was rotated away from a neutral posture in more than 25% of frames, including pitched forward (17%), rotated left (6%), or rotated right (4%). The seat back was recorded as reclined beyond normal in 13% of frames, but very reclined in only 1.3% of frames. en_US
