• Abstract:
  Existing driver distraction guidelines for visual-manual device interface operation specify traditional ; manual radio tuning as a reference task. This project evaluated the radio tuning reference task through two activities. ; The first activity consisted of a static evaluation of the features and layouts of 12 original equipment vehicle radios. The ; second activity consisted of an experiment in which naïve participants drove five models of vehicles on a test track ; while performing manual radio tuning tasks. Driving performance measures and eye glance behavior were examined ; during radio tuning and baseline (no secondary task) periods. Results showed differences between task and baseline ; periods in most measures as a function of radio design. ; Results of the test track radio running experiment were evaluated along with experimental data for radio tuning ; obtained in a driving simulator by NHTSA. Similar results were found for most eye glance measures. The data suggest ; the following visual demand acceptability criteria based upon driver 85th percentile radio tuning performance: ;  Individual eye glances away from the forward road scene should not exceed 1.3 seconds, and ;  Total eyes-off-road time to perform an entire task should not exceed 12.1 seconds. ; For compatibility with occlusion testing, these time values should be rounded off to multiples of 2.0 seconds. This ; gives task acceptability criteria of individual eye glances away from the forward road scene not exceeding 2.0 seconds ; and total eyes-off-road time to perform an entire task not exceeding 12.0 seconds.
