Exploring Generalizability of Field Experiment Radio Tasks with Naturalistic Driving Data: A Comparison with SHRP2 NEST

In this study we compare glance patterns observed in field experiment driving studies with glance patterns observed in the naturalistic SHRP 2 NEST database. We describe the methodology used to identify appropriate naturalistic epochs and to prepare glances for comparison to field experiment data, and graphically show points of similarity and points of contrast between the two sets of data. Overall, glance patterns observed in field experiments appear to hold in naturalistic data, with a few caveats. Using naturalistic glance data to validate experimentally-acquired glance data appears to show promise and provides confidence for conclusions drawn from behaviors observed in controlled on-road driving scenarios.
