| dc.description.abstract | The Second Strategic Highway Research Program (SHRP 2) Naturalistic Driving Study (NDS) data set contains approximately 5.51 million naturalistic driving trip files across thousands of consented drivers, making it the largest data set of its kind. Before these data can be used to answer research questions, we need to ensure that only consented driver data will be used and that non-consented data are removed from the database. Virginia Tech Transportation Institute (VTTI) research staff performed a Rapid Driver Identification (RDI) task to identify trip files with and without consented drivers. An initial driver recognition step was performed on a small sample of files from each vehicle, followed by a review of the full data set using a recently developed rapid assessment tool that permitted files to be reviewed approximately 25 times faster than before. In all, 6.48 million files were coded, of which 5.51 million are associated with a consented driver during a consented time period. These files represent 3,353 vehicles and 3,546 unique participants, of which 3,241 were primary drivers and 305 were secondary drivers. The products of this task will serve future researchers using the SHRP 2 NDS website for years to come, as well as provide tools and expertise for the rapid assessment of Driver ID in future large-scale naturalistic driving studies. | en |
