Quantifying Drowsy Driving

Project Description This dataset was created to support a project intended to characterize the relationship between drowsy driving and crash risk in the SHRP 2 NDS, identify driver-critical reasons for crashes and near-misses in drowsy driving events, and identify individual differences including, but not limited to, demographics and personality characteristics, which correlate with the incidence of drowsy driving. Data Request Scope: This dataset contains: 2,048 trips extracted from the InSight query https://insight.shrp2nds.us/query/index#/builder?queryID=39023 A total of 785 trips which consisted of 585 crash/near-crash events previously coded as "Drowsy, sleepy, asleep, and fatigued" plus 200 baseline events without this impairment A subset of Insight-available variables and time series variables Video coding results. The video coding was performed at the VTTI data reduction laboratories to identify drowsiness based on whole body/face movements. Specifically, VTTI personnel coded Observer Rating of Drowsiness (ORD) ratings for 781 1-minute long trip segments of the SHRP 2 NDS. Data Specification This dataset contains different types of data from the SHRP 2 dataset: For the Event Detail Table variables, please see Insight_Westat_Dictionary.pdf For the time series variables please see TimeSeries_Dictionary.pdf and ProcessedRadarDictionary.pdf The forward video view (H.264 encoded MP4) The variables from the ORD coding are: SCE-BL_Event_ID: Event_ID of the crash, near crash, or baseline that was used in the SHRP2 Event Detail table (Insight). ORD_Event_ID: Event_ID of the 1-minute epoch created for the ORD ratings. These events start 1 minute prior to the precipitating event (when possible) and end at the precipitating event time. AVEORDRATING: Preliminary average of all current ORD ratings. NUMRATINGS: The number of preliminary ORD ratings that exist for each event. Event_Type : Designates each event as coming from the crash, near crash, balanced-sample baseline, or additional baseline pool. SampleSource: Designates each event as coming from the events previously flagged as Drowsy or Not Drowsy. AnonymousParticipantID: A numeric identifier assigned to a participant randomly during in-processing and used in place of any other driver identity information. Notes: Explanations for missing ORD ratings.
