Evaluating the Relationship between the Driver and Roadway to Address Rural Intersection Safety using the SHRP 2 Naturalistic Driving Study Data

Project Description This project observed driver behavior at rural intersection in order to better understand where drivers focus their attention, the role of distraction, the effectiveness of current countermeasures, roadway factors that lead to driver errors, and the impact of environmental factors on driver error. Data Request Scope All available driver and time series data for each intersection was requested. Data Specification Driver Survey Variables Driver age Gender Education level Annual miles driven Years of driving Number of moving violations Number of crashes DAS Variables ABS activation Acceleration, x-axis Acceleration, x-axis fast Acceleration, y-axis Acceleration, y-axis fast Acceleration, z-axis Acceleration, z-axis fast Airbag, driver Alcohol Cruise control Date (as described by VTTI this will include a measure of time of day, month, and year which is provided in a format so that it does reveal personally identifying information) Dilution of precision, position Time into trip (an approximate measure is acceptable if this is considered identifying, i.e. we would like something like 15 to 20 minutes from start of trip) Driver button flag Electronic stability control Elevation, GPS Head confidence Head position x Head position x baseline Head position y Head position y baseline Head position z Head position z baseline Headlight setting Illuminance, ambient Lane marking, distance, left Lane marking, distance, right Lane marking, probability, right Lane marking, type, left Lane marking, type, right Lane markings, probability, left Lane position offset Lane width Latitude Longitude Number of satellites Pedal, accelerator position Pedal, brake Pitch rate, y-axis Pitch rate, y-axis fast PRNDL Radar range rate forward x track n Radar range rate forward y track n Radar, target identification Roll rate, x-axis Roll rate, x-axis fast Seatbelt, driver Speed, GPS Speed, vehicle network Steering wheel position Timestamp Traction control Turn signal Video frame
