Analyzing Driver Behavior Using Data from the SHRP 2 Naturalistic Driving Study. A SHRP 2 Safety Project Brief.

摘要

Studies have long shown that the most significant factor in crashes is the driver. To date, however, the driver and the drivers interaction with the road, vehicle, and environment have been difficult to study in an objective way. A new method, naturalistic driving studies (NDS), provides objective data, which transportation agencies can use to derive improved countermeasures and more effective uses of existing countermeasures to reduce crashes and improve roadway safety. The second Strategic Highway Research Program (SHRP 2) is conducting the largest and most comprehensive NDS ever undertaken. The study has recruited more than 3,100 volunteer drivers, ages 1680, at sites in six states: Florida, Indiana, North Carolina, New York, Pennsylvania, and Washington. All their trips are recorded for up to two years. Data include vehicle speed, acceleration, and braking; vehicle controls; lane position; forward radar; and video views to the front and rear of the vehicle and on the drivers face and hands. When complete in early 2014, the NDS data set will contain in excess of 33,000,000 travel miles from some 3,800 vehicle-years of drivingmore than 4 petabytes of data.
