About the research


The Second Strategic Highway Research Program (SHRP2) Naturalistic Driving Study (NDS) data provides a unique opportunity to evaluate the relationship between driver and roadway characteristics in a manner not previously possible. These data provide a detailed record of driver and roadway characteristics during actual crashes/near-crashes as well as providing a snapshot of normal driving behavior.

This study will use the SHRP2 NDS and accompanying Roadway Information Database (RID) with a focus on speed and distraction from the perspective of the driver and roadway geometry and countermeasures from the perspective of the roadway.
