                Strategic Highway Research Program (SHRP2)
**Description:**
        The second Strategic Highway Research Program (SHRP2) focuses on applied research in four areas: safety, renewal, reliability, and capacity. The goal of the SHRP2 Safety Program is to address the role of driver performance and behavior in traffic safety. The related efforts and underlying data will provide a deeper understanding of driver behavior and how drivers interact with and adapt to their vehicles (including vehicle information systems), traffic, roadway characteristics, traffic control devices, and other environmental features. This effort resulted in two robust and linked databases: 1) naturalistic driving study (NDS) database, and 2) roadway inventory database (RID).
The NDS database includes detailed data on more than 5.8 million trips, 33 million travel miles, and 1.4 million driving hours from more than 3,100 participants of various ages across the country. The database represents continuous data from all trips taken by volunteer participants over one to two years. Instrumented vehicles were used to record vehicle location, forward radar, vehicle control positions, and video of the forward roadway and of the driver’s face and hands. Crash investigations were conducted after certain crashes to gather more detailed data. All future research efforts that seek to use the data collected in the SHRP 2 NDS database will require institutional review board (IRB) approval. In addition, researchers must establish a data-sharing agreement that guarantees privacy.
The RID contains new roadway data gathered by automated data collection vehicles and existing data provided by agencies (i.e., state DOTs, MPOs, and counties) in six states (Florida, Indiana, New York, North Carolina, Pennsylvania, and Washington). The new data contains approximately 12,500 centerline miles and the existing data contains more than 200,000 centerline miles. The roadway data includes roadway inventory information, crash histories, traffic, weather, roadway improvements, work zones, safety laws, and enforcement campaigns. The RID also provides a model for developing linked data sets for asset management purposes.
