UPDATE ON FHWA SHRP2 AND STAC ACTIVITIES AND ENHANCEMENTS TO ROADWAY INFORMATION DATABASE (RID)

Abstract: This presentation will provide an overview of the Federal Highway Administration’s (FHWA) current Safety Training and Analysis Center (STAC) activities using SHRP2 data.  This will include a briefing of the status of the Implementation Assistance Program (IAP) projects and Broad Agency Announcement (BAA) projects that were conducted in cooperation with State DOTs and other research partners. Additionally, the presentation will describe the STAC efforts as a secure data enclave such as testing various protocols and tools.  The Roadway Information Database (RID) is subset of the SHRP2 Safety Data that provides roadway information collected on the majority of the roadway segments on which Naturalistic Driving Study (NDS) drivers drove for three years. The RID contains details on roadway variables collected through a mobile van, traffic and crash history data obtained from States and weather, work zones and 511 data obtained from each jurisdiction. This presentation will describe enhancement that FHWA completed to make the RID more user friendly:  1) Five reduced datasets have been developed that can be readily used for various highway safety projects; 2) A dynamic segmentation tool has been developed to easily merge several layers of data using ArcGIS; 3) Frequency tables describing the type and extent of mobile van data collected in the RID; 4)  Bubble charts developed by the FHWA Data Visualization Center for limited variables to represent the extent of the RID data; and 5) Five additional reduced datasets to be available later this year.
