... The goals of the Safety Project S03 research were to • Prequalify commercial data collection vendors for bidding on Safety Project S04B, Mobile Data Collection; • Evaluate the precision and accuracy of the mobile roadway and pavement inventory data collection services as they relate to selected roadway safety data elements collected at highway speeds; and • Produce a recommended list of roadway data elements and associated specifications to be collected under the S04B project. On December 19, 2007, SHRP 2 awarded Safety Project S03 to the research team of Applied Research Associates, Inc.

... The evaluation of the initial data sets indicated that consistency of GPS data was very good for all sites, including various land use and cover conditions such as urban, rural, canopy, and highway locations. Five of the six data collection teams reporting GPS data achieved a consistency rating of sub-30 cm (1 ft)

... • Research revealed several potential challenges and opportunities related to integrating roadway element data and in-vehicle data to be collected in S07, In-Vehicle Driving Behavior Field Study. These were documented in a white paper, dated October 10, 2008, and resulted in splitting the S04 project into two components (S04A, Roadway Information Database Development and Technical Coordination and Quality Assurance of the Mobile Data Collection Project; and S04B, Mobile Data Collection)
