About the research
CTRE supported the development and maintenance of the new CARS-Location module of CARS (Condition Acquisition and Reporting System). CTRE assisted the Iowa DOT in creating the location database for CARS using Iowa DOT GIMS (Geographic Information Management System) roadway and LRS (linear reinforcing system) databases, based on CARS business rules. This entailed manipulating existing and derived data sets, including both spatial and attribute data, through use of GIS software. CTRE also identified and developed appropriate data creation automation procedures, developed quality control and assurance procedures (QA/QC), and documented the CARS location database creation work flow and QA/QC procedures.
