About the research

CTRE will support the development and maintenance of the new Condition, Acquisition, and Reporting System (CARS) location module of CARS. CTRE will assist in creating the location database for CARS using Iowa DOT geographic information management system (GIMS) and linear referencing system (LRS) databases, based on CARS business rules. This will entail manipulating existing and derived data sets, including both spatial and attribute data, through use of geographic information system (GIS) software. This project will also identify and develop appropriate data creation automation procedures, develop quality control and assurance (QA/QC) procedures, and document the CARS location database creation work flow and QA/QC procedures.
