About the research

The Iowa DOT has requested research support in completing a state-of-practice survey and follow-up interviews with agencies that are installing multiple ITS sensors at roadway weather information system (RWIS) locations.

This project will support the overall objective of the Aurora Project through documenting existing state DOT and selective local agency practices where they have bundled multiple, non-intrusive traffic data collection sensors at RWIS collection sites. This documentation would include Aurora member states and other agencies with unique applications.
