Local Agency Traffic Count Incorporation for ITD Local Road Annual Average Daily Traffic (AADT) Estimates

This project will develop a process for incorporating local agency Annual Average Daily Traffic (AADT) counts into Idaho Transportation Department's (ITD’s) statewide traffic volume dataset. By integrating locally collected data, the project will improve the accuracy and credibility of AADT estimates across the highway system. The work includes creating a workflow for incorporating local counts and developing a schema within the ArcGIS Roads & Highways extension to manage AADTs. These efforts will ensure that local road estimates are properly calibrated to reflect real-world conditions while strengthening collaboration and data alignment between ITD and its local partners.
