OHS, UK - Accessibility of AADT Data on Local Roads

Abstract OHS, Improving Accessibility of AADT Data for Safety Analysis on Local Roads AADT is a critical input to safety performance analysis. However, due to limited traffic monitoring resources, AADT estimates are mostly available on state-maintained roads. Data on local roads are extremely sparse. A prior study has developed an approach to estimation of AADT on all roads, including local roads, in Kentucky. We propose to use the latest data from KYTC and third-party vendors to update the AADT estimates. We also propose integrating AADT with other highway attributes and crash records on local roads where safety performance analysis was previously limited due to lack of data. Goals and Objectives To update AADT estimates with latest data. To integrate AADT estimates with other highway attributes and crash records on local roads. Strategies and Activities The KTC team will first collect all pertinent datasets that are needed, such as updated HIS roadway geometry, usage, and speed data. The AADT estimates will be updated by re-training and re-validating of the model using the latest data. Link the updated AADT estimates for local roads with other highway attributes and crash records and analyze the sensitivity of safety performance with respect to volume and other factors.
