Development of Improved Method for Determining Advisory Speeds on Horizontal Curves

The objective of this research study will be to create and validate a streamlined, field-based method to determine advisory speeds for horizontal curves. This research will help to develop and test an automatic and time-efficient process using electronic devices and software for identifying curve advisory speeds. The developed process can be validated against the results of a manual measurement process. It is anticipated that a more automated methodology will allow for efficient and accurate data collection. Accurate and efficiently-determined advisory speeds will assist Kentucky Transportation Cabinet (KYTC) personnel to properly sign horizontal curves resulting in a safer driver environment.
