New instructional video: spreadsheet tool for flashing yellow arrows

A new instructional video guides practitioners through the use of a spreadsheet tool that can help determine when it’s safe to use flashing yellow arrows for permitted left turns.

Traffic engineers can use the spreadsheet tool to determine at which times of day crash risk is sufficiently low for flashing yellow arrows to be implemented safely at a specific intersection. The tool was developed as part of a project sponsored by the Minnesota Local Road Research Board and led by Gary Davis, a professor in the Department of Civil, Environmental, and Geo- Engineering at the U of M.

The instructional video is meant to help users understand the methodology behind the spreadsheet tool as well as how to use it. An instructor walks users through an example intersection, describes the inputs needed, and explains how to interpret the results.
