16-02: AWSSI Enhancements in Support of Winter Road Maintenance

Problem

State DOTs are always looking for ways to better prepare for winter storms/seasons but this is a difficult proposition as tools or software programs to provide this kind of information are not commonplace.

The Accumulated Winter Season Severity Index (AWSSI) is a simple and straight-forward tool that was developed by the Midwestern Regional Climate Center (MRCC) using non-proprietary data that is available from the National Oceanic and Atmospheric Administration (NOAA) for numerous locations within each state, nationwide.

This project seeks to modify this tool to make it more useful to state DOTs as they prepare for future winter storms/seasons.

Objective

To expand on the current AWSSI Tool to add more stations and provide features to allow for winter severity projections and connect winter severity to winter maintenance costs.

Expected Results

A simple tool that states can use to conduct their own calculations in order to relate storm severity to other factors, such as winter maintenance costs.
