Clear Roads: Accumulated Winter Season Severity Index (AWSSI) Enhancements in Support of Winter Road Maintenance

Status:  Complete
Project Start Date:  04/17/2018


The Accumulated Winter Season Severity Index (AWSSI) is a simple and straight-forward tool that was developed by the University using non-proprietary data that is available from the National Oceanic and Atmospheric Administration (NOAA) for numerous locations within each state, nationwide. This is a general index for winter severity. University will develop additional visual data representation tools that will allow State to compare the current winter with past winter, allow State to view a likely range of projections for the current winter based on past winters and to expand the number of locations for which the AWSSI is calculated. In addition, University will investigate the feasibility of a modified AWSSI for snow and ice control that will provide a better correlation to winter maintenance costs and implement the modified index.
