Title:

Indiana Winter Severity Index

Abstract:

The Indiana DOT created the Winter Operations Team (WOT) committee to address issues associated with winter activities. Some of WOT's past activities have included developing its Total Storm Management Manual (TSM) and studying the effectiveness of several chemicals used by Indiana DOT. WOT determined that a winter severity index (WSI) would be helpful for several reasons. A subcommittee of the WOT was put together to study existing indices and to determine if one or a combination of indices could be used for Indiana DOT. The recommendation was that if other WSIs did not work, then an index for Indiana DOT should be developed. During development, the intent was to derive an index that did not require cumbersome and time-consuming data collection.
