A challenge that many state DOTs face is the accurate assessment of winter maintenance operations. One tool that has been successfully used by DOTs is the severe weather index (SWI), which can assess the performance and related costs associated with winter maintenance operations. It considers the relative severity of each weather event, and relative severity of weather for that season.
Principal Investigator Laura Fay is leading a new project to develop a severe weather index for Maryland DOT by region, Maintenance Shop, and winter storm event. Maryland DOT can use the SWI to determine if costs incurred during each event and winter are reasonable, as well as if the resources deployed and contracted amounts are also within reason.

TR News magazine, published by the National Academy of Sciences’ Transportation Research Board, recently dedicated an entire issue to successful efforts to move research into practice. In the article “Going, Seeing, Showing, and Doing: Low-Tech Technology Transfer Works,” the authors highlighted WTI’s efforts to spearhead the National Winter Maintenance Peer Exchange from 2007 – 2015. Specifically, they note that attendees have “overwhelmingly cited the sharing of best practices and innovations as the most helpful part of the event.”
The article is included in the July/August issue of TR News, which was recently released online (see pages 38-43) or available For Download.
