After the TRB Annual Meeting in Washington D.C., Laura Fay (left), Karalyn Clouser (right), and Natalie Villwock-Witte traveled on to Maryland to meet with the Maryland Department of Transportation (DOT) about the Severe Weather Index (SWI) project. An SWI is a management tool that can assess the performance and related costs associated with winter maintenance operations. P.I. Laura Fay is leading the development of an SWI specifically for Maryland DOT, which assesses operations and costs by region, Maintenance Shop, and winter storm event.
