Characterization of Blowover Risk in the Wyoming Highway System

The main goal of this study is to quantify the blowover crash risk associating with vehicle speed, load weight, wind field, and road geometry. One high-frequency wind monitoring tower will characterize the wind condition around the 2017 multiple rollover crash site (I-25 milepost 3-5), one of the known hotspots identified by Wyoming Department of Transportation (WYDOT) (2016). This field-observed wind speed data during gust events will improve the understanding of the rollover crash mechanism under adverse weather conditions. The field data and the high-resolution modeled data will be used to fill the gap between the Road Weather Information System (RWIS) and the rollover crash risk. The field-observed wind data will also be used for the rollover analysis for the prediction and prevention of such crashes in Wyoming.
