Abstract:
Winter storm events can have significant impacts on mobility and safety. During the past year, these impacts were investigated by the Center for Transportation Research and Education of the Iowa Department of Transportation. The documented project proceeded in two phases. First, data related to traffic flow, crashes, weather, and roadway conditions were collected from existing information management systems in Iowa; these data were evaluated and analyzed. Second, a mobile video data collection system was used to collect data during seven winter storm events. The results from both phases of this project are summarized.
