| 摘要： | Safety and Mobility Impacts of Winter Weather - Phase 1 investigated opportunities for improving traffic safety on state-maintained roads in Iowa during winter weather conditions. The primary objective was to develop several preliminary means for the Iowa Department of Transportation (DOT) to identify locations of possible interest systematically with respect to winter weather???related safety performance based on crash history. Specifically, four metrics were developed to assist in identifying possible habitual winter weather-related crash sites on state-maintained rural highways in Iowa. In addition, the current state of practice, for both domestic and international highway agency practices, regarding integration of traffic safety- and mobility-related data into winter maintenance activities and performance measures was investigated. In Phase 2, a combination of the Phase 1 results and Iowa DOT maintenance field staff input were employed to evaluate three Iowa DOT high-priority sites. Winter-weather crash-mitigation analysis procedures were developed and applied for three sites. Realistic maintenance and operations mitigation strategies were also identified. |
