Abstract

Safety hardware devices designed for use in roadways, such as barriers, breakaway signs, and crash cushions, undergo testing in accordance with national standards. Once devices are deployed on roadways, state departments of transportation (DOTs) evaluate collision and maintenance data to assess the performance of these devices in real-world conditions. Data can come from multiple sources, such as police and road maintenance crews, but currently neither the process nor the format for collecting these data is consistent, making broad analysis of road hardware less feasible. To address this need, Iowa DOT will study existing data collection methods with the goal of developing and communicating a uniform process for collecting data on safety hardware
