| Abstract: | This report presents findings from a research project that sought to provide a systemic framework to identify high-risk locations for roadway departure crashes and applicable countermeasures for implementation. The products of the research project are intended to assist Texas Department of Transportation (TxDOT) districts with selecting projects that address roadway departure crashes proactively (such as by improving guardrails and barriers, or by safety-treating roadside fixed objects) as opposed to reactively (by basing projects on crash history only). Additionally, this report provides updated work codes to assist TxDOT in better prioritizing projects, making a more optimal use of limited resources, and maximizing benefits derived from projects implemented as a result. For this effort, a select number of work codes were evaluated, and updates to their associated crash modification factors were developed based on available data on past Highway Safety Improvement Program projects in the state. |
