Using a data-driven approach to analyze safety issues and projects will help Texas Department of Transportation (TxDOT) districts to target safety investments with more confidence and reduce crashes on Texas highways. Many predictive and systemic analysis tools are now available that provide the means to quantify safety impacts in a similar way so that roadway capacity and operations, environmental impacts, drainage, and pavement life can be quantified. The Texas A&M Transportation Institute developed a logical, practical, and data-driven framework for integrating these tools into practice within the TxDOT Beaumont District. There are four basic elements to consider when building a data-driven framework. The first element is the description of traffic safety issues. The second is the identification of roadway segments and intersections where the greatest potential to reduce crashes exists and the development and evaluation of potential safety treatments. This identification includes the assessment of historic crash trends combined with the application of new but proven safety analysis methods. The source of this information was TxDOT's Crash Record Information System, maintained by TxDOT's Traffic Operations Division. The third element is quantifying the correlation of prevalent crash types with specific roadway features to allow the development and evaluation of systemic safety improvements. The fourth element is the integration of safety assessment directly into the project development process or overall process from the conceptual to the construction phase. The purpose of this effort is to identify ways to better integrate safety assessment into identifying safety projects and to build more safety into new construction, reconstruction, and maintenance activities. The framework is intended to be a model that can be adapted and utilized in other TxDOT districts to assist decision makers as they determine viable roadway safety investments.
