Implementation of Safety Prediction Methods Developed for Texas Highways

Texas Department of Transportation (TxDOT) Research Projects 0-7083 "Develop Highway Safety Manual (HSM) Safety Performance Functions (SPFs) and Calibration Factors for Texas" and 0-7067 "Enhancing Freeway Safety Prediction Models" developed safety prediction methods for all Texas highways. These methods are used to predict safety performance and help with the complex trade-offs between safety, operations, community impacts, and costs that are often necessary when planning and designing highway projects. These resources shall form a powerful tool for selecting Highway Safety Improvement Program projects and will support and defend safety decisions made by the Design Division and districts. The research team incorporated these methods into spreadsheet tools to implement the new models and facilitate analysis of all rural and urban roadway segments and intersections. The research team will develop and present webinars and workshops for TxDOT personnel who are responsible for traffic safety analysis. The webinars and workshops will familiarize personnel with the safety prediction methods and the analysis tools.
