Roadway Safety Analysis Methodology for Utah

This research focuses on the creation of a three-part Roadway Safety Analysis methodology that applies and automates the cumulative work of recently-completed roadway safety research. The first part is to prepare the roadway and crash data for analysis. The second part is to perform the network screening statistical analysis; rank the segments by state, Utah Department of Transportation (UDOT) Region, and county; and select segments of interest. The third part is to compile and publish the Roadway Safety Analysis reports for the selected segments of interest. These parts are accomplished using automation tools and graphical user interfaces. The Roadway Safety Analysis methodology allows future iterations of the Utah Crash Prediction Model (UCPM) and the Utah Crash Severity Model (UCSM) analysis and compilation of the Roadway Safety Analysis reports to be conducted in a user-friendly environment. A series of critical data columns were identified to communicate the need for data consistency for future iterations of this safety research. An example of the entire process of the Roadway Safety Analysis methodology is given to illustrate how the three parts tie together. The overall process has automated data processing tasks that save time and resources for the analyst to investigate possible safety measures for segments of interest. Recommendations for future highway safety research are given, including continued development of the Roadway Safety Analysis methodology, an analysis of intersections and horizontal curves, the implementation of the Roadway Safety Analysis methodology to other states, and the advancement of safety countermeasures and geospatial tools for highway safety research.
