Abstract:Safety has always been an important component in the planning, design, and operation of highways. In an effort ; to reduce crashes occurring on highway facilities, the Safe, Accountable, Flexible, and Efficient Transportation ; Equity Act - A Legacy for Users of 2005 established a new Highway Safety Improvement Program that ; encourages the integration of safety into the decision-making process and facilitates the expenditure of funds for ; highway safety improvement. A framework for highway safety mitigation is outlined in this report that provides ; a logical and comprehensive context within which efforts to improve highway safety can be made. This ; framework has been developed around the Roadway Safety Management Process contained in the Highway ; Safety Manual and has six primary steps: 1) Network Screening; 2) Diagnosis; 3) Countermeasure Selection; ; 4) Economic Appraisal; 5) Project Prioritization; and 6) Effectiveness Evaluation. ; The application of this framework and the predictive methods of safety analysis it entails requires ; familiarity with the latest advances in highway safety research and practices. Therefore, recommendations on ; safety workforce development are presented along with a summary of possible training resources. ; The framework for highway safety mitigation and safety workforce development recommendations ; provided in this report are part of an ongoing effort to improve highway safety across the state of Utah and will ; play an important role in training the next generation of safety experts that will be able to meet the highway ; safety needs of tomorrow.
