Statewide Training of SafetyAnalyst in Florida

The objective of this project is to conduct: (1) a one-hour session on Engineering Statistics 101 for Safety at the 2015 Florida Department of Transportation (FDOT) Design Expo, and (2) a one-and-a-half day hands-on workshop on SafetyAnalyst. The research team will work closely with Dr. Sivaramakrishnan Srinivasan from the University of Florida (UF) in preparing and conducting both workshops. The specific work tasks are detailed below. Task 1: Prepare the Presentation for the 2015 FDOT Design Expo. The research team will prepare the presentation for the 2015 FDOT Design Expo. The presentation topic is Engineering Statistics 101 for Safety. This session aims to introduce the advanced methods in highway safety analysis. The traditional and the advanced methods, concepts, and terminology will be discussed. It specifically covers the following topics: 1. Why do people need to use the advanced tools – what is wrong with the traditional methods? a. Regression-to-the-mean (RTM) effect; b. Issues with crash frequencies and crash rates; c. Non-linear relationship between crashes and exposure (i.e., AADT); and d. Reactive versus proactive approaches. 2. Empirical Bayes (EB) Method. a. Safety Performance Functions (SPFs); b. Crash Modification Factors (CMFs) and Crash Reduction Factors (CRFs); c. Calibration Factors (C); d. Potential for Safety Improvement (PSI); e. EB-based before-and-after safety analysis; and f. Numerical Examples. Task 2: Present at the 2015 FDOT Design Expo. This one-hour session titled Engineering Statistics 101 for Safety will be presented on Thursday, June 11th from 9 AM – 10 AM during the 2015 FDOT Design Expo. It provides the background on the traditional and new highway safety analysis methods. This session primarily targets the general audience who are interested in understanding the big picture of the highway safety analysis. This session will serve as pre-requisite for the one-and-a-half day workshop to be conducted in Fall 2015. Task 3: Develop Material for the Hands-on Workshop on SafetyAnalyst. The research team will develop the workshop material on SafetyAnalyst applications. The following topics will be covered in the hands-on workshop: 1. Overview of the roadway safety management process; 2. Advanced EB method and concepts; 3. Introduction to SafetyAnalyst application; 4. Capabilities and limitations of SafetyAnalyst; 5. Detailed review of SafetyAnalyst modules; a. Network Screening; b. Diagnosis and Countermeasure Selection; c. Economic Appraisal and Priority Ranking; d. Countermeasure Evaluation; 6. Hands-on exercises using SafetyAnalyst; and 7. Understanding and interpretation of the output from SafetyAnalyst modules. Task 4: Conduct Hands-on Workshop. A one-and-a-half day hands-on workshop will be conducted in Orlando, FL in Fall 2015. About 20-30 participants from across Florida will attend the workshop. The participants will include engineers, planners, and designers from various FDOT district offices. At the end of the workshop, participants will be familiar with the EB method and the SafetyAnalyst application. Participants will be able to run the different modules in SafetyAnalyst, and correctly understand and interpret the output from SafetyAnalyst modules. At the end of the workshop, a certificate of training completion will be provided to each participant. Course evaluations will also be administered at the end of the workshop. Task 5: Prepare Draft and Final Reports. After conducting the workshop, a draft final report documenting all aspects of this project will be submitted to the STRIDE. The report will be well-written and edited for technical accuracy, grammar, clarity, organization, and format. The review comments will be addressed, and the final report will be submitted.
