8. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 208 New Kent Guardrail Catalog Catalog of guardrails currently in place on routes: –30 –33 –60 –106 –155 –249 –273

9. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 209 Guardrail Catalog (cont.)

10. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 210 Preliminary Alteration of Catalog All routes put in one workbook –Worksheet for each route –Column labels aligned vertically to conserve space Experimentation using queries –Guardrails needing upgrades

11. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 211 Analysis of Catalog Data Data analysis for each route: –Total number of guardrails –Number of substandard guardrails –Percentage of substandard guardrails –Total length of guardrails –Number of each type of end treatment –Ultimately will be able to aggregate routes

12. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 212 Guardrails Needing Improvement

13. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 213 Improvements Needed For Different Routes

14. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 214 Addition of HTRIS Data HTRIS data added to a few locations for evaluation Graphs to compare accidents at different nodes
