25. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 25 Risk-Based Prioritization of Recovery

26. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 26 Features of Priority Setting Importance of roads and intersections based on critical facilities and condition of road network Restoring or replacing damaged equipment Critical facilities are those necessary for a community’s well-being

27. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 27 Classification of Critical Facilities

28. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 28 Critical Facilities

29. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 29 Geographic Information Systems Build on an existing GIS database of VDOT roads Network modeling used to create prioritization tool Using Microsoft Excel for optimization and user functionality

30. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 30 Electronic Road Map Two sources for electronic road maps VDOT’s “Network Level Basemap” –Used to establish road system from which network model will be created Census maps obtained from UVA Library –Used for geocoding addresses

31. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 31 Example of Arcview Map Suffolk District Hampton Roads Emporia Williamsburg Eastern Shore

32. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 32 Facility Data Acquisition Worked with the Hampton Roads Planning District Commission to get data on locations of critical facilities Facility data also collected by geocoding addresses in Arcview Critical facilities stored by category and sub-category

34. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 34 Data Summary Data gathered includes critical facilities, population, highway mileage, and connections Data is imported into Excel using a grid system Data is used to create a prioritization model in Excel

35. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 35 Excel Grid Method Microsoft Excel is used for the prioritization model A map is in the background of a spreadsheet for spatial reference In addition to being much easier for VDOT to use, the spreadsheet format makes modeling straightforward

36. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 36 Sample Excel Grid Method

37. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 37 Arcview Grid

38. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 38 Prioritization in Excel Spreadsheet layers contain facilities, road mileage, population, etc. Priority metrics are calculated across the grid Priorities are reflected by color-coding grid elements

39. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 39 Sample Categorical Prioritization

40. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 40 Decision Criteria The following types of data can be used for spreadsheet prioritization: –Population –Roadway mileage by road type (Interstate, US highway, or primary route) – three different measurements –Critical facilities by category (eight categories) All combinations are possible

41. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 41 Operating the Prioritization Tool All that is required is an entry of one or zero in each box of this table A one includes that category in the calculation This example does not break down the road types or the many categories of facilities

47. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 47 Temporal Priorities The model will prioritize recovery differently based on short, medium, and long-term goals Certain facilities are most important immediately after a disaster, and others are needed further down the road Since the Excel model includes data for all categories of facilities, roads, and population, these changes will be simple to implement

49. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 49 Decision Support for Resource Allocation

50. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 50 Motivation Hurricane Floyd struck Virginia in September 1999 and resulted in severe damage from flooding Over 100,000 phone calls to Emergency Operations Center as a result Large scale of disaster makes it difficult to appreciate where the resources are going

51. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 51 Objective To develop a methodology to support in decision-making for resource allocation and in communicating and substantiating its rationale for its decisions regarding resource allocation for highway recovery from a natural disaster.

52. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 52 Factors Impacting Resource Allocation Tool tests recovery projects against multiple objectives in order to offer an idea of priority of the projects Effective performance criteria needed –Risk reduction –Performance gain –Resources

53. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 53 Data Collection Case study performed using data from Hurricane Floyd recovery supplied by VDOT Data includes statistics from 39 counties/cities and 15 types of recovery/preparedness activity Data provided by Perry Cogburn, 2000.

64. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 64 Data Collection Interviews of Virginia agencies involved in the recovery process Specifically the situations in which they are depending or dependent on VDOT Currently conducting interviews of Florida agencies

65. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 65 Data Collection (cont.) Meeting with Susan Maddox Toth of VDOT’s EOC in Fall 2000 Liaison with VDEM in Fall 2000 who are making similar efforts Past report by UVa/VTRC regarding a specific delay

66. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 66 Outline of Interviews with DOTs and Agencies 1.What are the cases in which your agency waited on VDOT to be able to start a recovery activity? What are the cases in which VDOT was waiting on your agency? (For example, authorization, materials, personnel, etc.) 2.If not in the past, can you see your agency waiting on VDOT or VDOT waiting on your agency for a recovery activity in the future? Under what circumstances?

67. Center for Risk Management of Engineering Systems University of Virginia, Charlottesville 67 Outline of Interviews with DOTs and Agencies (cont.) 3.Is there anything VDOT could have done to better minimize the delay of recovery?
