1 Enhanced Pavement Management Program Presented to the Transportation and Environment Committee Feb. 12, 2007 VISION STATEMENT Creating the Most Cost Effective, Pavement Management Program in the Nation 1

2 OUTLINE: Background of the Program Investigate Best Practices Recommend a Solution Schedule of Results 2

3 BACKGROUND: Means and Methods were Typical From 1982 to 2005 For the past 30 years, Dallas has inventoried street conditions using manual methods (paper and pencil) and stored the data on the mainframe We are now positioned to take advantage of significant technological developments The Program has been in transition since FY 04/05 and is evolving into a next generation Pavement Management System We are proposing to adopt semi-automated data collection devices and GIS-based software that will provide near-real real time data access 3

4 BACKGROUND: The Period of Transition between FY 04/05 and FY 06/07 have seen significant changes 14 $900, Reduced 54% 04/05 PSI 05/06 Transition 06/07 PMP STAFF Reduced 62% 04/05 PSI 05/06 Transition 06/07 PMP VEHICLES $800,000 $700,000 $600,000 $500,000 $400,000 $300,000 $200,000 $100,000 $0 $770,000 $560,000 Reduced 37% ($288,000) 04/05 Past 05/06 Transition 06/07 Enhanced BUDGETS $482,000 4

5 INVESTIGATE: We Compared the Past with Best Practice Concepts: Manual / Automatic Methods Subjective / Objective Data Complex Processing / Simple Operation Annual Data Summaries / Near-real real-time Data available Updates 5

6 INVESTIGATE: Good examples of success were found at 6 Index Cities, Major Cities as well as 9 other leading agencies Case Studies: Revealed 4 Desired Capabilities 1. Pavement Performance Modeling 2. Automated Data Collection 3. Data Cleanup and Integration to GIS 4. Flexibility to inventory other roadside objects Best Practice Program costs are comprised of: 68% Data Collection 22% Analysis 10% Administration They all Emphasized need for Trustworthy Data 6

7 INVESTIGATE: DATA COLLECTION PAST Windshield Inventory Paper and Clip Board Inventory Single Data Collector per Vehicle, Stop and Go Inspections BEST PRACTICES Automated Data Collection PC Tablet with Multiple Road Sensors 2-33 Person Crew in a Single Vehicle Continuous Data Collection 7

8 RECOMMEND: How to Maximize the Benefits of the City s s Investment in Road Repairs and Replacement? Only Collect What You Need: Which Distresses Trigger Which Repairs? How Much do Repair Strategies improve Street Life? When is the Critical Time to Repair Roads? Where are Repairs Working the Best or Worst? What Projects are Critical to Achieving Objectives? 8

9 RECOMMEND: Several issues involved in the enhancement will be more attainable when implemented in a phased approach: Acquire Street and Alley Inventory Vehicles Implement New Equipment, New Software and New Procedures, Train Staff Validate Trustworthiness of Inventory Data Consider opportunities to support delivery of other City services (Airport, Signs etc) Acquire Structural Analysis Equipment Optimize Pavement Performance Analysis 9

10 RECOMMEND: The Data Collection Vehicles will Inventory Objects and Measure Pavement Distresses Along Roadways LOCATION INVENTORY DATA MEASURE DISTRESS VIDEO IMAGES NOTE: There is also an Alley Inventory Vehicle that will utilize e an existing city vehicle to collect simple data for the analysis of Alley conditionsc 10

11 RECOMMEND: Pavement Management Software will Expedite the Access and Analysis of Street and Alley Data 11

12 RECOMMEND: Objective Distress Measurements Adopt Automated Surface/Sub-Surface Data Collection Clarify Maintenance Strategies/Optimize Budgets Performance Forecasting GIS Develop Modeling, Life Cycle Costing, Budget Impacts, Economic Analysis, Long Term Planning Forecasts Cultivate the Wise Use of Data to Improve Road Life Use Mapping to Communicate Conditions and Planning Provide Easy Mapping of Proposed Projects and Results Validate and ensure All Data is Trustworthy Model Needs for Future Capital Programs Encourage What If Budget Scenarios Flexibility to Expand into Multi-Department Support 12

13 RESULTS: A. CONTINUE WITH PAST METHODS Cost of City Service with Existing Equipment $442,000 5,800 LM (50% 50% the Streets and no Alleys annually) B. ADOPT BEST PRACTICES Cost of City Service with New Equipment* ($482,000 + $140,000) 11,600 LM *( *(Equipment Amortized/ 4 years + 100% Streets and 33% Alleys annually) C. OUTSOURCE Cost of Professional Service Fees Ranged from $100 -$200/Ln Mi x 11,600LM (Equipment Imbedded in Fee, 100% Streets and No Alleys) $ 442,000 $ 76 /Ln/ Mile $ 622,000 $ 54 /Ln/ Mile $ 1,160,000 $ 100 /Ln/ Mile 13

15 RESULTS: BETTER DATA IN 2007 Improve the Support and Development of Future Street Maintenance and Capital Bond Programs 1) Ensure roads receive appropriate repairs and will last longer 2) Require improvements in the accuracy and truth of condition ratings 3) Enhance ability to optimize road repair decisions 15
