2 Introduction to GIS In Pavement Management Introduction to GIS In Pavement Management Alex Rocco and Barry Waite City of Carson Geographic Services Division

3 100 miles of street has a replacement value of approximately $42,000, miles * 5280 ft/mile x 36ft ~ 19,000,000ft 2 19,000,000ft 2 * 1 yd 2 / 9ft 2 ~ 2,100,000 yd 2 Average replacement value per yd 2 ~ $20.00 $20.00 / yd 2 * 2,000,000 yd 2 = $42,000,000 Good planning and preventative maintenance saves $$$. Is Management Important? Is Pavement Management Important?

4 Condition Time 40% Drop 75% Time 40% Drop 12% Time $1.00 spent here will cost $ $8.00 here Source: American Public Works Association Pavement Deterioration Curve

5 Pavement Deterioration Crop circles?

6 Tanks a lot! M1A1 Abrams Tank

7 Pavement Deterioration Not a trash truck

8 Pavement Deterioration Bradley Fighting Vehicle

9  Better visualization of current and expected conditions  Better analysis  Aggregate with other geographic features  Notify residents and businesses  Avoid shotgun approach  Better CIP planning  Reduce duplication of data  Traffic Accidents  Traffic Volume  Roads  Structural Data Why integrate GIS and Pavement Management? Why integrate GIS and Pavement Management? TM

10  Data Collection  Data Analysis  Reporting/Mapping Fundamental Elements of Pavement Management Systems Fundamental Elements of Pavement Management Systems

11  Relate the data to any geographic feature  Calculate pavement area for any geography  Overlay projects with other activities to avoid conflicts  Cluster projects AnalysisAnalysis TM

12  Avoid maintaining a street in 1998 and then an adjoining street in  Resurface and repair whole subdivisions  Simplify and reduce the cost of notifications Cluster Projects Clustering

13 CIPCIP Avoid maintaining a street in 1998 and then the storm drain under it in 1999.

14 CIPCIP Oops!

15  Functional Classification  Yearly Improvement Plans  Pavement Condition  Future Condition  Traffic Volumes MapsMaps TM

21  Priorities  Current conditions  Recommended corrective action  Long range plan ReportingReporting TM

22 Traffic Engineer Traffic Volumes Utilities Sewer Water Storm Maintenance Minor Repairs Engineering Major Improvements New Streets Materials Engineer Soils Avoid Redundant Data Collection

31 Geography is the Missing Link!!! Geography is the Missing Link!!!  Better visualization of current and expected conditions  Better analysis  Aggregate with other geographic features  Notify residents/businesses  Avoid shotgun approach  Better CIP planning  Reduce duplication of data Sound familiar?

32 Do as we say, not as we do  Make sure you or your consultant has a plan for integrating GIS and pavement management  Use a consultant who has GIS staff in-house  Collect other data while collecting street conditions  Signs  Signals  Manholes (personnel access covers)  Water valves  Catch basins  Visit other agencies who have been through this process  Do not allow tanks on your streets  Eat your vegetables

33 Let’s Go!
