Asset Management Tools

  1. 1. Asset Management Tools Sign, Pavement Management and Pavement Markings 2009 Iowa County Engineers Conference Zachary Hans, P.E. for Neal Hawkins, P.E. and Omar Smadi, Ph.D.
  2. 2. Sign Management
  3. 3. Maintaining Minimum Sign Retroreflectivity Revision 2 to the 2003 MUTCD FHWA adopted Jan 22, 2008
  4. 4. Compliance Dates • Jan 22, 2012 – jurisdiction shall use an assessment or management method to maintain sign retroreflectivity • Jan 22, 2015 – compliance with minimum retroreflectivity for regulatory, warning and ground mounted guide signs (except street name signs) • Jan 22, 2018 – compliance with minimum retroreflectivity for overhead guide signs and street name signs
  5. 5. Assessment or Management Methods • Visual Nighttime Inspection • Measured Sign Retroreflectivity • Expected Sign Life • Blanket Replacement • Control Signs • Other Methods
  6. 6. Sign Inventory
  7. 7. 1. Plug the GPS unit into a USB port. 2. Run the GPS Info program 3. Determine the COM Port number Select the “Scan Com Port” button and the software will identify the correct COM Location as part of port for you. Record the COM port which says software tool “GPS Receiver” which in this example is COM 5. Click “OK” to exit.
  8. 8. 4. To test if the GPS is working, click the “Start GPS” button. If the GPS is working, you will see scrolling text Select the “GPSInfo” button to see sattelite status Location as part of and GPS fix. After this, software tool please exit the program.
  9. 9. Database: LOCATION: POSTS: MANUFACTURING: Maintenance District: Post Size / Type: (post lengths are optional) Sign Information: 6 districts Wood Posts stock number (this entry can populate items below) Garage: 4" x 4" (lengths 10, 12, and 14 feet) sheeting 110 garages 4" x 6" (lengths 16, 18, 20, 22, and 24 feet) message System Class: Square Steel Tubing (all 12 feet long) size interstate 1.5" x 1.5" x 1/8" blank material iowa route 1" x 1" x 1/8" warranty information us route 2" x 2" x 1/8" Option: U-Shaped Delineator Posts implement bar code for all new signs Route Number: Type 1 (2 lbs/ft - Galvanized): lengths 8.5, 10, 12, and 14 feet other field signs collected manually all applicable routes Type 2 (1.12 lbs/ft - Galvanized): lengths 6.5 and 8.5 feet Ramp: Type 3 (1.12 lbs/ft - Painted): length 6.5 feet further choice would include "secondary" route I-beam Steel Breakaway Posts (from Std RD-21A-variable lengths) Longitude, Lattitude: W6x9, W6x12, W6x15, and W8x18 (all have a stub post length of 2.5 ft.) populate "X" and "Y" fields W8x21, W10x22, W10x26, and W12x26 (all have a stub post length of 3 ft.) Milepost: Other choose milepost based on route information above Utility Pole Offset: Truss / Cantilever identify offset to milepost (where longitudinally) Comment Number of Posts: POSITION: choose number Direction of Travel: Length of Posts: with milepost specify length against milepost feet only Side of Road: left SIGNS: right Date Installed: median date overhead Sign Direction: comment choose orientation… Lateral Offset (optional): Sign Condition: input distance rating system to be developed measured in feet only Daytime Check: date reflectivity (if taken) Nightime Check: date reflectivity (if taken) Ownership: dot along with DOT sign number other Inspector: initials or name Flag/Beacon/Etc.: yes, no or both
  10. 10. Management functions:
  11. 11. Quality Control • Identify Gaps/Missing Inventory Attribute-based Display of Sign Direction & Side of Road
  12. 12. Display of Sign Type or Sign Message Ex. Stop Signs
  13. 13. Display of Sign Type or Sign Message Ex. Curve, Chevron
  14. 14. Pavement Markings Goal: Provide an appropriate pavement marking on all highways, 365 days per year.
  15. 15. • What is Pavement Marking? – Material – Equipment – Installation – Operation A FACTORY on WHEELS (BIG or small)
  16. 16. Retroreflectivity – night time Presence – day time
  17. 17. Retroreflectivity and Presence Challenges
  18. 18. Wet reflective Challenges
  19. 19. Traffic
  20. 20. Road Maintenance Activities
  21. 21. $ 3.0/ft $ 0.03/ft Material Selection
  22. 22. Winter Maintenance Activities
  23. 23. Pavement Marking Management 2009 Smadi Hawkins
  24. 24. Measurement - Retroreflectivity • handheld • van
  25. 25. Paint Equipment • variety • tracking/recording • standards
  26. 26. Pavement Marking Data • General – Location (Route or GPS) • Retroreflectivity – Existing or New • Paint (binder) Application: – Initial Retroreflectivity – Type (beads and binder) – Install date – Quantities – Operations (Speed) – Weather
  27. 27. Pavement Marking Management INVENTORY •AADT •Miles PAVEMENT MARKING •Rural/Urban PAVEMENT •Condition •Age •Pvmt Type SAFETY •Location •Frequency •Type
  28. 28. PMMS Tool
  29. 29. Iowa PMMT (Spring 2008)
  30. 30. Iowa PMMT (Painted 2008)
  31. 31. Iowa PMMT (Fall 2008)
  32. 32. Pavement Management
  33. 33. Pavement Management in Iowa for Local Agencies
  34. 34. Why PMS? • Limited Resources • Staff Turnover • Consistent decisions • Structured / Objective process • Benefits (improved condition)
  35. 35. PMS Inputs/Tools • Condition Data • Database (Data Integration-GIS/GPS) • Performance Forecasting • Decision Support Tools
  36. 36. GOOD ???
  37. 37. BAD ???
  38. 38. GOOD or BAD ?
  39. 39. Automated Data Collection Tools
  40. 40. Pavement Condition Index (PCI) • A combined condition index: • Road roughness (bumpiness) • Rutting • Cracking (transverse, longitudinal, alligator) • Patching • Faulting • Calculated for Asphalt and Concrete roads separately • Scale of 0-100 with 100 being a new street
  41. 41. Pavement Condition Index (PCI) • PCI Scale: • Very Poor = PCI 0-20 • Poor = PCI 20-40 • Fair = PCI 40-60 • Good = PCI 60-80 • Excellent = PCI 80-100
  42. 42. Very Poor (PCI 0-20)
  43. 43. Poor (PCI 20-40)
  44. 44. Fair (PCI 40-60)
  45. 45. Good (PCI 60-80)
  46. 46. Excellent (PCI 80-100)
