3 Alexandria Statistics Located on the Western bank of the Potomac River Is the 7 th largest & highest income city in VA Has a population of 140,024 Part of Metro Washington DC area

4 Transmap/Timmons Partnership Transmap provided pavement/asset location information and condition assessment Azteca Cityworks is being implemented by Timmons Group to maintain these results from MicroPAVER The result of this project is a part of Alexandria s Comprehensive Transportation Master Plan

5 Overview ESRI MicroPAVER Alexandria Cityworks Transmap

6 Alexandria Street Network Alexandria has 275 miles of paved streets Cost to replace the road network would exceed 300 million dollars Current resurfacing budget is 2.5 million yearly.

7 Mobile Mapping Core High resolution cameras (1600x1200) Robust positioning (highest accuracy GPS/INS commercially available 1 to 2 foot) LiDAR (automated asset detection)

8 What are ON-SIGHT images? Real World GIS Van Location Layer Centerline Layer Smith St Main St Roadway Images in GIS

9 STEREO Images Explained 13 Foot Spacing

10 Raw Data to PCI First step is creating samples on the LRS

11

12 Pavement Distresses Alligator Cracking Pot Holes Block Cracking Rutting Linear Cracking Edge Cracking Patching/Utility Cut

13 Feature extraction software coupled with our ON-SIGHT HD images are used for pavement distress inspection Our experienced team visits each sample area and visually determines distress type, severity, and quantity to match APWA/ASTM industry standards.

14 Distress with Severity Medium Alligator Cracking Low Alligator Cracking Proper sealing lowers the severity of the distress

15 Distress with Severity Medium Block Cracking Low Block Cracking

16 MicroPAVER Pavement Condition Index (PCI) scores are calculated using MicroPAVER MicroPAVER bases the PCI calculation on Distress Type, Severity, and Quantity

17 Reasons for Pavement Management As pavements get older, condition and value decrease Typical maintenance treatments can be 5 to 40 times less expensive than total reconstruction Pavement life can be extended up to 10 years with maintenance treatments

18 Typical Degradation Curve

19 PCI Ratings Over Time

20 Linear Features Curbs Fences Guardrails Medians Number of Lanes One-Way Streets Road Width Sidewalks School Speed Zones Speed Limit Zones Pavement Striping

21 Linear Measurements Number of Lanes/Roadwidth

22 Point Features ADA Ramps Bridges Bus Features Control Cabinets Crosswalks Drainage Structures Driveway Aprons Hydrants Street Trees Water Valves Intersections Loop Detectors Manholes Parking Meters Pavement Markings Roadway Lighting Traffic/Pedestrian Signals Traffic Calming Devices Traffic Signs Signal Poles

23 Pilot Point Features Type: R2-1 Condition: Good Post Type: Wooden Pole Sign Face Direction: W Flashers: No

25 Capital Expenditures Assets that are maintained are capital assets Data created from this project will be used city-wide for many years

26 "Our pavement condition and inventory project will provide the city with an objective and systematic method for creating future paving plans." -L.A. McCracken Information Technology Coordinator Department of Transportation City of Alexandria, VA

27 Return on Investment Alexandria has over $300 million invested in pavement alone Using Transmap data, Alexandria is more efficient in allocating its budget With PCI Values ranging from Excellent to Failed, pavement improvement projects can be tailored to the more critical areas first

28 City of Alexandria Pavement Condition Index Ratings Public works has embraced the red, yellow, and green representation of pavement quality, as it helps identify the hot spots in Alexandria.

29 Alexandria PCI Values, 2008 Based on a total of 275 miles of roadway 66 miles of Fair to Failed roads

30 Planning Candidate Reports When will streets be repaired depending on the level of funding

31 Alexandria Phases Phase I Starting in 2008 with Total Pavement Collection Phases II Collected City wide Point and Linear data Phase III (????) Condition assessment of pavement will be updated to establish pavement curves

32 Transmap Best Practices Phase III will use the same network definition and sample model Inspection of the exact pavement samples previously recorded Results in more robust pavement condition analysis - previously sampled areas can be directly compared to newly sampled areas

33 Be Prepared to accurately account for your assets Document your needs Have all the facts Be compliant (GASB 34) How do my assets deteriorate over time? (pavement, signs) How can my crews be more efficient? Get shovels in the ground (people to work) Future Funding Shovel Ready!
