1 ODOT Noise Barrier Inventory Application 2007 ADC40 Summer Meeting

2 Project Background Program Size and $$$ involved Physical Inventory and Assessment Various Suppliers and Manufacturers Wall ages vary Biennial FHWA Reports Maintenance Issues Longevity and Functionality Analysis The Great Wall of Gahanna Ohio s first noise wall in Ohio, built in 1975

3 The Project Development Business Case Time dedicated to queries from Public Legislators ODOT Management Municipalities Consultants Complaints Follow-up New Walls Planning and Status Legacy Data in people s heads and must be distributed School Administrators

4 Project Preparation EMH&T contracted to: Develop Data Model Develop Data Dictionary Perform Inventory Prepare Deliverable Format Create noise wall application to view results

5 Wall ID: Project Preparation: Data Model Built on location County Route Direction of travel Straight-line mileage Route type + Number + Direction + County + Straight-Line Mileage

6 Project Preparation: Data Model Physical Inventory: Start / End points Height / Length Panel Material Panel Texture / Color Post Material Typical front / back photographs

7 Project Preparation: Data Model Damage Assessment: Structural Panel / post damage Ground gap Aesthetic Weathering Peeling Paint / discoloring Dents / Cracks Damage Location Photographs

8 Field Work: GPS Start End Points GPS PDOP monitored Minimum number of positions Coordinates State Plane Latitude- Longitude

9 Field Work: Typical Wall Height Laser Rangefinder used to measure height Also used for difficult to access wall start/end points Accuracy ±0.5 at 200 yards GPS Location Offset Pt 1 Pt 2

10 Field Work: Typical Photographs 2 megapixel JPG format Typical wall front and back

11 Field Work: Overall Assessment Structural and Aesthetic Condition Percent of damage to entire structure General conditions: Ground gap, missing/damaged panels, fasteners Material-specific damage: Concrete spalling, cracking, efflorescence Steel peeling, rusting, denting Wood warping, weathering Fiberglass weathering, color

12 Field Work: Damage Points - Structural

13 Field Work: Damage Points - Aesthetic

14 As Delivered Noise Wall Database

15 As Delivered Damage Points Database

16 Hyperlinks Add fields to build directory structure Add individual Photo file names associated with each Noise Wall Start Point, End Point and Damage Point Populated Fields turned into HYPERLINKS. Example: O:\Environmental\Enviro\NOISEWALL Enviro\NOISEWALL PILOT TEST DATA FROM EMHT\PHOTOS\ODOT-NBI-A- ODOT-NBI 039.jpg

17 Hyper-linked Noise Wall Database

18 Hyper-linked Damage Point Database

19 Noise Wall Application With so much data and photos, ODOT needed a way to view, query and report on data Easy to use interface Minimal training and expertise

20 Noise Wall Application: Viewer

21 Noise Wall Application: Viewer Noise Barrier Damage Point Barrier Details

22 Noise Wall Application: Viewer

23 Noise Wall Application: Query

24 Noise Wall Application: Summary Report

25 Noise Wall Application: Detail Report

26 Noise Wall Application: Detail Report

27 Project Current Status Data Maintenance: Completing update of barriers constructed in Updating Noise Wall Database application: Inventory Queries Detail Reports Ad hoc Maps

28 Future Items: Desire to link existing ODOT noise wall data sets (e.g. manufacturer, install date) with other ODOT GIS data layers. Create an internet web portal as a complaint / query logging point Reduce amount of paper based complaints and the time required to respond. Develop distributed application for district use Develop noise barrier maintenance program

29 Future Items: Automate responses with personal form letters or s. Recover the time spent handling queries and complaints from Public Legislators School Administrators ODOT Management

30 Future Items: Utilize data and application as a major ODOT decision-making tool for Project Management Maintenance Scheduling Product Reliability Analysis Public Involvement Planning & Construction
