1. Advantages and Disadvantages of Using Automated Data Collection in the Pavement Management System Prepared by George Alsayegh
2. Outline Introduction
Pavement Management System Cycle
Data available for collection
Automation in data collection
Advantages and Disadvantages
Ministry of Transport, Alberta PMS
Pavement Management: finding a cost-effective combination of treatments to apply at any given time to give the desired level of service
Pavement Management System: decision support tool that is designed to be used to help make cost-effective decisions concerning the maintenance and rehabilitation of pavements and road surfaces
4. Pavement Management System
5. Data Collection Types of Data to be Collected:
Performance i.e. Distresses, Deflection, Roughness, Fiction...
Historic i.e. Traffic, Accidents, Maintenance...
Geometry i.e. Dimensions, Grade, Shoulders/Curbs...
Costs i.e. Construction, Maintenance, User, Rehabilitation
Policy related i.e. Budgets, Strategies
Environmental i.e. Drainage, Climate
6. Automation in Data Collection Various devices used including the following:
7. Digital Incremental Profiler (Dipstick)
8. PURD Trailer
9. Automatic Road Analyzer (ARAN)
10. Vehicles Counters and Weights in Motion
11. Automatic Vs Manual
12. Disadvantagesand Advantagesof Automated Data collection
13. Disadvantages of Automated Data Collection in Pavement Inaccuracy:
oil residue, dirt, lane markings, vehicle's tire mark, tree limbs, and other non-distress related items
Bad quality reading
14. Disadvantages of Automated Data Collection in Pavement Some variable are unquantifiable
Strategies and decision making
15. Disadvantages of Automated Data Collection in Pavement Require proper data management and data Integration
16. Disadvantages of Automated Data Collection in Pavement Higher cost if technology not owned
17. Disadvantages of Automated Data Collection in Pavement Compatibility of newer Systems
Old System Vs New System
Human A Vs Human B
18. Advantages of Automated Data Collection in Pavement Faster analysis of data
19. Advantages of Automated Data Collection in Pavement Better view of pavement condition using GIS
20. Advantages of Automated Data Collection in Pavement Reduced manpower
Transfer of analysis from site to office
21. Advantages of Automated Data Collection in Pavement Safer environment
22. Advantages of Automated Data Collection in Pavement Standardised data collection
23. Alberta Example
25. Alberta Pavement 2008 Pavement
26. Ministry of transportation, Alberta Subcontract the work to EBA Engineering Consultants Ltd.
EBA Engineering Consultants Ltd uses:
high-speed inertial profilers
Falling Weight Deflectometer (FWD)
Heavy Weight Deflectometer (HWD)
measure the condition and performance of transportation infrastructure including roads, bridge decks, runways and taxiways, ice roads, and railroads.
27. Opinion Although there are some of the disadvantages but it is could be ignored because:
PMS is not yet sophisticated data to involve data integration
Network level PMS requires less accuracy than Project level
Upgrading systems is expected after 5-10 years
Big districts must use Automated Data Collection systems for their PMS
