1. Development of GIS integrated Pavement Management System (PMS) for small cities. Golam Mohammad Moinuddin

2. Pavement Management System(PMS) Pavement Management System is a decision support tool that helps the agency personnel to maintain the road network more efficiently with less money. It looks into the road network, determines which section needs what treatment and determines which section needs to be worked first.

3. Outline Background Why use GIS. Development of the PMS Development Objectives Data Database Questions that will be answered. Need analysis. Use of GIS Future Goal Questions

4. Development Objectives Develop a PMS that –is built with widely available easy to use database. –can operate with limited available data. – employs relatively simple optimization procedure that can be explained to everybody. –show the applicability of GIS as a development platform.

5. Data The data used for this application is supplied by Texas Department of Transportation for the fiscal year of 2001. The dataset for the district of CORPUS CHRISTI is used for the application. Even TXDOT doesn’t have a complete datasets.

6. Data Limitation Partial inventory data is available. –Location with respect to Reference Marker. –Broad classification of pavement. –No structural data is available. Only partial distress data is available.

7. Database and GIS Software Microsoft Access database is used for application. Microsoft Access is used because its easily available and easy to use. Arc View GIS 3.1 is used as the GIS platform.

8. Questions that will be answered Which sections are the agency responsible for. Where they are located. What is the condition of the sections based on individual distress. Which sections needs what treatments. Cost of maintenance for different category. Priority list.

9. Need analysis Need analysis determines which section needs treatment and what treatment should be applied. Decision tree is used for the need analysis. Decision tree determines what treatment should be applied on a particular section based on distress condition.

11. Use of GIS Reference Marker Location –Since everything is located based on Reference Marker a map of reference marker will help easily identify locations.

12. Use of GIS Location of Maintenance sections. An interactive map which will help to locate a particular section or sections will aid the planners and maintenance personnel to plan scheduling.

13. Use of GIS Distress Condition of the Road Network Network Condition based on Block Cracking

14. Use of GIS Network Condition based on Failure Distress Condition of the Road Network

15. Use of GIS Network Condition based on Patching Distress Condition of the Road Network

16. Use of GIS Network Condition based on Longitudinal Cracking Distress Condition of the Road Network

17. Use of GIS Network Condition based on Transverse Cracking Distress Condition of the Road Network

18. Use of GIS Need analysis Network segments that needs to be removed and replaced

19. Use of GIS Network segments that needs to be overlayed Need analysis

20. Use of GIS Network segments that needs patching followed by seal coat Need analysis

21. Cost Estimation Cost of maintenance for each type of treatment will be calculated. The cost will be calculated for each type of road and for each county.

22. Future goal Prioritize segments.
