ABSTRACT
A Geographic Information System (GIS) is a powerful tool to manage and analyze data referenced to a geographic location. A GIS-Pavement Management System (GIS-PMS) integrates tabular data and geographic features being able to retrieve the information rapidly and effectively.
The major advantage of a GIS-PMS is in serving as an analytical tool to perform queries and visualize the results in theme maps.
METHODOLOGY
1. Integrate data gathered from different sources
Show street network data in theme maps
3. Identify treatment and budget needs
4. Analyze the impact of Maintenance and Rehabilitation strategies
5. Visualize the impact of Maintenance and Rehabilitation strategies on “what if” theme maps
6. Explore new approaches to visualize the data using GIS capabilities
Budget Needs over a 20 Year Period
Minimum PCI Grid Theme
CONCLUSIONS
The possibility to integrate a Pavement Management System with other infraestructure management systems using GIS as the heart of a central database is feasible.
A global system based on GIS technology will allow agencies to share, and compare information among databases, avoiding project conflicts, and making more coherent decisions.
