Enhancement of Pavement Maintenance Management Using GIS
YiChang (James) TsaiJames L. Lai , Lixiang Sun
In pavement maintenance management, it is beneficial for engineers and planners to spatially visualize and analyze pavement maintenance information so that the pavement maintenance resources can be allocated reasonably. The pavement maintenance information includes pavement condition rating, distress distribution and the required rehabilitation. GIS provides an excellent spatial query and analysis capability. With these capabilities, the pavement maintenance management can be greatly enhanced. This study uses Esri software, Arcview GIS to analyze the pavement condition survey data provided by Georgia Department of Transportation (GDOT) for Gordon Country, Georgia. This study focuses not only on the application of GIS on pavement maintenance management but also on how to transform data from different data formats into the GIS environment. An assumption about segment rating mainly caused by load cracking was made. Hypothetical data about associated rehabilitation methods and costs were also used to demonstrate the full functionality that can be provided through using GIS. Two visualization alternatives upon levels of detail about information are presented in this paper. One is route-level, based on line, and the other is county-level, based on polygon. The spatial distribution about the pavement rating can be displayed and subsequently the associated rehabilitation methods and costs can then be analyzed.
