The goal of road asset management is to enable more effective resource allocation and utilization via quality informa¬tion and analyses, and to address infrastructure maintenance, operation, and improvement issues. Visualization of road condition data and road inventory data is important to achieve these goals. Due to this reason, more and more road controlling agencies have adopted geographical information system (GIS) as a useful tool for data visualization and integration. However, most of commercial-off-the-shelf (COTS) GIS software such as ArcGIS and MapInfo are expensive and require GIS specialists to operate and maintain them, which make it difficult to share the information in them by personnel working in different organizations. As a geographic browser, Google Earth (GE) provides a free, easy and fast and robust environment for users to explore the entire earth and to share annotations by using the keyhole markup language (KML). In this presentation, method and examples for applications of GE to visualize road condition data and inventory data through KML will be presented. The road condition data (either in network level or project level) can be shown in GE includes data collected from high speed data collection equipment (IRI, rutting, texture, skid resistance and geometry) and data from low speed equipment like FWD. The road inventory data can be shown in GE includes road maintenance works, road accident data and road images/video etc. Possibilities of road asset data integration through GE will also be discussed.
