The Georgia Department of Transportation (GDOT) collects and maintains an inventory of all public roads within the state. The inventory is the most comprehensive source for assessing the official mileage, condition status, type, and use of all public roads in Georgia. Within GDOT, the inventory is an essential resource for reporting, analysis, and decision support and is the primary data source for completing the annual Highway Performance Monitoring System (HPMS) report for submission to the Federal Highway Administration (FHWA). Traditionally, field technicians have visually collected roadway characteristic while using pencil and paper recording methods. With more accessible Information Technology (IT), opportunities exist to improve operational efficiency, increase production, and enhance data quality. For the past two years, GDOT has sponsored Georgia Tech to develop GPS/GIS-based road inventory systems that reengineers the existing paper-pencil operations. This paper presents the development of the system, which incorporated various mature technologies, including Global Position System (GPS), Geographic Information System (GIS), Distance Measuring Instrument (DMI), and data management into the system to reengineer the current road inventory operations. The proposed system could significantly improve the productivity and the data quality for the field operation and expedite the analyzing and reporting processes. |
