Implementation of Automatic Sign Inventory and Pavement Condition Evaluation on Georgia's Interstate Highways

Traffic signs and pavements are indispensable assets to facilitate safe and uninterrupted travel. Manual methods are used for both traffic sign inventory and pavement condition evaluation by the Georgia Department of Transportation (GDOT), although they take excessive time, consume great amounts of labor, and sometimes expose field engineers to roadway hazards. GDOT still lacks a complete traffic sign inventory for its interstate highway system. For pavement condition evaluation, although the current Pavement Condition Evaluation System (PACES) performs well on non-interstate roadways, it is challenging to survey interstate highways due to limited parking space and safety concern caused by high-speed, high-volume traffic. To leverage the automated methods developed through its national demonstration project, the Georgia Tech research team surveyed more than 2,500-survey-mile interstate highways in Georgia and established a complete traffic sign inventory and Computerized PACES (COPSACE) database using the newly proposed streamlined procedures. The successful implementation has demonstrated that the streamlined procedures provide a consistent, reliable, and cost-effective means for traffic sign inventory and pavement condition evaluation.
