Setting priorities: Georgia DOT assesses its state highway system and yields priority criteria
This article examines how state DOTs can achieve a working priority scheme for the maintenance of their highway and road infrastructure. It describes how the Georgia Department of Transportation (GDOT) balances its highway maintenance obligations through various transfers to local governments as well as other negotiations. Researchers in GDOT’s Office of Transportation Data (OTD) sought to develop a highway prioritization system by creating the criteria to determine which routes would have higher or lower priority. The OTD developed criteria by holding meetings with GDOT officials for input, determining what data was available, and examining the existing maps and data. They ultimately categorized state routes into four priority levels–Critical, High, Medium, and Low–each of which contains a number of road types (e.g. Critical state routes include interstates, intermodal connectors, and national/state freight corridors).
