An interim report of the study was discussed Wednesday by the State Transportation Board.
The consultants conducting the study, Cambridge Systematics Inc., conferred with shippers and railroads to come up with a map of likely choke points as freight traffic increases.
The report identifies Interstate 75 between Macon and Atlanta and I-85 between Atlanta and the South Carolina line as prone to serious clogs.
Rail problems include stretches with single tracks that allow trains to pass each other only at limited sidings.
Page Siplon, executive director of the Center of Innovation for Logistics, says a goal of the study is to convince developers to invest in Georgia's infrastructure.
