Disconnects in Megaregional Freight Planning Are Holding Back the Louisiana Gulf Coast

The megaregion has emerged as the preferred unit of analysis for freight transportation and global trade. In the United States, trade and transportation barriers of state boundaries can impede the formation of megaregions, resulting in the hampering of economic development. As a preliminary investigation of the Gulf Coast megaregion, we performed a content analysis of the relationship between freight-related themes in the comprehensive and long-range plans for the metropolitan areas and the respective 11 parishes (counties) in southeastern Louisiana. Our results indicated a slight correlation between freight transportation infrastructure resources and theme frequencies in the histograms, but an overall lack of planning focus on freight infrastructure or trade capacities throughout the study area. Although freight transportation is becoming important federally, Louisiana state and local governments do not fully plan for it, leading to outdated transportation systems, inefficiency, and congestion
