Federal regulations require states to have a multimodal long-range transportation plan that maintains at least a 20-year window into the future. The current SWTP has a “horizon year” of 2040. The SWTP assesses the current and future performance of all major transportation modes in the state and also examines the linkages between modes.
The SWTP also contains statewide economic and transportation demand forecasts for the horizon year of the plan.
The SWTP defines financially constrained and unconstrained statewide transportation programs estimate the programs’ costs, and forecasts available and potential funding. The SWTP provides GDOT with technical and programmatic guidance needed to meet the transportation demands of the state.
