This metric captures the financial commitments made towards transportation infrastructure initiatives that have successfully achieved financial closure and serve public interests. It specifically focuses on significant projects such as greenfield developments, comprehensive management contracts, and substantial operations agreements, while intentionally omitting smaller endeavors and asset divestitures. The investment comprises expenditures in new constructions and upgrades to existing facilities, alongside costs incurred for acquiring state assets or service rights. By articulating these commitments in current U.S. dollars, the analysis provides insights into trends and shifts in public-private collaboration in the transportation sector, highlighting the growing role of private investment in enhancing public infrastructure capabilities. The data is organized by the year of investment, offering a temporal perspective on funding flows.
