The development of high-speed rail (HSR) in the United States has long been hindered by challenges related to market structures, government policies, and environmental factors. This research aims to explore and identify the most effective, sustainable, and equitable high-speed rail development frameworks applicable to promising U.S. corridors. By comparing successful international HSR systems—such as those in Europe, Asia, and Morocco—this study will evaluate how factors like network coverage, environmental impact, safety, and equity can be optimized within the U.S. context. Key questions addressed include determining which market structures best spur HSR development, how to ensure ticket affordability, and how to minimize environmental impacts while maximizing safety and usage.

To assess different international HSR models, a comprehensive rubric will be developed to weigh each market structure's economic, environmental, and political outcome against the current U.S. market's government and topographical conditions. The goal of this research is to provide policymakers with a framework to implement efficient, safe, and equitable high-speed rail projects that reduce the country's reliance on unsustainable road and air travel. This research is particularly relevant given the recent successes of Florida’s Brightline and the growing demand for sustainable short and medium-haul intercity transit. Through this analysis, the study aims to lay the foundation for a modern high-speed rail network that addresses economic and environmental concerns in the U.S. transportation landscape.
