MIT has a Master of Science in Transportation (MST).
Overview of the MST
The Master of Science in Transportation (MST) degree program examines all major forms of transportation, including passenger and freight systems, and the increasing demand for these systems at the local, regional, and international level. In a few years, more than six billion people will inhabit the world, placing enormous stress on existing air, rail, and highway transportation systems and creating the need for new ways to plan, manage, and engineer the systems of the future.
Seems like it would be right up your alley.
