Stan Caldwell, executive director of Carnegie Mellon University’s Traffic21 Institute, said hyperloop could end up being an alternative to inter-city air travel, similar to the traditional rail system. That would be further helped by hyperloop stops closer to downtown than most airports, which are typically outside of downtown.

Hyperloop won’t necessarily replace existing modes of transportation though, according to Thea Walsh, director of transportation and infrastructure development at the Mid-Ohio Regional Planning Commission. The intention is to be more holistic, she said during a panel discussion on the technology at the Transportation Research Board’s (TRB) annual meeting in Washington, DC last month.
