Srushti Rath’s MS thesis work on air taxis planning suggests access to airports as an initial market that can help drive investment. We developed a hub location model that is sensitive to mode choice between ground taxis and the air taxis. Findings suggest that 9 skyports would be adequate to serve such demand to accommodate variations in transfer times from ground taxi to the skyports. The research was partially supported by the C2SMART Center under USDOT grant #69A3551747124.
