Competitiveness of on-demand air taxis regarding door-to-door travel time: A race through Europe

We design and implement a door-to-door travel time estimation framework, which aims to analyze the potential competitiveness of on-demand air taxis in Europe when competing with existing transportation modes: car, railway and traditional air transportation. Our grid cell-based framework, opposed to previous studies, allows for fine-grained, high-resolution estimation of travel time lower-bounds between any points in the region of interest. Region-specific results on domination points and competition transitions of all modes are obtained and reported. Our work helps to understand the competitiveness of on-demand air taxis through the lens of door-to-door travel time estimation. keyword: On-demand air mobility; Competition range; Grid-based framework.
