A sustainable multi-objective framework for multi-phased, capacitated vertiport siting with land use integration

open access: yesCommunications in Transportation Research
This research presents a multi-objective optimization framework for incremental siting of capacitated vertiports that integrates real land use data and aims to maximize generalized cost savings while minimizing infrastructure costs and emissions.
