Road disruptions due to disasters can result in low accessibility or isolation of disaster sites. To solve this, we propose to utilize eVTOL (electric vertical take-off and landing) aircrafts to expand air transportation network for better and efficient humanitarian activities. Specifically, we propose to locate emergency ports for eVTOL strategically considering road network vulnerability. A mixed integer programming (MIP) model is formulated to select a suitable location of emergency ports for eVTOL considering road network disruption scenarios caused by disasters. The objective is to minimize the cost of transporting the relief goods and emergency personnel from the airports, that serve as emergency hubs, to disaster sites. Numerical examples with different road disruption scenarios are introduced to illustrate the reduction of travel cost by introducing the emergency ports for eVTOL aircrafts.
