Conflict-free trajectory planning for urban air mobility based on an airspace-resource-centric approach

Urban air mobility (UAM) has been attracting stakeholders' attention for its great potential in playing an important role in future urban traffic systems. Expected high density of UAM operation requires advanced management strategy of airspace resources. In this paper, we present an Airspace-Re...
