Safety landings of Urban Air Mobility (UAM) vehicles in dense urban environments pose risks to third parties, including ground traffic and pedestrians. While additional landing sites may be considered during flight planning, their availability during operations is strongly influenced by dynamic ground traffic conditions. In conventional aviation, Extended Diversion Time Operations define alternate aerodromes for diversion scenarios; however, an equivalent operational concept remains limited for UAM in constrained urban areas.rnrnThis study investigates the use of signalised urban intersections as temporary emergency safety landing sites enabled through advanced ground traffic management. A network-oriented intersection management concept is formulated and initially evaluated using a microscopic simulation framework based on the Simulation of Urban Mobility (SUMO), in which emergency landing scenarios are represented through controlled intersection restrictions. Baseline results reveal significant network-level traffic impacts under uncoordinated emergency handling, highlighting the limitations of localised responses and motivating the need for coordinated, optimisation-based air–ground traffic management strategies.
