Traffic management of airspace with manned and unmanned vehicles is a complex task that requires a clear definition of rules that vehicles should adhere to for smooth and conflict-free movements. Structured traffic acts as an ideal candidate to improve the airspace capacity and reduce the complexity involved. Aerial intersections are novel in this context and require precise management in terms of different parameters like the time involved and vehicle separation. In this work, an intersection planning strategy is proposed in the context of a previously proposed CORRIDRONE architecture. Paths are categorized as a function of the lanes involved in the transition. Intersections are planned as a part of these paths occupying the volume in the airspace. Conflict resolution at intersections is achieved using lane changing. Lane changing method ensures vehicle transit within a prescribed time. The transit path is modeled using polynomial curves with transit geo-fencing that guarantees safety.
