Method & Evidence

AimHow can a guidance algorithm be developed to ensure conflict-free reinsertion of UAVs from a loiter lane into a main lane within a fixed-wing UAV corridor, considering traffic congestion and urgent destination needs?

MethodAlgorithm Development and Simulation

ProcedureA guidance algorithm was developed to calculate the necessary speed for a loiter UAV transitioning back to the main lane. This algorithm accounts for the number of available loiter slots, UAV speed restrictions, and minimum safety distances. The effectiveness of the algorithm and associated automation strategies were then validated using numerical simulations.

ContextUnmanned Aerial Vehicle (UAV) traffic management and airspace design

Variables

IVNumber of loiter slots, UAV speed limits, minimum safety distance, traffic conditions in the main lane.

DVRequired speed of loiter UAV for safe reinsertion, time to reinsert, number of conflicts/near misses.

CVFixed-wing UAV corridor structure (main lane, loiter lane, transit lanes), equidistant virtual slots, destination urgency.

Strengths & Limitations

Strengths
