Abstract

Integration of Unmanned Aerial Vehicles (UAV) to airspace is an ongoing work and has many safety-critical issues associated with it. Mid-air collision avoidance is one among them. Urban environment presents many obstacles and no-fly zones which make the movement of the aerial vehicles constrained. Geo-fencing in such cluttered environment defines the safe boundary within which the UAVs could fly. Avoidance map is a tool for conflict resolution among UAVs. We propose a new version of avoidance map which accounts for inter-UAV collision avoidance and boundary keeping. Considering a structured UAV traffic, a corridor like environment is envisaged which consists of intersections and lanes. Conflict resolution at intersections and during lane changing using avoidance map is also presented. Further, we present time graded version of avoidance map which predicts the time to collision for a pair of control inputs. The time grading provides more feasible solutions for the UAVs to avoid conflict. The proposed solution for conflict resolution in a constrained environment is a reliable method to ensure safety and bounded flight. © 2022, American Institute of Aeronautics and Astronautics Inc.
