UNMANNED AERIAL VEHICLES (UAV) PATH PLANNING TECHNIQUES AND CONSTRAINTS IN URBAN AIRSPACE INTEGRATION: LITERATURE REVIEW

Abstract

Unmanned Aerial Vehicles (UAVs), commonly known as drones, have revolutionized numerous industries by offering unprecedented capabilities and possibilities. However, the widespread adoption of UAVs presents significant challenges related to safety, airspace management, and regulatory compliance. In this review paper, we emphasize the importance of UAVs and how the implementation of an efficient path-planning system will ensure safe and effective UAV operations. We provide an overview of the most recent methodologies found in the literature. Firstly, we present the wide range of applications that UAVs have found in various industries. Secondly, we highlight the most critical challenges that we must overcome to enable the seamless integration of UAVs into the airspace. Finally, we provide an overview of the most recent methodologies and approaches to tackle path planning. This analysis highlights the diversity of algorithms used for UAV path planning and provides insights into their strengths and limitations. Our main goal is to become acquainted with the problem variants, applied methodologies, and the state-of-the-art challenges in this field and to identify the possible points of improvements and potential contributions.
