Unmanned Aerial Vehicle Route Intersection Control Method Based on the"Signal Lamp"Strategy:Taking the Airspace of Hangzhou Huazheng Take-off and Landing Field as an Example
In recent years,the rapid development of unmanned aerial vehicle short distance logistics transportation in urban scenari-os has led to widespread attention to urban airspace planning issues.Route intersections where unmanned aerial vehicle routes converge was selected as the research object.Firstly,the design influencing factors and current research status of route intersections were ana-lyzed.Then,controlled level crossings were selected for research,and the ground"signal lamp"strategy was introduced for optimiza-tion.Based on the operational characteristics of level crossings and unmanned aerial vehicles,a universal intersection model was pro-posed for unmanned aerial vehicle routes and an optimized control strategy for signal lamp.In the real environment of Hangzhou Hua-zheng UAV takeoff and landing site,simulation has verified that the control strategy proposed can reduce average delay while ensuring traffic capacity.Results have important guiding significance for the design and control of future unmanned aerial vehicle route intersec-tions.
