機上周辺監視による一方向航空交通流の制御

抄録

A decentralized control of an air traffic flow on an oceanic route is discussed. This study aims to clarify a fundamental strategy for unidirectional air traffic flow control. It is assumed that the decentralized control is made using airborne surveillance systems. The separation control between aircraft is made by turning, and 3 types of surveillance are compared: foreside surveillance, omnidirectional surveillance, and extended area omnidirectional surveillance. Through the numerical simulation, where an aircraft merges into the traffic flow, it has been clarified that the separation control by turning always stabilizes the traffic flow. The traffic flow formation is also numerically simulated by giving each aircraft random initial position. The numerical results have revealed that the aircraft control by foreside surveillance leads some aircraft into dead lock states. The aircraft control using the omnidirectional surveillance can avoid such unfavorable situations. The aircraft control by the extended area omnidirectional surveillance can achieve the flow formation with considerably improving safety and pilot workload.
