Research on air route network nodes optimization with avoiding the three areas

The previous ARN planning methods pay more attention to the flight paths after planning, and their purposes are to get more convenient, efficient, or safer flight paths. China has a giant airspace with many three areas, and the three areas must be avoided in the process of ARN planning inevitably, which is not implemented in the previous work. CA model proposed in this paper improved the safety of the ARN. It also completed the ARN node optimization and avoided the three areas. It provided not only an effective solution method for the ongoing ARN planning and adjustment under China airspace management system, but also a new train of thought about ARN node optimization for other countries with similar airspace characteristics.
