Method for constructing city low-altitude airspace hierarchical planning model facing traffic demand

Abstract

This invention relates to the field of urban low-altitude airspace planning technology, and particularly to a method for constructing a hierarchical planning model for urban low-altitude airspace oriented towards traffic demand. The method for constructing this hierarchical planning model plans each low-altitude altitude layer corresponding to a specific heading angle range. Multiple low-altitude altitude layers can exist within the same heading angle range. The model construction method includes the following steps: First, acquiring aircraft operational demand data between low-altitude take-off and landing points within the study area, and standardizing the angles of direct flight routes between take-off and landing points; second, proposing a method to calculate the average probability of conflict between aircraft within the same layer of traffic flow and between adjacent layers of traffic flow based on the heading extension range; finally, providing an overall method for constructing a hierarchical planning model for urban low-altitude airspace oriented towards traffic demand. By using altitude layering to reduce low-altitude traffic flow operational conflicts, the proposed model considers both the total number of available low-altitude altitude layers and the control of airspace structural complexity while reducing traffic conflicts, thereby effectively improving the safety and manageability of urban low-altitude hierarchical airspace operation.
