| 摘要: |
| 针对现有低空航路规划方法因随机交叉点过多而难以适用于高密度城市低空运行场景的问题，提出一种面向无人机（Unmanned Aerial Vehicle，UAV）及电推进垂直起降（electric Vertical Take-off and Landing，eVTOL）航空器的城市低空公共航路规划方法。首先，通过构建在垂直分层、由多个圆环层与径向层组成的立体化径向-环状融合航路结构，将随机分布的交会冲突点转化为数量显著减少且位置固定的交会点；再结合圆径飞行规则，实现不同航向飞行器的垂直分离，有效降低冲突风险并显著提升空域容量。仿真结果表明，所提方法的冲突对数量仅为直飞方案的23.37%，充分验证了其在高密度城市低空运行场景中的适用性。 |

| Abstract: |
| For the problem that the existing low altitude route planning methods are difficult to be applied to high-density urban low-altitude operation scenarios due to the excessive number of random intersection points，an urban low-altitude public route planning method for unmanned aerial vehicle(UAV) and electric vertical take-off and landing(eVTOL) aircrafts is proposed.Firstly，by constructing a three-dimensional radial-ring fusion route structure consisting of multiple circular layers and radial layers in the vertical hierarchy，the randomly distributed intersection conflict points are transformed into a significantly reduced number of intersections with fixed locations.Subsequently，by combining with the radial-circular flight rules，the vertical separation of aircrafts with different flight directions is realized，which effectively reduces the risk of conflicts and significantly improves the capacity of the airspace.Simulation results demonstrate that the number of conflict pairs of the proposed method is only 23.37% of that under the direct-flight scheme，which fully verifies its applicability in high-density urban low-altitude operation scenarios. |
