摘要:

低空开发与利用正逐渐成为推动低空经济发展的战略支撑,但低空飞行器的大规模涌入使城市上空面临前所未有的安全挑战。如何科学、全面、精准量化复杂城市低空环境的风险分布,生成安全、高效的低空航路已成为关键科学问题。现有研究忽视城市低空与地面空间的多维耦合风险,航路生成算法局限于局部搜索,难以实现风险准确量化与最优航路生成。为此,本文提出以地面风险为核心约束的低空风险量化方法与航路智能生成模型。首先,融合人口密度、建筑密度与用地类型3类数据,提出低空风险因子量化与组合赋权方法,构建了高-中-低多级低空风险分布地图。然后,提出基于自适应粒子群优化算法的航路智能生成模型(APSO-AR),通过自适应航路节点构建、风险感知采样与间隔惩罚机制,实现航路对地面高风险区域的全局感知与规避。最后,以武汉市为研究区域进行航路生成试验,结果表明,相较于蚁群算法、遗传算法、risk A*算法及传统粒子群算法,APSO-AR生成的航路长度平均降低了12.0%,风险度平均降低了30.7%,代码运行时长平均降低了77.4%,在航程效率,风险规避与空间合理性之间取得较好平衡。本文提供了“风险量化—航路生成”的技术路径,为城市低空风险地图构建与航路规划提供方法支撑。

Abstract:

The development and utilization of low-altitude airspace are gradually becoming a strategic pillar for advancing the low-altitude economy. However, the massive influx of low-altitude aircraft poses unprecedented safety challenges over urban areas. How to scientifically, comprehensively, and accurately quantify the risk distribution in complex urban low-altitude environments, and subsequently generate safe and efficient air routes, has become a critical scientific problem. Existing research often overlooks the multi-dimensional coupled risks between urban low-altitude and ground space, and air route generation algorithms are typically confined to local search, making it difficult to achieve accurate risk quantification and globally optimal route generation. To this end, this paper proposes a low-altitude risk quantification method and an intelligent route generation model constrained primarily by ground risk. Firstly, by fusing three types of data—population density, building density, and land use type—we propose a low-altitude risk factor quantification and combined weighting method to construct a high-medium-low multi-level low-altitude risk distribution map. Secondly, an intelligent air route generation model based on adaptive particle swarm optimization (APSO-AR) is proposed. By incorporating an adaptive air route node construction, a risk perception sampling mechanism, and an interval penalty mechanism, the model achieves global risk perception and optimal route generation for low-altitude aircraft within complex urban scenes. Finally, air route generation experiments were conducted using Wuhan city as the research area. The results demonstrate that, compared to ant colony optimization (ACO), genetic algorithm (GA), risk A* algorithm, and the traditional particle swarm optimization (PSO), the air routes generated by APSO-AR show an average reduction of 12.0% in route length and an average reduction of 30.7% in risk level, while the average code runtime is reduced by 77.4%. The model simultaneously ensures route optimality, risk minimization, and global rationality. This paper provides a new technical path for “risk quantification—route generation”, providing methodological support for urban low-altitude risk map construction and route planning.
