拓扑理论下乡村路网布局算法设计

乡村振兴背景下，乡村居民出行需求和乡村路网布局理论建设极为重要。为了提高乡村路网效率，设计基于拓扑理论的乡村路网布局算法。该方法考虑径向网络的拓扑结构，并计算了城乡交通的特征。根据特征计算结果，采用灰度相关分析方法计算了交通节点重要性指标的目标权值。结合交通节点的动态聚类结果，构建乡村道路布局规划模型，并以出行时间为目标求解该模型，完成布局规划算法的设计。结果表明，该算法在提高效率的基础上，较传统的样条法和GIS-TransCAD法，能够有效地改善城乡道路分布的平衡性和连通性。

Algorithm Design of Rural Road Network Layout based on Topology

In the context of rural revitalization, the needs of rural residents'' travel needs and the theoretical construc-tion of rural road network layout are extremely important. In order to improve the efficiency of rural road network, an algorithm based on topology theory is designed. The method is considereds through the topol-ogy of the radial network and calculates calculated with the characteristics of urban and rural traffic. Ac-cording to the feature results, the target weight of the importance index of the traffic node is calculated by the gray correlation analysis method. Combined with the dynamic clustering results of traffic nodes, a rural road layout planning model is constructed, and this model is solved with the travel time as the goal to com-plete the design of the layout planningthis algorithm. The results show that on the basis of improving the efficiency, the this algorithm can effectively improve the equilibrium and connectivity of urban and rural road distribution, compared with the traditional spline method and GIS-TransCAD method.
