使用networkx和osmnx将最短路径保存在“结构化文件”中

import networkx as nx
import osmnx as ox

G = nx.DiGraph()

G.add_node(1, pos=(0, 0))  # 添加节点1，设置位置为(0, 0)
G.add_node(2, pos=(1, 1))  # 添加节点2，设置位置为(1, 1)
G.add_edge(1, 2, weight=10)  # 添加从节点1到节点2的有向边，设置权重为10

place_name = "City, Country"  # 设置地点名称，例如"New York, USA"
graph = ox.graph_from_place(place_name, network_type="all")  # 下载地图数据并构建网络图

start_node = 123  # 设置起始节点
end_node = 456  # 设置目标节点
shortest_path = nx.shortest_path(graph, start_node, end_node, weight="length")  # 计算最短路径

import csv

filename = "shortest_path.csv"  # 设置保存路径
with open(filename, "w", newline="") as file:
    writer = csv.writer(file)
    writer.writerow(["Node", "Latitude", "Longitude"])  # 写入表头
    for node in shortest_path:
        latitude, longitude = graph.nodes[node]["y"], graph.nodes[node]["x"]
        writer.writerow([node, latitude, longitude])  # 写入节点信息
