在python的OSMnx中绘制有限速条件的边

import osmnx as ox
import networkx as nx
import matplotlib.pyplot as plt

def plot_speed_limit_edges(place, network_type='all'):
    # 根据地点名称获取网络图
    G = ox.graph_from_place(place, network_type=network_type)
    # 获取所有边的速度属性
    speeds = nx.get_edge_attributes(G, 'maxspeed')

    # 绘制网络图
    fig, ax = ox.plot_graph(G, edge_color='gray', node_color='w', node_edgecolor='black',
                            node_size=30, node_zorder=2)

    # 遍历每条边
    for u, v, key, data in G.edges(keys=True, data=True):
        if 'maxspeed' in data:
            # 获取有限速条件
            max_speed = data['maxspeed']
            # 获取边的几何形状
            edge = G[u][v][key]
            # 绘制边的几何形状
            ox.plot.make_folium_polyline(edge, color='red', weight=3, opacity=1, ax=ax)

            # 获取边的中点坐标
            x, y = edge['geometry'].xy
            mid_x = (x[0] + x[-1]) / 2
            mid_y = (y[0] + y[-1]) / 2

            # 在边的中点坐标处添加有限速条件文本
            ax.text(mid_x, mid_y, max_speed, fontsize=8, ha='center', color='red')

    # 显示绘制结果
    plt.show()

place = "Your Place"  # 替换为你感兴趣的地点名称
