如何使用OSMnx获取hov与toll标签值的技术咨询

我想咨询如何使用OSMnx获取hov标签和toll标签的数值，以下是我的初始代码：

import osmnx as ox
import networkx as nx

import numpy as np
import pandas as pd

from pandas import Series, DataFrame

cf = '["highway"~"motorway"]'

G = ox.graph_from_place("Los Angeles County, California, USA", network_type="drive", custom_filter=cf)

G = ox.add_edge_bearings(G)

gdf_edges = ox.graph_to_gdfs(G, nodes=False)
df=pd.DataFrame(gdf_edges).reset_index()
df.columns

初始输出的列名如下：

可以看到结果中没有名为hov或toll的列，因此我想了解如何判断某段高速公路（即边）是否为hov车道或收费道路。

感谢@gboeing的回复，我通过以下代码成功添加了这两个标签：

import osmnx as ox
import networkx as nx

import numpy as np
import pandas as pd

from pandas import Series, DataFrame

ox.settings.useful_tags_way += ["hov"]
ox.settings.useful_tags_way += ["toll"]

cf = '["highway"~"motorway"]'

G = ox.graph_from_place("Los Angeles County, California, USA", network_type="drive", custom_filter=cf)

G = ox.add_edge_bearings(G)

gdf_edges = ox.graph_to_gdfs(G, nodes=False)
df=pd.DataFrame(gdf_edges).reset_index()
df.columns

添加标签后的输出列名如下：
