Change road network to bidirectional in osmnx
问题
我想知道是否可以使用osmnx将所有道路网络设置为双向？我希望它是双向的，而不是无向的，因为我仍然希望使用一些函数，比如osmnx.truncate。所以osmnx.get_undirected(G)不能帮助我。
我看到@gboeing提到可以通过更改全局设置来实现这一点。但我不确定如何做到这一点。有两个问题：
-
全局设置存储在
settings.py文件中。我如何创建一个新文件并强制osmnx使用新的settings.py文件？ -
如果我想使所有边都是双向的，我只需简单地设置
bidirectiional_network_types=['all']吗？
英文:
I wonder if I can set all road networks to bidirectional using osmnx? I hope it is bidirectional rather than undirected because I still hope to use some functions like osmnx.truncate. So osmnx.get_undirected(G) cannot help me.
I saw @gboeing mentioned this can be done by changing the global settings. But I am not sure how to do that. Two questions
-
The global settings are stored in
settings.pyfile. How can I create a new file and forceosmnxuses the newsettings.pyfile? -
If I want to make all edges bidirectional, can I just simply set
bidirectiional_network_types=['all']?

您可以通过在 osmnx.settings 内设置变量来更改 osmnx 设置。示例：
import osmnx
osmnx.settings.bidirectional_network_types = ["walk", "drive"]
如果我想使所有边都是双向的，我只需简单地设置 bidirectional_network_types=["all"] 吗？
不，这不会起作用。您要使双向的网络类型必须与您在函数中使用的 network_type 匹配，例如 graph_from_address()。在检查 bidirectional_network_types 列表时，它会按照以下方式检查：
bidirectional = network_type in settings.bidirectional_network_types
换句话说，参数 network_type 必须与 bidirectional_network_types 中的一个条目完全匹配，才能被视为双向网络。

You can alter osmnx settings by setting variables within osmnx.settings. Example:
import osmnx
osmnx.settings.bidirectional_network_types = ["walk", "drive"]
>If I want to make all edges bidirectional, can I just simply set bidirectiional_network_types=['all']?
No, that will not work. The network type you are making bidirectional must match the network_type you're using in functions such as graph_from_address(). When it checks the bidirectional_network_types list, it checks it in the following fashion:
bidirectional = network_type in settings.bidirectional_network_types
In other words, the argument network_type must exactly match one of the entries inside bidirectional_network_types to be treated as a bidirectional network.
