Calculates the proportion of intersection types for subgraph around each node if
radius is set, or for whole graph, if radius=None.
Subgraph is generated around each node within set radius. If distance=None,
radius will define topological distance, otherwise it uses values in distance
Graph representing street network.
Ideally generated from GeoDataFrame using momepy.gdf_to_nx()
Include all neighbors of distance <= radius from n
attribute name for 3-way intersections proportion
attribute name for 4-way intersections proportion
attribute name for deadends proportion
name of attribute of node degree (momepy.node_degree())
Use specified edge data key as distance.
For example, setting distance=’weight’ will use the edge weight to
measure the distance from the node n.
if True, shows progress bars in loops and indication of steps

dict with proportions for graph if radius=None
