cds_length
Calculates length of cul-de-sacs for subgraph around each node if radius is set, or for whole graph, if radius=None.
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 attribute.
distance=None
Graph representing street network. Ideally generated from GeoDataFrame using momepy.gdf_to_nx()
momepy.gdf_to_nx()
Include all neighbors of distance <= radius from n
if 'sum', calculate total length, if 'mean' calculate mean length
'sum'
'mean'
calculated attribute name
name of attribute of node degree (momepy.node_degree())
momepy.node_degree()
name of attribute of segment length (geographical)
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.
distance=’weight’
weight
if True, shows progress bars in loops and indication of steps
networkx.Graph if radius is set
length of cul-de-sacs for graph if radius=None
Examples
>>> network_graph = mm.cds_length(network_graph, radius=9, mode='mean')
