Applying weightings to nodes/intersections in OSMNX

I've been searching for a way to apply weightings to the nodes/intersections themselves on OSMNX as opposed to the edges. Anyone know or figured out if the package allows for nodes to be given weightings?

Solution

  • Similar to the answer by Debjit Bhowmick, you could do this more efficiently directly with Networkx:

    import networkx as nx
import osmnx as ox
G = ox.graph_from_place('Piedmont, CA, USA', network_type='drive')

# create node weights
w = {k: 3 if v == 'turning_circle' else 1 for k, v in G.nodes(data='highway')}
nx.set_node_attributes(G, w, 'weight')
