OSMNX是否可以通过长度和旅行时间来优化路线？

Question

我想计算路线优化距离和旅行时间。我可以仅优化一个属性。

这是我的代码：

origin = (-33.4667,-70.7208)
destiny = (-33.367204, -70.506080) 



orig_node = ox.distance.nearest_nodes(graph, origin[1],origin[0])
target_node = ox.distance.nearest_nodes(graph, destiny[1],destiny[0])

route = ox.distance.shortest_path(graph, orig_node, target_node, weight='travel-time')

length = int(sum(ox.utils_graph.get_route_edge_attributes(graph, route, "length")))
time = int(sum(ox.utils_graph.get_route_edge_attributes(graph, route, "time")))

print('Distancia: ',length/1000,' km') # prints 9201.784
print('Tiempo: ',time/60,' min')
ox.folium.plot_route_folium(graph, route, route_map=None, popup_attribute=None, tiles='cartodbpositron', zoom=1, fit_bounds=True)

谢谢！
