<｜begin▁of▁sentence｜>### Instruction:
As a policy analyst working on urban planning simulations, imagine we are conceptualizing a new intersection design that must incorporate four distinct roadways, where each roadway is represented as a node in a transportation model. This model is analogous to a planar maximal graph due to the necessity for an efficient layout without overlapping routes. Could you determine an optimal configuration for the intersection where the representation of each roadway (node) is positioned to ensure clear, non-overlapping pathways (edges)? This configuration should reflect the underlying planar nature of our model, ensuring a realistic and practical representation in the simulation. To achieve this objective and envision the proposed design, what would be the calculated coordinates for each roadway within the network model, obtaining a layout where traffic flow is smoothly directed along each path without intersectional conflicts?
### Response:
import networkx as nx

# Create a planar graph
G = nx.planar_maximal_graph(4)

# Compute the planar layout
pos = nx.planar_layout(G)

print(pos)
