The following examples show two networks constructed from roads. In the first example, the points of contact become nodes in the network, with road sections as the connections:
In the second example, a one way road system is extracted. In this example, the direction is important when defining the network.
The end of a one way street can touch either:
· The start of another one way street, or
· Anywhere on a two way street
A two way street can touch either:
· The start of a one way street, or
· Anywhere on a two way street
For a simpler way of defining a one-way system, see Construct a network using disconnect_positions.
