Defining networks from lines

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.
