Arrangement Hierarchy

Once the units have been identified, hierarchal relationships are used to determine the position of the units within the assembly. The following steps are used to determine placement:
  • Select arrangement pattern: horizontal, vertical, or combination of both.
  • Identify units by direction.
  • Identify highway class within a given direction.
  • Identify highway number within a given class.
