Specifying the Direction for a Link
Concept Procedure Quick Reference

To specify the direction for a link

  1. Verify that the network topology containing the link is loaded. You can specify link direction for network topologies only.
  2. In the map, double-click the link for which you want to specify direction.

    If more than one topology contains the same link, select one of the topologies. Update the other topologies later.

  3. In the Properties palette, under the Topo properties, choose a setting for the Flow Direction property:
    • Bi-Directional — Movement is allowed in both directions.
    • Forward — Movement is allowed only in the direction that the link was created.
    • Reverse — Movement is allowed only in the opposite direction of the direction that the link was created.

    The new direction setting is assigned to the link.

Note You can also store a direction value in an object data table or an external database table. When you run a shortest path trace, best route analysis, or flood trace, you can specify the location of this data. When storing this data, use 0 for Bi-Directional, 1 for Forward, and -1 for Reverse.
