Define Paths for Assigning Development Traffic to your Street Network

Zones and Gates are not physically connected to the network by links.

Paths are drawn to connect Zones and Gates throughout the network, which allows for the assignments of new trips between Zones and Gates and along the network.

Paths from a Zone to a Gate (outbound paths) are drawn by selecting the Path tool and then clicking on a Zone and intermediate intersections and finally clicking the destination Gate.

Similarly, Paths from a Gate to a Zone (inbound trips) are drawn by clicking on the Gate first, then intermediate intersections and finally clicking the destination Zone. Once defined, Paths can be selected in the Trip Assignment workflow table and the selected Path is displayed graphically in the network window.

To add a Path:

1.  Select the Path icon from the Toolbar.

2.  In the network window, click on the Zone or Gate to start the Path.

3.  Click at the end of the link where the Path will enter the street network.

4.  Click on the next intersection in sequence to include in the Path.

5.  Continue clicking on each intersection to include in the Path. These need not be adjacent.

6.  Click at the end of the link where the Path will enter the street network.

7.  Click on the Zone or Gate to end the Path.

Once a Path is created, select the Path in the table and right-click for the following options:

• Delete Path: completely delete the path from the network
• Duplicate Path: create a duplicate of the Path. This can be used in conjunction with moving the pin that belongs to the zone or gate to create Paths for nearby origins or destinations in a more efficient manner than drawing them from scratch.
• Create Reverse Path: create the Path using the same nodes and links but in the opposite travel direction from the selected Path
