Feature Description

The Update Edge Weight function is used to temporarily update weight values on network edges in memory.

Note the following when using Update Edge Weight:

• Updates are temporary and will not be saved to fields in the network data. Updated results will be cleared automatically after closing the network layer.
• Setting an edge as a barrier will change its weight value to -1.
• Both forward and reverse weight values of an edge can be updated simultaneously. Select the appropriate edge direction in the "Start Stop ID→End ID" column using the edge ID during updates.

Steps

1. Open the network dataset in the current map.
2. In the Network Analysis Environment Settings window, configure weight fields, node/edge ID fields, etc. For details about this window, see the Network Analysis Environment Settings Window page.
3. On the Environment Settings window toolbar, click the "Weight Settings" drop-down button and select "Update Edge Weight" to open the dialog.
4. Click an edge on the network layer to select it. The selected edge information will be automatically added to the left list. The right list displays forward/reverse weight values. Modify weight values or set edges as barriers. Updated barrier edges are highlighted in red, while non-barrier edges use other colors.
5. Continue updating weights for other edges.
6. Use toolbar buttons in the "Edge Weight Values" dialog to search, hide/show, or remove edges in the list.
7. After configuration, click "Apply" to save changes, or click "Close" to exit without saving.
