The Links layer displays the links network, where each link is defined as an aggregation of streets.
A link is delimited by link nodes.
A link node is a specific point of the link, used for modeling different traffic parameters.
This layer can also display connectors.
A connector is only a virtual/logical link used for connecting a centroid with a link node.
The forecast engine TRE can inject the transport network demand flows into the connector, allowing for their propagation.
The injection can proceed in both directions:
- From the centroid toward the link
- From the link toward the centroid.
Select a link to obtain detailed information and charts about traffic conditions.
Tip: You can get the same result through the operation (→ Showing a selected item).
