Attributes of edges

Edges and their attributes are generated with node-edge graphs (Generating a node-edge graph).

1.  Select Network > Edges in the Lists menu.

The list Edges opens. If no node-edge graphs were generated, only the column titles are shown and you must generate node-edge graphs (Generating a node-edge graph).

Note: In lists, you can use the  Attribute selection icon to show and hide attribute values (Selecting attributes and subattributes for columns of a list).

The list on the left may include the following attributes:

Element	Description
No	Unique edge number
FromNode	From-node: Name of the node, on which the edge begins
ToNode	To-node: Name of the node, on which the edge ends
Type	Type of edge is either Dynamic assignment or Evaluation
IsTurn	Is turn:  If this option is selected, the edge is a turn relation.
Closed	Closed:  If this option is selected, the edge is closed. The edge is not taken into consideration in the dynamic assignment. The edge is highlighted in red in network editors if the Synchronization icon has been selected in the Edges list:
Length	Length of the edge in the network in meters
ConvTravTm	Converged (travel time):  If this option is selected, the travel time is converged. The edge fulfills the convergence criterion Travel time on edges for all completed time intervals (Attributes for achieving convergence). The attribute is flagged as irrelevant and is not evaluated as long as there is no new travel time in any time interval, for example, after loading the path file before a simulation run.
ConvVol	Converged (volume):  If this option is selected, the volume is converged. The edge fulfills the convergence criterion Volume on edges for all completed time intervals (Attributes for achieving convergence). The attribute is flagged as irrelevant and is not evaluated as long as there is no new travel time in any time interval, for example, after loading the path file before a simulation run.

Notes: The results of the last iteration are only shown in the list Edges when the cost file and the path file were saved in this iteration. An edge between nodes is ignored in dynamic assignment if it returns to a previously visited link more than three times (for example, if the edge contains more than three parking bays or stop bays). Path files and cost files from older Vissim versions, which contain such edges, can no longer be used. An edge in the dynamic assignment is ignored when it does not contain a parking lot which spans over all of the lanes, i.e. zone connectors and abstract parking lots on all links and real parking spaces only on links with one lane (Modeling parking lots and zones). Path files and cost files from older Vissim versions, which contain such edges, can no longer be used.

Showing and editing dependent objects as relation

The attribute and attribute values of this network object type are shown in the list on the left, which consists of two coupled lists.

1.  In the list on the left, click the desired entry.

The list on the right contains attributes and attribute values of network objects, and/or base data allocated to the network object selected in the list on the left (Using coupled lists):

• To edges
• Link sequence: Numbers of links and connectors via which the edge leads.
• From edges

2.  On the list toolbar, in the Relations list, click the desired entry.

3.  Enter the desired data.

The data is allocated.
