VISSIM 5.30-05 User Manual

Building an Abstract Network
If you do not want to resign those edges, you can do the following:
1. Click the Node mode.
2. On the longer edge, right-click to define
a new node.
This way you have created two new
links and their nodes are not identical.
3. Start the export to VISUM again.
Call the list of all edges of a Dynamic Assignment via menu EDIT – EDGE
SELECTION, it is displayed in the Edge selection window, cf. section 12.3.3.
12.3.4.3 Correction of Unexpected Start/End of Nodes
Nodes can be created from link segments, cf. section 12.3.2. When building
a node/edge structure via CHECK NODES/EDGES, an error message is
displayed if the end or the start of a node cannot be used for the building
process. VISSIM offers to fix damaged link segments.
Solution in VISSIM
Click OK to confim the error messages. The VISSIM window suggests how
to rebuild the nodes.
There are two options provided:
1. Form a node polygon from link segments.
2. Edit link segments.
