VISSIM 5.30-05 User Manual

Building an Abstract Network
An edge can be banned completely from being used with Dynamic
Assignment by selecting the option Edge Closed while the respective
edge is selected. The edge is then shown in red.
An edge between nodes is ignored in the Dynamic Assignment if it contains
more than three connections (possibly across several connectors) from a
link back to the same link. Cost and path files from VISSIM 5.20 which
contain such edges cannot be used anymore.
An edge is ignored in the Dynamic Assignment if it contains more than one
parking lot extending over all lanes (i.e. zone connectors and abstract
parking lots on any link and real parking spaces on one-lane links only, cf.
section 12.3.1). Cost and path files from VISSIM 5.20 which contain such
edges cannot be used anymore.
12.3.4 Check Nodes/Edges
The node/edge structure is checked for errors, such as overlapping nodes.
For this step, the Nodes editing mode needs to be active.
Nodes and edges are checked as
follows:
1. Click the Nodes editing mode.
2. Click menu EDIT – CHECK NODES
/ EDGES
The node/edge structure is
checked.
12.3.4.1 Correction of Overlapping Nodes
Nodes may not overlap.
VISSIM will show an error message if a network file *.INP containing
overlapping nodes is opened or if a node is defined that overlaps the polygon
of a neighbouring node.
Solution in VISSIM
The error message and the numbers of the overlapping nodes are listed in
the log window.
