VISSIM 5.30-05 User Manual

Building an Abstract Network
► There can be more than one edge between two nodes
► The intra-node edges represent the turning movements but they have a
real length in VISSIM
The edges are the basic building blocks of the routes in route search, i.e. a
route is a sequence of edges. For all the edges travel times and costs are
computed from the simulation providing the information needed for the route
choice model.
The edges automatically constructed by VISSIM can be visualized in the
following way:
1. In the Nodes edit mode you can call the Edge Selection window via
EDIT – EDGE SELECTION... if the network contains at least one node with
active option for Dyn. Assignment.
If a node is currently selected in the network when the Edge selection
window is called, this node will also be selected in the window´s selection
lists.
The lists in the Edge selection window contain only those nodes for which
option for Dyn. Assignment has been checked.
2. In the window, choose a pair of nodes by selecting the numbers from the
From Node and To Node lists.
3. From the top list of all available edges between the selected nodes,
choose an edge to show its graphical representation in the VISSIM
network (as a yellow or red band).
