6 The Traffic Network
6.1 Overview
Example
The basic element of a VISSIM traffic network is a link representing a single
(or multiple) lane roadway segment with a specific direction of flow. A
network can be built by connecting links via connectors. Only connected links
allow for continuing traffic. Links that simply overlap (without a connector)
have no interaction with each other.
Network elements can be defined at any location within the traffic network.
They can be edited or deleted.
In the simple network example below, the junction is a signal-controlled
intersection with signal heads and detectors . Additionally some
movements are secured by priority rules (the colors of the network
elements depend on user-defined settings).
Normal display:
The roadwork is displayed in dark
gray showing an intersection with
3 legs and 2 pedestrian crossings.
Center line display:
The same roadwork is displayed
as the center lines of the links
(blue) and connectors (purple).
Selection of network elements
For creating, editing or deleting a network object, the button of the respective
network object type has to be active in the symbol bar.
By default, network objects are selected as follows:
Single-select mode
► By default, a network object is selected by left-clicking directly on the
network object in the VISSIM network display on screen. Double-click
calls the respective Edit attributes window.
► Alternatively, a selection list showing all network objects currently defined
in the VISSIM network for the respective netwok object type can be
called via
- EDIT - SELECTION LIST or
- right-click outside of the network.
Further steps:
- Select network object in the list and click DATA or DELETE.
