- a period of combined intervals (Continued Input: light-grey). In that
case, only the master cell (black) can be edited and affects
automatically all subsequent continued cells.
The background color indicates whether the vehicle volume is
- stochastic (white) or
- exact (yellow).
When EXACT VOLUME is enabled VISSIM generates exactly the edited
number of vehicles to enter the network as opposed to a distribution.
The configuration of the data section can be changed via the context menu.
Select one or multiple cells and call:
● EXACT VOLUME: Volume values are regarded as exact volumes, if this
option is checked. The cells are highlighted in yellow.
● STOCHASTIC VOLUME: Volume values are regarded as stochastic volumes,
if this option is checked. The cells are not highlighted.
● CONTINUED INPUT: Select all cells to be combined (except the master cell)
and check this option to define a combined flow: The master cell is the
one previous to the selected cells; the master cell entry spans over the
selected sequence of time intervals.
- The master cell remains editable, indicated by black text entries.
Changes to the master cell entry are copied to all subsequent cells.
- Grey text entries indicate combined cells (Read-only).
Uncheck this option to separate selected combined cells.

(lower line per time interval) on and off.
● ZOOM: The input´s position in the network is placed in the middle of the
VISSIM window on screen.
6.4.4 Routing Decisions and Routes
A route is a fixed sequence of links and connectors:
► from the routing decision point (red cross-section)
► to at least one destination point (green cross-section).
Each routing decision point can have multiple destinations resembling a
tree with multiple branches.
A route can have any length - from a turning movement at a single junction to
a route that stretches throughout the entire VISSIM network.
A routing decision affects only vehicles of a class that is contained in the
routing decision and not having any routing information. If a vehicle already
has a route assigned to it then it first has to pass its destination point (green
