Defining acceleration and deceleration functions

You can insert, select and edit acceleration and deceleration functions.

1.  On the Base Data menu, click > Functions.

2.  Select the desired entry:

• Maximum Acceleration
• Desired Acceleration
• Maximum Deceleration
• Desired Deceleration
• Boarding delay

The list of defined objects for the base data type opens.

By default, you can edit the list (Using lists).

3.  In the list, on the toolbar, click the Add button .

The window for the chosen function opens.

4.  Make the desired changes:

Element	Description
Horizontal abscissa	Speed
Vertical ordinate	Acceleration or deceleration value
Three curves	describe the stochastic distribution Median (red disks) Two boundary curves define the bandwidth (green disks)

Vissim uses the units which are selected by default (Selecting network settings for units).

5.  Make the desired changes:

Element	Description
Name	Name of function
km/h	Max. speed of desired speed range
m/s2	top box: maximum acceleration bottom box: minimum acceleration
Best fit	Show curve progression for entire value range

6.  You can change the settings if you wish.

Element	Description
Insert intermediate point	Right-click on the desired position
Move intermediate point	Click intermediate point and drag with the mouse. Progression of the three curves changes in the value range between the limiting intermediate points.
Delete intermediate point	Click the intermediate point and move it to the adjacent start or end point.

7.  Confirm with OK.

You can show the attributes of the acceleration and deceleration functions in the respective attributes list (Attributes of acceleration and deceleration functions).
