Saving signal controller green time distribution to a file

You can evaluate the absolute frequencies of the occurrence of green durations and red durations for each signal group. The evaluation also includes the calculated averages of both. Signal controllers must be defined in the network (Modeling signal controllers).

You can save the following data and data formats:

Output	ASCII file	MDB table
Aggregated data	*.lzv	-
Raw data

• Save data to file (Configuring evaluations for direct output)

1.  From the Evaluation menu, choose > Configuration > Direct Output tab.

2.  In the Green time distribution row, select the option Write to file.

3.  Confirm with OK.

4.  Start the simulation (Running a simulation).

After the simulation run, an *.lzv file is saved.

Result of evaluation of signal controller green time distribution

The file of the signal controller green time distribution *.lzv contains the following data:

Element	Description
File title	Name of evaluation
File	Path and name of network file
Comment	Optional comment from the simulation parameters
Date	Time of evaluation
Vissim	Version number, service pack number, build number
Data	The evaluation contains the following data blocks: Data block with average green times for each signal controller Separate data blocks with green times and red times for each signal controller: The columns contain the individual signal groups j The rows contain the green times up to 179 s an red times up to 300 s. All green times from 180 s are combined into one class. Each table entry ij indicates how often the signal group j received a release duration of i seconds. Separate data blocks of all green times and red times with information about their frequency and average for each signal controller and each signal group. In addition, the frequencies are represented graphically in a simple form.

Note: For the graphic representation of green time distribution, you can import the file *.lzv into a spreadsheet program, e.g. Microsoft™ Excel. The block with the tabular green times is particularly suitable in this case.
