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).

Output data and formats

You can save the following data and data formats:

Output ASCII file MDB table

Aggregated data

*.lzv

-

Raw data

 

 

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.
