Evaluating signal changes

You can record all changes of the individual signal groups from all signal controllers. Signal controllers must be defined in the network (Modeling signal controllers).

Output data and formats

You can save the following data and data formats:

Showing evaluation of signal changes in a window

1.  On the Evaluation menu, click > Windows > Signal Changes.

The Signal changes window opens in a tab.

2.  Start the simulation (Running a simulation).

In the Signal changes window, the current values of the following data is displayed:

Element Description
SimSec Simulation second [s]
CycSec Cycle time [s]
SC Signal controller number
SG Signal group number
State New signal state
old Time since the last signal state change (= duration of the previous signal state)
Crit Signal controller type
bcSG Signal group which has caused the current signal change. This is supported only by certain controllers for vehicle actuated signals.

A *.lsa file is saved.

Result of evaluation of signal changes

The record file of signal changes *.lsa contains the following information:

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

Signal controller block

All signal groups

Data block

A row is output for each change process of each signal group.

The columns contain the following data (from left to right):

  • Simulation second [s]
  • Cycle time [s]
  • Signal controller number
  • Signal group number
  • New signal state
  • Time since the last signal state change (= duration of the previous signal state)
  • Signal controller type
  • Signal group which has caused the current signal change. This is supported only by certain controllers for vehicle actuated signals.
