8.2.3.1 Red Time Distribution (*.AWZ)
The red time distribution is a graphical representation of the waiting time for
each signal group (phase).
To get a red time distribution follow the steps outlined below:
1. Via TEST - LOOP – RUN, load an *.SLF file and create a loop output file
*.SLO.
2. Create the red time distribution file via TEST - LOOP – ANALYZE – WAITING
TIMES DISTRIBUTION.... from the *.SLO file.
VISSIM creates a file with the extension *.AWZ and the following content:
1 1 *
2 1 *
3 1 *
4 1 *
5 1 *
6 1 *
7 1 *

9 1 *

1.0
The first column contains the time of preemption call and the second column
shows the resulting waiting time for test phase vehicles. The number of stars
to the right represents the waiting time graphically. The average waiting time
is shown at the bottom. This example shows that preempting light rail
vehicles experience one second of delay for every analyzed preemption
time.
