8.2.3.3 Time-Time Diagram (*.AZZ)
The time-time diagram shows green time against the time of preemption call
for up to 4 signal groups (phases). VISSIM creates a separate diagram for
each nested loop in relationship to the call time point of the first loop.
To get a time-time diagram follow the steps outlined below:
1. Use an external text editor to create a demand configuration file *.ZZD
that contains up to 4 signal groups (phases) using the following syntax:
-- Configuration File for Time-Time Diagram for VISSIM/Test/Loop
-- 185p98s4.ZZD
LSA 1 -- controller #
-- analyzed signal groups (phases):
SGP 2 5 204
2. Generate the time-time diagram file with the extension *.AZZ via LOOP –
ANALYZE – TIME-TIME-DIAGRAM.... Use the previously generated loop
output file *.SLO. It will have the following content:
A = 2
B = 5
C = 2 + 5
D = 204
E = 2 + 204
F = 5 + 204
G = 2 + 5 + 204
10 20 30 40 50 60

The first column shows the time of preemption call of the test phase, the
heading line depicts the cycle time of the resulting timing plan as
illustrated to the right of each time of preemption using a letter coding
scheme. Each letter represents a combination of one or more signal
groups (phases) that show green. The legend at the top of the file shows
the relation of letters and signal groups (phases).
