1.Start
2.Declare time, prevState, Green=40 sec, Amber=15 sec, Red=40 sec
3.Time start from 0
4.Green 0 < time <= 40?
a) Yes: stay in Green, prevState == go
No: go to #5

5.Amber 40 < time <= 55?
a) Yes: stay in Amber, prevState == go
No: go to #6
b) If interrupt: go to #8
6.Red 55 < time <= 95?
a) Yes: stay in Red, prevState == stop
No: go to #7
b) If interrupt: go to #8
7.Over 95 < time?
a)Yes: go back #3
No: go to #4
b) If Interrupt: go to #8
8. Perfom Interrupt Protocol, go to #3

logic2

1. Start
2. Declare variables:
2.1 Green = 45 sec.
2.2 Amber = 10 sec.
2.3 Total duration = 90 sec.
2.4 Red = Total duration - Green - Amber = 35 sec.
2.5 Red Countdown = Red - 25 sec. = 10 sec.
3. Define initial state: All single lights [off]
4. Startup: The system sends an order [on]
5. If Green Startup first: Get an order
5.1 Duration of the green light [45 sec.]
5.2 Time is over: Go to #6
6. Amber Startup: Get an order
6.1 Duration of the amber light [10 sec.]
6.2 Time is over: Go to #6
7. Red Startup: Get an order
7.1 Duration of the red light [35 sec.]
7.11 Show Red Countdown [10 sec.]
7.2 Time is over: Repeat #5

logic 3
1. Start
2. declaired variable
red light = green + amber = 70 sec
3. red light > 10 ?
3.1 Yes : go to #4
3.2 No : go to #6
4. Is there any situation ?
4.1 Yes : go to #5
4.2 No : go to #6
5. walk button? car sensor?
5.1 walk button : red light turn to 10 sec, go to #6
5.2 car sensor? : red light turn to 10 sec, go to #6
6. the red light keep reducing one sec
7. the red light = 0
8. start the green light
9. End

[Group] Define the 4-light 5-state system that supports the advanced left turn light, request to walk, car sensor, and interrupt features.
1. Start
2. Declared variables
Solid Green + Advanced Left Green Arrow = 15 sec,
Solid Green + Advanced Left Amber Arrow = 5 sec,
Solid Green + Advanced Left Arrow (off) = 45 sec,
