Question 2 Consider the following Traffic Light System specification and transition diagram in figure 2 below. Traffic light system works as follow: Whenever the system start-up, the red light on, and the other lights off. When the red light on, it will on for 10 seconds, then the red light off and the green lights on. When the green light on, it will on for 10 seconds, then the green light off and the orange light on. When the orange light on, it will on for 2 seconds, then the orange light off and the red light on. The input value is the current traffic light colour (either red, green or yellow), and the duration in seconds, whilst the output is the next traffic light colour.
