Since you want the traffic system to go from "Start" to "PrepareToStop" state for both the cases of button. I am assuming that you want to immediately transition to "PrepareToStop" in case button value is 1, or after some time if button value is 0.
In Stateflow, you can use logical conditions to specify multiple criteria for transitions.
For delayed transitions when the button value is 0, the "after(time, sec)" function can be employed. This function is a temporal logic operator that triggers transitions based on elapsed time.
To achieve your requirement, you can use the following condition:
[button == 1 || (button == 0 && after(5, sec))].
For more details, you can refer to the MathWorks documentation:
