CHAPTER 4. CODING PROCESS

TLDecision holds a tuple of a TrafficLight and a float value to represent the
reward for the TrafficLight to be kept.³

TLCFactory is used to get instances of traffic light controllers. An instance is
created in the method setTLC of SimController.

SignController decides how each sign should work. Only one instance is cre-
ated in the SimModel.

The method switchSigns is called by doStep of SimModel.
