### Model
from pypdevs.DEVS import *

class TrafficLightAutonomous(AtomicDEVS):
	def __init__(self):
		AtomicDEVS.__init__(self, "Light")
		self.state = "green"

	def intTransition(self):
		state = self.state
		return {"red": "green",
			"yellow": "red",
			"green": "yellow"}[state]

	def timeAdvance(self):
		state = self.state
		return {"red": 60,
			"yellow": 3,
			"green": 57}[state]

### Experiment
from pypdevs.simulator import Simulator

model = TrafficLightAutonomous()
sim = Simulator(model)

sim.setVerbose()
sim.setTerminationTime(500)

sim.simulate()
