+# Import code for model simulation, but using the minimal kernel:
+from pypdevs.minimal import Simulator
+
+# Import the model to be simulated
+from model import TrafficSystem
+
+#    ======================================================================
+
+# 1. Instantiate the (Coupled or Atomic) DEVS at the root of the 
+#  hierarchical model. This effectively instantiates the whole model 
+#  thanks to the recursion in the DEVS model constructors (__init__).
+#
+trafficSystem = TrafficSystem(name="trafficSystem")
+
+#    ======================================================================
+
+# 2. Link the model to a DEVS Simulator: 
+#  i.e., create an instance of the 'Simulator' class,
+#  using the model as a parameter.
+sim = Simulator(trafficSystem)
+
+#    ======================================================================
+
+# 3. Perform all necessary configurations, with the minimal kernel, only setTerminationTime is supported.
+#    e.g. to simulate until simulation time 400.0 is reached
+sim.setTerminationTime(400.0)
+
+#    ======================================================================
+
+# 4. Simulate the model
+sim.simulate()
+
+#    ======================================================================
+
+# 5. (optional) Extract data from the simulated model
