Class SL3TLC

java.lang.Object
  org.jscience.architecture.traffic.algorithms.tlc.TLController
      org.jscience.architecture.traffic.algorithms.tlc.SL3TLC

All Implemented Interfaces:

InstantiationAssistant, TwoStageLoader, XMLSerializable

public class SL3TLC
extends TLController
implements InstantiationAssistant

This controller will decide it's Q values for the traffic lights according to the traffic situation on the lane connected to the TrafficLight. It will learn how to alter it's outcome by reinforcement learning.
