Class TC3Opt

java.lang.Object
  org.jscience.architecture.traffic.algorithms.tlc.TLController
      org.jscience.architecture.traffic.algorithms.tlc.TC3Opt

All Implemented Interfaces:

Colearning, InstantiationAssistant, TwoStageLoader, XMLSerializable

public class TC3Opt
extends TLController
implements Colearning, InstantiationAssistant

This algorithm works like TC1 with extra functionality. It outcome is adjusted by reinforcement learning. The Q values are created overseeing the whole environment of each traffic light.
