Class ACGJ2

java.lang.Object
  org.jscience.architecture.traffic.algorithms.tlc.TLController
      org.jscience.architecture.traffic.algorithms.tlc.ACGJ2

All Implemented Interfaces:

InstantiationAssistant, TwoStageLoader, XMLSerializable

public class ACGJ2
extends TLController
implements XMLSerializable, TwoStageLoader, InstantiationAssistant

This algorithm will, when it starts, handle like Longest Queue, but it can do more things: 1. It prevents infinite waiting of Roadusers 2. It tries to create green waves between busy nodes. The green_wave-factor is editable as a parameter. 3. The algorithm can be stimulated to develop patterns in TL-configuration-settings, therefore it remembers the last 100 configurations. This pattern factor is also editable 4. This algorithm has a keep green factor. This editable factor is an extra weight to keep the lights green, that were green in the previous cycle.
