Class SignController

java.lang.Object
  org.jscience.architecture.traffic.algorithms.tlc.SignController

All Implemented Interfaces:

XMLSerializable

public class SignController
extends java.lang.Object
implements XMLSerializable

This is the class for the sign controller. Here is decided how each sign should work. Reward values are gathered for each sign, when set on 'Green' asking the applied TLController. Non-TrafficLight signs can also be implemented when a Q-value algorithm is implemented for the appropiate type of sign. After those values are gathered, this class will select the most rewarding trafficlightconfiguration for each Node and will set the Signs accordingly.

Field Detail

CrossNodesSafely

public static boolean CrossNodesSafely

Indicates if trafficlights must be switched safely or not. Safely means no 2 trafficlights may be turned to green at the same time, if roadusers moving from the drivelanes behind those signs would collide on the node.
