public class StationHaltingTrafficLight

extends AbstractVisibleControlPoint

implements nl.tudelft.simulation.dsol.animation.LocatableInterface, StopSignInterface

This class implements the traffic light for the stations. The traffic light has the objective of controlling the behavior of the vehicles at the stations. They have only two states: - red -> to make the vehicles stop at the station - green -> to allow them to depart (after the halting time has passed
