Class AbstractGTUGenerator

java.lang.Object

org.opentrafficsim.core.gtu.generator.AbstractGTUGenerator

Direct Known Subclasses:

GTUGeneratorIndividual

public abstract class AbstractGTUGenerator
extends Object

Common code for LaneBasedGTU generators that may have to postpone putting a GTU on the road due to congestion growing into the generator.
Generally, these generators will discover that there is not enough room AFTER having decided what kind (particular length) of GTU will be constructed next. When this happens, the generator must remember the properties of the GTU, but postpone actual generation until there is enough room.
