Class AbstractLaneBasedStrategicalPlannerFactory<T extends LaneBasedStrategicalPlanner>

java.lang.Object

org.opentrafficsim.road.gtu.strategical.AbstractLaneBasedStrategicalPlannerFactory<T>

Type Parameters:

T - class of the strategical planner generated

All Implemented Interfaces:

LaneBasedStrategicalPlannerFactory<T>

Direct Known Subclasses:

LaneBasedStrategicalRoutePlannerFactory

public abstract class AbstractLaneBasedStrategicalPlannerFactory<T extends LaneBasedStrategicalPlanner>
extends Object
implements LaneBasedStrategicalPlannerFactory<T>

Factory for creating LaneBasedStrategicalRoutePlanner using any LaneBasedTacticalPlannerFactory. This abstract class deals with forwarding peeking from the GTU generator to the tactical planner factory. Parameters are set using a ParameterFactory, after the method setParameters() has been called, which subclasses need to implement.

Constructor Detail

AbstractLaneBasedStrategicalPlannerFactory

public AbstractLaneBasedStrategicalPlannerFactory(LaneBasedTacticalPlannerFactory<? extends LaneBasedTacticalPlanner> tacticalPlannerFactory)

Constructor with factory for tactical planners.

Parameters:

tacticalPlannerFactory - LaneBasedTacticalPlannerFactory<? extends LaneBasedTacticalPlanner>; factory for tactical planners

AbstractLaneBasedStrategicalPlannerFactory

public AbstractLaneBasedStrategicalPlannerFactory(LaneBasedTacticalPlannerFactory<? extends LaneBasedTacticalPlanner> tacticalPlannerFactory,
                                                  ParameterFactory parametersFactory)

Constructor with factory for tactical planners.

Parameters:

tacticalPlannerFactory - LaneBasedTacticalPlannerFactory<? extends LaneBasedTacticalPlanner>; factory for tactical planners

parametersFactory - ParameterFactory; factory for parameters

Method Detail

peekDesiredSpeed

public final Speed peekDesiredSpeed(GTUType gtuType,
                                    Speed speedLimit,
                                    Speed maxGtuSpeed)
                             throws GTUException

Peek to see the desired speed of the next GTU to be generated at the given location. The default implementation returns null, at which point the GTU generator will use some other speed.

Specified by:

peekDesiredSpeed in interface LaneBasedStrategicalPlannerFactory<T extends LaneBasedStrategicalPlanner>

Parameters:

gtuType - GTUType; GTU type

speedLimit - Speed; speed limit

maxGtuSpeed - Speed; maximum GTU speed

Returns:

desired speed of the next GTU to be generated at the given location, may be null at which point the GTU generator will use some other speed

Throws:

GTUException - on parameter exception or network exception

peekDesiredHeadway

public final Length peekDesiredHeadway(GTUType gtuType,
                                       Speed speed)
                                throws GTUException

Peek to see the desired headway of the next GTU to be generated at the given speed. The default implementation returns null, at which point the GTU generator will only generate GTU's at fixed locations.

Specified by:

peekDesiredHeadway in interface LaneBasedStrategicalPlannerFactory<T extends LaneBasedStrategicalPlanner>

Parameters:

gtuType - GTUType; GTU type

speed - Speed; speed the GTU might be generated at

Returns:

Length; desired headway of the next GTU to be generated at the given speed, may be null at which point the GTU generator only generate GTU's at fixed locations

Throws:

GTUException - on parameter exception or network exception

getParameters

protected abstract org.opentrafficsim.base.parameters.Parameters getParameters()

Returns parameters specific to the strategical planner. The input already contains parameters from the tactical planner. After this method, the ParameterFactory sets or overwrites additional parameters. Hence, this method may set default (distributed) values for parameters specific to the strategical planner.

Returns:

parameters Parameters; parameters for the strategical planner, may be null

nextParameters

protected final org.opentrafficsim.base.parameters.Parameters nextParameters(GTUType gtuType)
                                                                      throws GTUException

Returns the parameters for the next GTU.

Parameters:

gtuType - GTUType; GTU type of GTU to be generated

Returns:

Parameters; parameters for the next GTU

Throws:

GTUException - on parameter exception

nextTacticalPlanner

protected final LaneBasedTacticalPlanner nextTacticalPlanner(LaneBasedGTU gtu)
                                                      throws GTUException

Returns the next tactical planner.

Parameters:

gtu - LaneBasedGTU; GTU to be generated

Returns:

T; next tactical planner

Throws:

GTUException - on exception during tactical planner creation

getTacticalPlannerFactory

protected final LaneBasedTacticalPlannerFactory<? extends LaneBasedTacticalPlanner> getTacticalPlannerFactory()

Returns the tactical planner factory.

Returns:

LaneBasedTacticalPlannerFactory; tactical planner factory
