Method Detail

init

public final void init(StrategicalPlanner strategicalPlanner,
                       nl.tudelft.simulation.language.d3.DirectedPoint initialLocation,
                       org.djunits.value.vdouble.scalar.Speed initialSpeed)
                throws nl.tudelft.simulation.dsol.SimRuntimeException,
                       GTUException

Initialize the GTU at a location and speed, and give it a mission to fulfill through the strategical planner.

Parameters:

strategicalPlanner - StrategicalPlanner; the strategical planner responsible for the overall 'mission' of the GTU, usually indicating where it needs to go. It operates by instantiating tactical planners to do the work.

initialLocation - DirectedPoint; the initial location (and direction) of the GTU

initialSpeed - Speed; the initial speed of the GTU

Throws:

nl.tudelft.simulation.dsol.SimRuntimeException - when scheduling after the first move fails

GTUException - when the preconditions of the parameters are not met or when the construction of the original waiting path fails

destroy

public void destroy()

Destructor. Don't forget to call with super.destroy() from any override to avoid memory leaks in the network.

Specified by:

destroy in interface GTU

move

protected void move(nl.tudelft.simulation.language.d3.DirectedPoint fromLocation)
             throws nl.tudelft.simulation.dsol.SimRuntimeException,
                    OperationalPlanException,
                    GTUException,
                    NetworkException,
                    ParameterException

Move from the current location according to an operational plan to a location that will bring us nearer to reaching the location provided by the strategical planner.
This method can be overridden to carry out specific behavior during the execution of the plan (e.g., scheduling of triggers, entering or leaving lanes, etc.). Please bear in mind that the call to super.move() is essential, and that one has to take care to handle the situation that the plan gets interrupted.

Parameters:

fromLocation - the last known location (initial location, or end location of the previous operational plan)

Throws:

nl.tudelft.simulation.dsol.SimRuntimeException - when scheduling of the next move fails

OperationalPlanException - when there is a problem creating a good path for the GTU

GTUException - when there is a problem with the state of the GTU when planning a path

NetworkException - in case of a problem with the network, e.g., a dead end where it is not expected

ParameterException - in there is a parameter problem

interruptMove

protected void interruptMove()
                      throws nl.tudelft.simulation.dsol.SimRuntimeException,
                             OperationalPlanException,
                             GTUException,
                             NetworkException,
                             ParameterException

Interrupt the move and ask for a new plan. This method can be overridden to carry out the bookkeeping needed when the current plan gets interrupted.

Throws:

OperationalPlanException - when there was a problem retrieving the location from the running plan

nl.tudelft.simulation.dsol.SimRuntimeException - when scheduling of the next move fails

OperationalPlanException - when there is a problem creating a good path for the GTU

GTUException - when there is a problem with the state of the GTU when planning a path

NetworkException - in case of a problem with the network, e.g., unreachability of a certain point

ParameterException - when there is a problem with a parameter
