Method Detail

setConnectoidSpeed

public void setConnectoidSpeed(double connectoidSpeed)

set the connectoid speed

Parameters:

connectoidSpeed - the speed

initialiseBeforeSimulation

public void initialiseBeforeSimulation(VirtualNetwork virtualNetwork)
                                throws PlanItException

Initialize the virtual cost component

Specified by:

initialiseBeforeSimulation in class AbstractVirtualCost

Parameters:

virtualNetwork - the virtual network

Throws:

PlanItException - thrown if a link/mode combination exists for which no cost parameters have been set

updateTimePeriod

public void updateTimePeriod(TimePeriod timePeriod)

Provide the cost calculation with information regarding the time period for which the cost is to be calculated

Specified by:

updateTimePeriod in class AbstractVirtualCost

Parameters:

timePeriod - to apply

getGeneralisedCost

public double getGeneralisedCost(Mode mode,
                                 ConnectoidSegment connectoidSegment)

Return the connectoid travel time using speed

Parameters:

mode - the mode of travel

connectoidSegment - the connectoid segment

Returns:

the travel time for this connectoid segment

populateWithCost

public void populateWithCost(VirtualNetwork virtualNetwork,
                             Mode mode,
                             double[] costToFill)
                      throws PlanItException

Invoker expects (mode specific ) costs in passed in array to be filled, where each entry signifies a link segment by its id

Parameters:

virtualNetwork - the cost pertains to

mode - the mode these costs pertain to

costToFill - array of link segment costs identified by the link segment's internal id

Throws:

PlanItException - thrown if error

clone

public SpeedConnectoidTravelTimeCost clone()

Create a shallow copy of this entity

Specified by:

clone in interface IdAble

Specified by:

clone in class PlanitComponent<AbstractVirtualCost>

Returns:

shallow copy of entity

reset

public void reset()

Chosen speed is considered configuration not internal state, so upon resetting the chosen speed remains in tact

Specified by:

reset in class PlanitComponent<AbstractVirtualCost>

getTravelTimeCost

public double getTravelTimeCost(Mode mode,
                                ConnectoidSegment connectoidSegment)

Returns the generalised cost of travel along an edge segment for a specified mode

Parameters:

mode - the specified mode of travel

connectoidSegment - the specified edge segment (which can be physical or virtual)

Returns:

the cost of travel along the specified segment

getDTravelTimeDFlow

public double getDTravelTimeDFlow(boolean uncongested,
