createEmptyLinkSegmentCostArray

public static double[] createEmptyLinkSegmentCostArray(UntypedPhysicalNetwork network,
                                                       Zoning zoning)

Create an empty cost array for all link segments in both virtual and physical part of the network

Parameters:

network - to use

zoning - to apply to virtual part of network

Returns:

generalised cost array by link segment id

createEmptyLinkSegmentCostArray

public static double[] createEmptyLinkSegmentCostArray(UntypedPhysicalNetwork network)

Create an empty cost array for all physical link segments assuming ONLY physical link segments exist

Parameters:

network - to use

Returns:

generalised cost array by link segment id

populateModalVirtualLinkSegmentCosts

public static void populateModalVirtualLinkSegmentCosts(Mode mode,
                                                        VirtualCost virtualCost,
                                                        VirtualNetwork virtualNetwork,
                                                        double[] costArray)

Populate part of cost array for virtual link segment costs based on the concrete cost class, for a given mode

Parameters:

mode - to use

virtualCost - to apply to virtual part of network

virtualNetwork - virtualNetwork containing virtual part of the network

costArray - to fill

populateModalPhysicalLinkSegmentCosts

public static void populateModalPhysicalLinkSegmentCosts(Mode mode,
                                                         AbstractPhysicalCost physicalCost,
                                                         UntypedPhysicalNetwork network,
                                                         double[] costArray)

Populate part of cost array with physical link segment costs based on the concrete cost class, for a given mode

Parameters:

mode - to use

physicalCost - to apply to physical part of network

network - physical network

costArray - to fill

createAndPopulateModalSegmentCost

public static double[] createAndPopulateModalSegmentCost(Mode mode,
                                                         AbstractPhysicalCost physicalCost,
                                                         UntypedPhysicalNetwork network)

Populate cost array with only physical link segment costs based on the concrete cost classes, for given mode. Note that this requires no edge segments of any other type than physical link segments to be present, otherwise the indexing in the raw cost array may be inconsistent

Parameters:

mode - to use

physicalCost - to apply to physical part of network

network - physical network

Returns:

generalised cost array by link segment id

createAndPopulateModalSegmentCost

public static double[] createAndPopulateModalSegmentCost(Mode mode,
                                                         VirtualCost virtualCost,
                                                         AbstractPhysicalCost physicalCost,
                                                         UntypedPhysicalNetwork network,
                                                         Zoning zoning)

Parameters:

mode - to use

virtualCost - to apply to virtual part of network

physicalCost - to apply to physical part of network

network - physical network

zoning - zoning containing virtual part of the network

Returns:

generalised cost array by link segment id
