Method Detail

createPath

public static GraphPath<org.opentrafficsim.kpi.sampling.KpiLaneDirection> createPath(String name,
                                                                                     LaneDirection first)
                                                                              throws org.opentrafficsim.core.network.NetworkException

Creates a path starting at the provided lane and moving downstream until a dead-end, split, or loop.

Parameters:

name - String; path name

first - LaneDirection; first lane

Returns:

GraphPath<KpiLaneDirection> path

Throws:

org.opentrafficsim.core.network.NetworkException - when the lane does not have any set speed limit

createPath

public static GraphPath<org.opentrafficsim.kpi.sampling.KpiLaneDirection> createPath(List<String> names,
                                                                                     List<LaneDirection> first)

Creates a path starting at the provided lanes and moving downstream for as long as no lane finds a loop (on to any of the lanes) and there's a unique link all lanes have downstream. The length and speed limit are taken from the first lane.

Parameters:

names - List<String>; lane names

first - List<LaneDirection>; first lanes

Returns:

GraphPath<KpiLaneDirection> path

Throws:

org.opentrafficsim.core.network.NetworkException - when a lane does not have any set speed limit

createSingleLanePath

public static GraphPath<org.opentrafficsim.kpi.sampling.KpiLaneDirection> createSingleLanePath(String name,
                                                                                               LaneDirection lane)
                                                                                        throws org.opentrafficsim.core.network.NetworkException

Creates a single-lane path.

Parameters:

name - String; name

lane - LaneDirection; lane

Returns:

GraphPath<KpiLaneDirection> path

Throws:
