Method Summary

Modifier and Type	Method	Description
static GraphCrossSection<KpiLaneDirection>	createCrossSection(String name, DirectedLanePosition lanePosition)	Creates a cross section at the provided lane and position.
static GraphCrossSection<KpiLaneDirection>	createCrossSection(List<String> names, List<KpiLaneDirection> lanes, List<Length> positions, Speed speed)	Creates a cross section.
static GraphCrossSection<KpiLaneDirection>	createCrossSection(List<String> names, DirectedLinkPosition linkPosition)	Creates a cross section at the provided link and position.
static GraphPath<KpiLaneDirection>	createPath(String name, LaneDirection first)	Creates a path starting at the provided lane and moving downstream until a dead-end, split, or loop.
static GraphPath<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.
static GraphPath<KpiLaneDirection>	createSingleLanePath(String name, LaneDirection lane)	Creates a single-lane path.

Method Details

createPath

public static GraphPath<KpiLaneDirection> createPath(String name, LaneDirection first) throws 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:

NetworkException - when the lane does not have any set speed limit

createPath

public static GraphPath<KpiLaneDirection> createPath(List<String> names, List<LaneDirection> first) throws NetworkException

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:

NetworkException - when a lane does not have any set speed limit

createSingleLanePath

public static GraphPath<KpiLaneDirection> createSingleLanePath(String name, LaneDirection lane) throws NetworkException

Creates a single-lane path.

Parameters:

name - String; name

lane - LaneDirection; lane

Returns:

GraphPath<KpiLaneDirection> path

Throws:

NetworkException - when a lane does not have any set speed limit

createCrossSection

public static GraphCrossSection<KpiLaneDirection> createCrossSection(String name, DirectedLanePosition lanePosition) throws NetworkException

Creates a cross section at the provided lane and position.

Parameters:

name - String; name

lanePosition - DirectedLanePosition; lane position

Returns:

GraphCrossSection<KpiLaneDirection> cross section

Throws:

NetworkException - when the lane does not have any set speed limit

createCrossSection

public static GraphCrossSection<KpiLaneDirection> createCrossSection(List<String> names, DirectedLinkPosition linkPosition) throws NetworkException

Creates a cross section at the provided link and position.

Parameters:

names - List<String>; lane names

linkPosition - DirectedLinkPosition; link position

Returns:

GraphCrossSection<KpiLaneDirection> cross section

Throws:

NetworkException - when a lane does not have any set speed limit

createCrossSection

public static GraphCrossSection<KpiLaneDirection> createCrossSection(List<String> names, List<KpiLaneDirection> lanes, List<Length> positions, Speed speed)

Creates a cross section.

Parameters:

names - List<String>;; names

lanes - List<KpiLaneDirection>;; lanes

positions - List<Length>; positions

speed - Speed; speed

Returns:

GraphCrossSection<KpiLaneDirection>; cross section
