PyANGKernel.GKSuperNode¶

class GKSuperNode¶

A Supernode definition. * Supernodes are used to represent situations in which it is not possible to model the cost of traversing sections and turns using the sum of the individual components; i.e. when the cost of traversing the set of sections and turns is heavily dependent on the movement through them such as at a roundabout, a staggered crossroads, or at a complex junction.

__init__()¶

activeTrajectories()¶

Return type:: .list of GKSuperNodeTrajectory

Returns all the active trajectories. Careful, it does not take Overrides into account.

addNode(iNode)¶

Parameters:: iNode – GKNode

Adds a new node to the Supernode

conflictingTrajectories(scenario, trajectory, conflictTrajectory)¶

Parameters:

scenario – GKGenericScenario
trajectory – GKSuperNodeTrajectory
conflictTrajectory – GKSuperNodeTrajectory

Return type:

bool

Returns if these two trajectories’ cross paths under the given scenario, bothering other vehicles.

entranceSections()¶

Return type:: .list of GKSection

Returns all the sections leading to this Supernode, unfiltered by context.

exitSections()¶

Return type:: .list of GKSection

Returns all the exit sections in this Supernode, unfiltered by context.

getNodes()¶

Return type:: .list of GKNode

Gets all the nodes belonging to this Supernode

getTrajectoriesByDestination(section)¶

Parameters:: section – GKSection
Return type:: .list of GKSuperNodeTrajectory

Returns all the trajectories that have ‘section’ as its exit section.

getTrajectoriesByOrigin(section)¶

Parameters:: section – GKSection
Return type:: .list of GKSuperNodeTrajectory

Returns all the trajectories that have ‘section’ as its entrance section.

getTrajectoryByOD(entranceSection, exitSection)¶

Parameters:

entranceSection – GKSection
exitSection – GKSection

Return type:

GKSuperNodeTrajectory

Returns the trajectory associated to ‘origin’ and ‘destination’ sections in this Supernode.

harmoniousTrajectories(scenario, trajectory, conflictTrajectory)¶

Parameters:

scenario – GKGenericScenario
trajectory – GKSuperNodeTrajectory
conflictTrajectory – GKSuperNodeTrajectory

Return type:

bool

Returns if these two trajectories’ share the initial turning under the given scenario, helping flow.

hasNode(iNode)¶

Parameters:: iNode – GKNode
Return type:: bool

Returns whether a node belongs to a Supernode or not.

hasUserDefinedConflict(trjA, trjB)¶

Parameters:

trjA – GKSuperNodeTrajectory
trjB – GKSuperNodeTrajectory

Return type:

bool

Returns true if there is a user-defined conflict that affects trajectory A caused by trjB.

inactiveTrajectories()¶

Return type:: .list of GKSuperNodeTrajectory

Returns all the inactive trajectories. Careful, it does not take Overrides into account.

innerSections()¶

Return type:: .list of GKSection

Returns all the inner sections in this Supernode, unfiltered by context.

recalculateTrajectories()¶

Function to be called after adding or removing nodes to automatically recalculate the trajectories

removeNode(iNode)¶

Parameters:: iNode – GKNode

Removes the specified node from the Supernode

removeTrajectory(trj)¶

Parameters:: trj – GKSuperNodeTrajectory

Avoid using this. It’s not private because restoring trajectories from older networks might need to erase themselves.

setNodes(nodes)¶

Parameters:: nodes – .list of GKNode

Sets all the nodes belonging to this Supernode

setUserDefinedConflict(affectedTrj, conflictingTrj, active)¶

Parameters:

affectedTrj – GKSuperNodeTrajectory
conflictingTrj – GKSuperNodeTrajectory
active – bool

Activates or deactivates a user-defined conflict in the SuperNode.

hasUserDefinedConflict()

setUserDefinedConflictsActive(active)¶

Parameters:: active – bool

Enable/disable user-defined conflicts for this SuperNode

See also

userDefinedConflictsActive()

trajectories()¶

Return type:: .list of GKSuperNodeTrajectory

Returns all the SuperNodeTrajectories defined for this Supernode, unfiltered by context. Recommended! Filter afterwards using context to consider Geometry configurations and Attribute Overrides.

trajectorySections(scenario, origin, destination)¶

Parameters:

scenario – GKGenericScenario
origin – GKSection
destination – GKSection

Return type:

.list of GKSection

Returns the path for the trajectory defined by ‘origin’ and ‘destination’ sections in this Supernode, as a vector of sections. Context aware (scenario). Null scenario means any.

trajectoryTurnings(scenario, origin, destination)¶

Parameters:

scenario – GKGenericScenario
origin – GKSection
destination – GKSection

Return type:

.list of GKTurning

Returns the path for the trajectory defined by ‘origin’ and ‘destination’ sections in this Supernode, as a vector of turnings. Context aware (scenario). Null scenario means any.

turnings()¶

Return type:: .list of GKTurning

Returns all the turnings in this Supernode, unfiltered by context.

userDefinedConflictsActive()¶

Return type:: bool

Returns true if the user-defined conflicts are active for this SuperNode

See also

setUserDefinedConflictsActive()

userDefinedConflictsFor(trj)¶

Parameters:: trj – GKSuperNodeTrajectory
Return type:: .list of const GKSuperNodeTrajectory

Returns a list with all the user-defined conflicts that affect a given trajectory
