* This DF adds positioning support from the infrastructure to the vehicle.
*
* @field itsStationPositions: defines a list of ITS stations (e.g. vehicles) and their corresponding position on
* the driving lane as defined in the lane topology of the MapData message or the GNSS position
* deviation of the ITS Station from the high precision reference position in X/Y coordinates. It
* enables accurate, real-time positioning support to the moving ITS entities by the infrastructure.*
*
ConnectionManeuverAssist-addGrpC ::= SEQUENCE {
itsStationPosition ItsStationPositionList OPTIONAL,
...
}
* This DF defines the trajectory for travelling through the conflict area of an intersection and connects
* e.g an ingress with an egress lane. The trajectory is defined by two or more nodes.
* The starting node overlaps e.g. with the node of the ingress lane towards the
* conflict zone. The ending node overlaps e.g. with the first node of the connected egress lane.
* See the example in clause [ISO TS 19091] G.8.2.5.
*
* @field nodes: defines a list of nodes for the trajectory. It defines e.g. a geometric trajectory from an ingressing
* to a connected egressing lane and the X/Y position value of the first node of the trajectory is the same as
* the node of the ingress lane. The X/Y position of the last node is the same as the X/Y position of the first
* node of the egressing lane.
* @field connectionID: defines the identifier of an allowed `maneuver` (e.g. ingress / egress relation).
* A generic Lane offers one or more allowed `maneuvers`, therefore the trajectory is reference to the related `maneuver`.
* @note: @ref Reg-GenericLane allows providing up to 4 connecting trajectories. In case a lane has more than 4 connecting trajectories,
* priority should be given to connecting trajectories of motorized traffic and complex manoeuvres.
*
*
* @category: Infrastructure information
ConnectionTrajectory-addGrpC ::= SEQUENCE {
nodes NodeSetXY,
connectionID LaneConnectionID,
...
}
* This DF defines a list of prioritization responses e.g. public transport acceleration.
* The signal prioritization (e.g. public transport) procedure in this profile follows two strategies.
* - For simple prioritization requests, the CAM/SPAT messages are used.
* This allows the migration of old legal systems towards C-ITS.
* In this case, the CAM message is used to trigger the request towards the traffic light controller.
* The traffic light controller checks the request and broadcasts the status for the priority request with this DF (see [ISO TS 19091] G.5.1.9).
* - For more complex signal requests, the SignalRequestMessage/SignalStatusMessage messages are to be used.
*
* @field activePrioritizations: list of Prioritizations.
*
* @category: Infrastructure information
IntersectionState-addGrpC ::= SEQUENCE {
activePrioritizations PrioritizationResponseList OPTIONAL,
...
}
* Lanes may have limitations regarding vehicle height (e.g. due to a tunnel) and vehicle weight (e.g. due to a bridge).
* @field maxVehicleHeight: maximum allowed vehicle height
* @field maxVehicleWeight: maximum allowed vehicle mass
LaneAttributes-addGrpC ::= SEQUENCE {
maxVehicleHeight VehicleHeight OPTIONAL,
maxVehicleWeight VehicleMass OPTIONAL,
...
}
* This DF defines a list of three-dimensional positions of signal heads in an intersection.
* It enables vehicles to identify the signal head location for optical evaluation of the traffic light.
* Combined with the SPAT/MapData messages, it enables e.g. driving vehicles to enhance safety decision in critical situations.
MapData-addGrpC ::= SEQUENCE {
signalHeadLocations SignalHeadLocationList OPTIONAL,
...
}
* Priority and preemption have a considerable impact to the timing parameters in the SPAT message (eventState).
* User acceptance is expected to increase if the reason for sudden changes in timing parameters is communicated to them.
MovementEvent-addGrpC ::= SEQUENCE {
stateChangeReason ExceptionalCondition OPTIONAL,
...
}
* This DF defines additional attributes to support public transport and to enable a simple way of defining lane links.
*
* @field ptvRequest: defines control types attached to a node on a lane used by public transport for triggering
* the transmission of messages (e.g. prioritization request). It includes control points for public transport prioritization.
* These control points are currently implemented by legacy systems using hardware sensors mounted on the roadside.
* @field nodeLink: defines a link to one or to a set of another node/lane from this node. The nodeLink allows to set a link between specific nodes
* of generic lanes or trajectories. This supports e.g. lane merging/diverging situations ([ISO TS 19091] G.8.2.7) and the linking of trajectories
* in the conflict zone to lanes (see example [ISO TS 19091] G.8.2.5).
* @field node: defines an identifier of this node.
*
* @category: Infrastructure information
NodeAttributeSet-addGrpC ::= SEQUENCE {
ptvRequest PtvRequestType OPTIONAL,
nodeLink NodeLink OPTIONAL,
node Node OPTIONAL,
...
}
* This DF includes the altitude data element defined in the common data dictionary [ETSI CDD].
* @field elevation: the data element is replaced by the ETSI `altitude` data element using the regional extension.
* The `altitude` data element is defined in Position3D-addGrpC of this profile.
* Position3D-addGrpC extends the @ref Position3D using the regional extension framework.
Position3D-addGrpC ::= SEQUENCE {
altitude Altitude,
...
}
* This DF defines the driving restriction based on toxic emission type.
* The meaning of the word `restriction` is ambiguous as it may have a double interpretation, being:
* - only these vehicles are allowed OR
* - these vehicles are not allowed and all others are.
* The former is what is intended by the base standard.
*
* @field emission: restriction baesed on emission.
* @field fuel: restriction baesed on fuel.
RestrictionUserType-addGrpC ::= SEQUENCE {
emission EmissionType OPTIONAL,
fuel FuelType OPTIONAL,
...
}
/**
* Some road authorities like to give priority to vehicles based on the type of fuel they use. In addition,
* electric vehicles may receive priority based on their battery status.
* @field fuel: fuel used by vehicle.
* @field batteryStatus: current batter status of vehicle.
RequestorDescription-addGrpC ::= SEQUENCE {
fuel FuelType OPTIONAL,
batteryStatus BatteryStatus OPTIONAL,
...
}
* The traffic control centre (TCC) may advice a public transport vehicle (e.g. bus) to synchronize his travel time.
* This may happen when, for example, two busses, due to special traffic conditions, are out of schedule.
* The first might be too late, the second too fast. The consequence is that the second is driving
* just behind the first and is empty as all passengers are within the first one. To avoid this often-occurring
* situation, the TCC transmits time synchronization advices to the public transport vehicles using the
* signal status message.
*
* @field synchToSchedule: DeltaTime.
* @field rejectedReason: RejectedReason.
*
* @Note: The @ref PrioritizationResponseStatus provides optionally the reason for prioritization response rejection.
SignalStatusPackage-addGrpC ::= SEQUENCE {
synchToSchedule DeltaTime OPTIONAL,
rejectedReason RejectedReason OPTIONAL,
...
}
* This DF is used to provide real-time positioning information feedback to a specific ITS station
* (e.g. vehicle, pedestrian, bicycle) by infrastructure equipment.
* The position information includes, for example, the driving, crossing lane and/or the X/Y coordinates in relation to
* the reference position of the MapData. The `timeReference` indicates the time stamp of the the
* message (received from an ITS station) for which the positioning feedback has been computed.
*
* @field stationID: unique identifier.
* @field laneID: LaneID.
* @field nodeXY: NodeOffsetPointXY.
* @field timeReference: TimeReference.
*
* @note: The computation of the positioning feedback is out of focus of this standard.

* This DF is used to to identify a node of a lane (waypoint) by its `lane` and node identifier `id`.
*
* The `intersectionID` is used if the referenced lane belongs to an adjacent intersection. If the node
* belongs to a connection trajectory ([ISO TS 19091] G.5.1.2) the `connectionID` is used.
* @field id: unique identifier.
* @field lane: identifier from lane.
