## Data Elements:
### <a name="ConnectionManeuverAssist-addGrpC"></a>ConnectionManeuverAssist-addGrpC
This Element adds positioning support from the infrastructure to the vehicle.
* _itsStationPosition_ of type [**ItsStationPositionList**](#ItsStationPositionList) OPTIONAL<br>
* itsStationPositions<br>
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.*

### <a name="ConnectionTrajectory-addGrpC"></a>ConnectionTrajectory-addGrpC
The data frame âConnectionTrajectory-addGrpCâ 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 G.8.2.5.
ânodesâ 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.
âconnectionIDâ defines the identifier of an allowed âmaneuverâ (e.g. ingress / egress relation). A generic
Lane offers one or more allowed âmaneuversâ, therefore the trajectory is reference to the related
âmaneuverâ.
Note: "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.

/ ConnectionTrajectory:
The data frame âConnectionTrajectory-addGrpCâ defines the trajectory for travelling e.g. through the
conflict area of an intersection. The trajectory is defined by two or more nodes. In the example in Figure
G.1, the first node position of the trajectory (T2-1) is matching to the node of the ingress lane towards
the conflict zone (L2-1), and the ending node (T2-6) and the first node of the connected egress share the
same position (L6-1). Additionally, the data frame âNodeLinkâ (G.5.2.3) is used to define a clear relation
between the trajectory endpoint and the connected lane point.

### <a name="IntersectionState-addGrpC"></a>IntersectionState-addGrpC
The data frame âIntersectionState-addGrpCâ 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.
â 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 within the âIntersectionState-addGrpCâ data
element (see G.5.1.9).
â For more complex signal requests, the SignalRequestMessage/SignalStatusMessage messages are
be used.
regional / IntersectionState:
This data element includes additional data content âIntersectionState-addGrpCâ defined in this profile
(see G.5.1.3,). The content is included using the regional extension framework as defined in G.7.4.

### <a name="LaneAttributes-addGrpC"></a>LaneAttributes-addGrpC
Lanes may have limitations regarding vehicle height (e.g. due to a tunnel) and vehicle weight (e.g. due to
a bridge). To indicate these limitations, two data elements are added which are already defined in J2735
for other messages.

### <a name="MapData-addGrpC"></a>MapData-addGrpC
The data frame âMapData-addGrpCâ 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.

(eventState). User acceptance is expected to increase if the reason for sudden changes in timing
parameters is communicated to them.

### <a name="NodeAttributeSet-addGrpC"></a>NodeAttributeSet-addGrpC
The data frame "NodeAttributeSet-addGrpC" defines additional attributes to support public transport
and to enable a simple way of defining lane links.
myCommittee | 13.06.2019 | 19017046,Siemens Mobility GesmbH,Dipl.-Ing. Thomas Ritter
âptvRequestâ 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.
ânodeLinkâ 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 (G.8.2.7) and the linking of trajectories in the conflict zone to lanes (see
example G.8.2.5).
ânodeâ defines an identifier of this node.

extension. The âaltitudeâ data element is defined in âPosition3D-addGrpCâ of this profile (see G.5.1.8).
âPosition3D-addGrpCâ extends the âDF_Position3Dâ using the regional extension framework as defined
in G.7.7.

### <a name="RestrictionUserType-addGrpC"></a>RestrictionUserType-addGrpC
The data frame âRestrictionUserType-addGrpCâ 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.
regional / RestrictionUserType:
This data element includes additional data content âRestrictionUserType-addGrpCâ defined in this
profile (see G.5.1.9). The content is included using the regional extension framework as defined in G.7.8.

### <a name="SignalStatusPackage-addGrpC"></a>SignalStatusPackage-addGrpC
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. The "PrioritizationResponseStatus" provides optionally the reason for
prioritization response rejection.

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.
