### <a name="TemporaryID"></a>TemporaryID
This is the 4 octet random device identifier, called the TemporaryID. When used for a mobile OBU device, this value
 will change periodically to ensure the overall anonymity of the vehicle, unlike a typical wireless or wired 802 device ID.
 Because this value is used as a means to identify the local vehicles that are interacting during an encounter, it is used in
 the message set. Other devices, such as infrastructure (RSUs), may have a fixed value for the temporary ID value. See
 also [**StationId**](#StationId) which is used in other deployment regions.

&nbsp;&nbsp;&nbsp;&nbsp;**Revision:** _V1.3.1_

>>>
NOTE:&emsp;The circumstances and times at which various DSRC devices (notably OBUs) create and change their current
        Temporary ID is a complex application level topic. It should be noted that the Temporary ID is not the same as a device
        MAC value, although when used as a means to uniquely identify a device, both have many common properties. It should
        further be noted that the MAC value for a mobile OBU device (unlike a typical wireless or wired 802 device) will
        periodically change to a new random value to ensure the overall anonymity of the vehicle.

### <a name="ThrottleConfidence"></a>ThrottleConfidence
This DE is used to provide the 95% confidence level for the currently reported
 value of DE [**Throttle**](#Throttle), taking into account the current calibration and precision of the sensor(s) used to measure and/or
 calculate the value. This data element is only to provide information on the limitations of the sensing system, not to
 support any type of automatic error correction or to imply a guaranteed maximum error. This data element should not be
 used for fault detection or diagnosis, but if a vehicle is able to detect a fault, the confidence interval should be increased
 accordingly. If a fault that triggers the MIL is of a nature to render throttle performance unreliable, then ThrottleConfidence
 should be represented as "notEquipped."

### <a name="Velocity"></a>Velocity
This DE represents the velocity of an object, typically a vehicle speed or the recommended speed of
 travel along a roadway, expressed in unsigned units of 0.02 meters per second. When used with motor vehicles it may be
 combined with the transmission state to form a data frame for use. A value of 8191 shall be used when the speed is
 unavailable. Note that Velocity as used here is intended to be a scalar value and not a vector.

 The value 8191 indicates that velocity is unavailable

&nbsp;&nbsp;&nbsp;&nbsp;**Unit:** _0.02 m/s_

### <a name="ZoneLength"></a>ZoneLength
This DE is used to provide an estimated distance from the stop bar, along the lane
 centerline back in the lane to which it pertains. It is used in various ways to relate this distance value. When used with
 clearance zones, it represents the point at which the driver can successfully execute the connection maneuver. It is used
 in the Clearance Maneuver Assist data frame to relate dynamic data about the lane. It is also used to relate the distance
 from the stop bar to the rear edge of any queue. It is further used within the context of a vehicle's traveling speed to
 advise on preferred dynamic approach speeds.

 0 = unknown,
 The value 10000 to be used for Distances >=10000 m (e.g. from known point to another point along a
 known path, often against traffic flow direction when used for measuring queues)

## 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.*

```asn1
ConnectionManeuverAssist-addGrpC ::=	SEQUENCE {
  itsStationPosition ItsStationPositionList OPTIONAL,
  ...
}
```

### <a name="ConnectionTrajectory-addGrpC"></a>ConnectionTrajectory-addGrpC
The data frame "ConnectionTrajectory-addGrpC" 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.

* _nodes_ of type [**NodeSetXY**](ETSI-ITS-DSRC.md#NodeSetXY) <br>
  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.

* _connectionID_ of type [**LaneConnectionID**](ETSI-ITS-DSRC.md#LaneConnectionID) <br>
  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".

&nbsp;&nbsp;&nbsp;&nbsp;**Revision:** _V1.3.1_

>>>
NOTE:&emsp;"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.

### <a name="IntersectionState-addGrpC"></a>IntersectionState-addGrpC
The data frame "IntersectionState-addGrpC" 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 within 
   the "IntersectionState-addGrpC" data element (see [ISO TS 19091] G.5.1.9).
 - For more complex signal requests, the SignalRequestMessage/SignalStatusMessage messages are to be used.

* _activePrioritizations_ of type [**PrioritizationResponseList**](#PrioritizationResponseList) 	OPTIONAL<br>
  list of Prioritizations.


&nbsp;&nbsp;&nbsp;&nbsp;**Categories:** Infrastructure information

### <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 SAE J2735 for other messages.

* _maxVehicleHeight_ of type [**VehicleHeight**](ETSI-ITS-DSRC.md#VehicleHeight)  OPTIONAL<br>
  maximum allowed vehicle height

* _maxVehicleWeight_ of type [**VehicleMass**](ETSI-ITS-CDD.md#VehicleMass)    OPTIONAL<br>
  maximum allowed vehicle mass


&nbsp;&nbsp;&nbsp;&nbsp;**Categories:** Infrastructure information

```

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

* _signalHeadLocations_ of type [**SignalHeadLocationList**](#SignalHeadLocationList) 	OPTIONAL<br>
  list of geo positions


&nbsp;&nbsp;&nbsp;&nbsp;**Categories:** Infrastructure information 

&nbsp;&nbsp;&nbsp;&nbsp;**Revision:** _V1.3.1_

```

### <a name="MovementEvent-addGrpC"></a>MovementEvent-addGrpC
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.

* _stateChangeReason_ of type [**ExceptionalCondition**](#ExceptionalCondition)  OPTIONAL<br>
  reason code


&nbsp;&nbsp;&nbsp;&nbsp;**Categories:** Infrastructure information 

&nbsp;&nbsp;&nbsp;&nbsp;**Revision:** _V1.3.1_

```

### <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.

* _ptvRequest_ of type [**PtvRequestType**](#PtvRequestType)   OPTIONAL<br>
  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.

* _nodeLink_ of type [**NodeLink**](#NodeLink)         OPTIONAL<br>
  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).

* _node_ of type [**Node**](#Node)             OPTIONAL<br>
  defines an identifier of this node.

### <a name="Position3D-addGrpC"></a>Position3D-addGrpC
The data frame "Position3D-addGrpC" includes the altitude data element defined in the common data dictionary [ETSI CDD].

* _altitude_ of type [**Altitude**](ETSI-ITS-CDD.md#Altitude) <br>
* elevation<br>
  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 (see [ISO TS 19091] G.5.1.8).
                     "Position3D-addGrpC" extends the "DF_Position3D" using the regional extension framework as defined in [ISO TS 19091] G.7.7.

### <a name="RestrictionUserType-addGrpC"></a>RestrictionUserType-addGrpC
The data frame "RestrictionUserType-addGrpC" 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.

* _emission_ of type [**EmissionType**](#EmissionType)  OPTIONAL<br>
  restriction baesed on emission.

* _fuel_ of type [**FuelType**](ETSI-ITS-DSRC.md#FuelType)      OPTIONAL<br>
  restriction baesed on fuel.

### <a name="RequestorDescription-addGrpC"></a>RequestorDescription-addGrpC
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.

* _fuel_ of type [**FuelType**](ETSI-ITS-DSRC.md#FuelType)       OPTIONAL<br>
  fuel used by vehicle.

### <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.

* _synchToSchedule_ of type [**DeltaTime**](ETSI-ITS-DSRC.md#DeltaTime)       OPTIONAL<br>
  DeltaTime.

* _rejectedReason_ of type [**RejectedReason**](#RejectedReason)  OPTIONAL<br>
  RejectedReason.

@Note: The "PrioritizationResponseStatus" provides optionally the reason for prioritization response rejection.

 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.
