### <a name="LanePosition"></a>LanePosition
 This DE indicates a transversal position on the carriageway at a specific longitudinal position, in resolution of lanes of the carriageway. 

 For right-hand traffic roads, the value shall be set to:
 - `-1` if the position is off, i.e. besides the road.
 - `0` if the position is on the inner hard shoulder, i.e. the hard should adjacent to the leftmost lane.
 - `n (n >0 and n < 14)`, if the position is on the n-th driving lane counted from the leftmost lane to the rightmost lane of a specific traffic direction. 
 - `14` if the position is on the outer hard shoulder, i.e. the hard should adjacent to rightmost lane (if present).

 For left-hand traffic roads, the value shall be set to:
 - `-1` if the position is off, i.e. besides the road.
 - `0` if the position is on the inner hard shoulder, i.e. the hard should adjacent to the rightmost lane.
 - `n (n >0 and n < 14)`, if the position is on the n-th driving lane counted from the rightmost lane to the leftmost lane of a specific traffic direction. 
 - `14` if the position is on the outer hard shoulder, i.e. the hard should adjacent to leftmost lane (if present).


 If the carriageway allows only traffic in one direction (e.g. in case of dual or multiple carriageway roads), the position is counted from the physical border of the carriageway. 
 If the carriageway allows traffic in both directions and there is no physical delimitation between traffic directions (e.g. on a single carrriageway road), 
 the position is counted from the legal (i.e. optical) separation between traffic directions (horizontal marking).

### <a name="PositionOfOccupants"></a>PositionOfOccupants
 This DE indicates whether a passenger seat is occupied or whether the occupation status is detectable or not.
 
 The number of row in vehicle seats layout is counted in rows from the driver row backwards from front to the rear
 of the vehicle.
 The left side seat of a row refers to the left hand side seen from vehicle rear to front.
 Additionally, a bit is reserved for each seat row, to indicate if the seat occupation of a row is detectable or not,
 i.e. `row1NotDetectable (3)`, `row2NotDetectable(8)`, `row3NotDetectable(13)` and `row4NotDetectable(18)`.
 Finally, a bit is reserved for each row seat to indicate if the seat row is present or not in the vehicle,
 i.e. row1NotPresent `(4)`, row2NotPresent `(9)`, `row3NotPresent(14)`, `row4NotPresent(19)`.
 
 When a seat is detected to be occupied, the corresponding seat occupation bit shall be set to `1`.
 For example, when the row 1 left seat is occupied, `row1LeftOccupied(0)` bit shall be set to 1.
 When a seat is detected to be not occupied, the corresponding seat occupation bit shall be set to `0`.
 Otherwise, the value of seat occupation bit shall be set according to the following conditions:
 - If the seat occupation of a seat row is not detectable, the corresponding bit shall be set to `1`.
   When any seat row not detectable bit is set to `1`, all corresponding seat occupation bits of the same row
   shall be set to `1`.
 - If the seat row is not present, the corresponding not present bit of the same row shall be set to `1`.
   When any of the seat row not present bit is set to `1`, the corresponding not detectable bit for that row
   shall be set to `1`, and all the corresponding seat occupation bits in that row shall be set to `0`.

NOTE: The fact that a position coordinate value is received with confidence set to 'unavailable(4095)'
 can be caused by several reasons, such as:
 - the sensor cannot deliver the accuracy at the defined confidence level because it is a low-end sensor,
 - the sensor cannot calculate the accuracy due to lack of variables, or
 - there has been a vehicle bus (e.g. CAN bus) error.
 In all 3 cases above, the reported position coordinate value may be valid and used by the application.
 If a position coordinate value is received and its confidence is set to 'outOfRange(4094)', it means that
 the reported position coordinate value is not valid and therefore cannot be trusted. Such value is not useful
 for the application.

NOTE: 1: The fact that a steering wheel angle value is received with confidence set to 'unavailable(127)'
 can be caused by several reasons, such as:
 - the sensor cannot deliver the accuracy at the defined confidence level because it is a low-end sensor,
 - the sensor cannot calculate the accuracy due to lack of variables, or
 - there has been a vehicle bus (e.g. CAN bus) error.
 In all 3 cases above, the reported steering wheel angle value may be valid and used by the application.

### <a name="YawRateConfidence"></a>YawRateConfidence
 This DE denotes the absolute accuracy range for reported yaw rate value for a confidence level of 95%.
 
 The value shall be set to:
 - `0` indicates that the accuracy is equal to or less than 0,01 degree/second.
 - `1` indicates that the accuracy is equal to or less than 0,05 degrees/second.
 - `2` indicates that the accuracy is equal to or less than 0,1 degree/second.
 - `3` indicates that the accuracy is equal to or less than 1 degree/second.
 - `4` indicates that the accuracy is equal to or less than 5 degrees/second.
 - `5` indicates that the accuracy is equal to or less than 10 degrees/second.
 - `6` indicates that the accuracy is equal to or less than 100 degrees/second.
 - `7` indicates that the accuracy is out of range, i.e. greater than 100 degrees/second.
 - `8` indicates that the accuracy information is unavailable
 
 NOTE: The fact that a yaw rate value is received with confidence set to `unavailable(8)` can be caused by
 several reasons, such as:
 - the sensor cannot deliver the accuracy at the defined confidence level because it is a low-end sensor,
 - the sensor cannot calculate the accuracy due to lack of variables, or
 - there has been a vehicle bus (e.g. CAN bus) error.
 In all 3 cases above, the reported yaw rate value may be valid and used by the application.
 
 If a yaw rate value is received and its confidence is set to `outOfRange(7)`, it means that the reported
 yaw rate value is not valid and therefore cannot be trusted. Such value is not useful the application.

      and greater than (n-1) x 0,01 degrees/s.
 - `n (n > 0 and n < 32 766)` to indicate that the rotation is anti-clockwise (i.e. to the left) and is equal to or less than n x 0,01 degrees/s, 
      and greater than (n-1) x 0,01 degrees/s.
 - `32 766` to indicate that the yaw rate is greater than 327.65 degrees/second to the left.
 - `32 767` to indicate that the information is not available.
