### <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).

**Revision**: _Description revised in V2.1.1_
>>>
NOTE: in practice this means that the position is counted from "inside" to "outside" no matter which traffic practice is used.

### <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`.

### <a name="PtActivationData"></a>PtActivationData
This DE is used for various tasks in the public transportation environment, especially for controlling traffic
signal systems to prioritize and speed up public transportation in urban area (e.g. intersection "_bottlenecks_").
The traffic lights may be controlled by an approaching bus or tram automatically. This permits "_In Time_" activation
of the green phase, will enable the individual traffic to clear a potential traffic jam in advance. Thereby the
approaching bus or tram may pass an intersection with activated green light without slowing down the speed due to
traffic congestion. Other usage of the DE is the provision of information like the public transport line number
or the schedule delay of a public transport vehicle.
