### <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="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.
