### <a name="SemiAxisLength"></a>SemiAxisLength
This DE indicates the horizontal position confidence value which represents the estimated absolute position accuracy, in one of the axis direction as defined in a shape of ellipse with a
confidence level of 95 %.
The value shall be set to:
- 'n (n > 0 and n < 4 094)' if the accuracy is equal to or less than n * 0,01 metre,
- '4 094' if the accuracy is out of range, i.e. greater than 4,093 m,
- '4 095' if the accuracy information is unavailable.
**Categories:** GeoReference Information
**Revision:** _Description revised in V2.1.1_
NOTE: The fact that a position coordinate value is received with confidence value 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 position coordinate value may be valid and used by the application.
If a position coordinate value is received and its confidence value is set to 'outOfRange(4094)', it means that
the position coordinate value is not valid and therefore cannot be trusted. Such value is not useful
for the application.

This DE indicates traffic rules that apply to vehicles at a certain position.
- '0' - if overtaking is prohibited for all vehicles,
- '1' - if overtaking is prohibited for trucks,
- '2' - if vehicles should pass to the right lane,
- '3' - if vehicles should pass to the left lane.

### <a name="TrailerPresenceInformation"></a>TrailerPresenceInformation
This DE provides information about the presence of a trailer.
- 0 'noTrailerPresent' - to indicate that no trailer is present, i.e. either the vehicle is physically not enabled to tow a trailer or it has been detected that no trailer is present.
- 1 'trailerPresentWithKnownLength' - to indicate that a trailer has been detected as present and the length is included in the vehicle length value.
- 2 'trailerPresentWithUnknownLength' - to indicate that a trailer has been detected as present and the length is not included in the vehicle length value.
- 3 'trailerPresenceIsUnknown' - to indicate that information about the trailer presence is unknown, i.e. the vehicle is physically enabled to tow a trailer but the detection of trailer presence/absence is not possible.
- 4 'unavailable' - to indicate that the information about the presence of a trailer is not available, i.e. it is neither known whether the vehicle is able to tow a trailer
nor the detection of trailer presence/absence is possible.

### <a name="TrajectoryInterceptionProbability"></a>TrajectoryInterceptionProbability
This DE defines the probability that the ego trajectory intercepts with any other object's trajectory on the road.
- 'n (n ≥ 0 and n ≤ 50)' to indicate the actual probability,
- '63': to indicate that the information is unavailable.
**Categories:** Kinematic information

### <a name="TrajectoryInterceptionConfidence"></a>TrajectoryInterceptionConfidence
This DE defines the confidence level of the trajectoryInterceptionProbability.
- '0' - to indicate confidence level less than 50 %,
- '1' - to indicate confidence level greater than or equal to 50 % and less than 70 %,
- '2' - to indicate confidence level greater than or equal to 70 % and less than 90 %,

### <a name="TransmissionInterval"></a>TransmissionInterval
This DE represents the time interval between two consecutive message transmissions.
**Categories:** Basic information
NOTE: this DE is kept for backwards compatibility reasons only. It is recommended to use the [**DeltaTimeMilliSecondPos**](#DeltaTimeMilliSecondPos) instead.

### <a name="TurningDirection"></a>TurningDirection
- 'left' for turning to te left.

### <a name="TurningRadius"></a>TurningRadius
This DE represents the smallest circular turn (i.e. U-turn) that the vehicle is capable of making.
- 'n (n > 0 and n < 254)' to indicate the applicable value is equal to or less than n x 0,4 metre, and greater than (n-1) x 0,4 metre,
- '254' to indicate that the turning radius is greater than 253 x 0,4 metre = 101.2 metres,
- '255' to indicate that the information is unavailable.
For vehicle with tracker, the turning radius applies to the vehicle only.
**Categories:** Vehicle information
