### <a name="CauseCodeV2"></a>CauseCodeV2
 This DF is an alternative representation of the cause code value of a traffic event. 

 It includes the following components: 


 The semantics of the entire DF are completely defined by the component causeCode. The interpretation of the subCauseCode may 
 provide additional information that is not strictly necessary to understand the causeCode itself, and is therefore optional.

Fields:
* ccAndScc [**CauseCodeChoice**](#CauseCodeChoice) <br>
  the main cause of a detected event. Each choice is of a different type and represents the sub cause code.



&nbsp;&nbsp;&nbsp;&nbsp;**Categories**: Traffic information

### <a name="CenDsrcTollingZone"></a>CenDsrcTollingZone
 The DF describes the position of a CEN DSRC road side equipment.

 It includes the following components:

Fields:
* protectedZoneLatitude [**Latitude**](#Latitude) <br>
  the latitude of the CEN DSRC road side equipment.


* protectedZoneLongitude [**Longitude**](#Longitude) <br>
