Properties
| Name | Type | Required | Description |
|---|---|---|---|
doNotUse1 | integer (0–31, default: 0, int8) | No | Always set to 0 and carries no meaning. Legacy field maintained for backward compatibility. |
frameType | string (one of: unknown, advisory, roadSignage, commercialSignage) | Yes | The frameType data element provides the type of message to follow in the rest of the message frame structure. The following frame types are supported: - unknown - advisory - roadSignage - commercialSignage |
msgId | any | Yes | |
startYear | integer (0–4095, int32) | No | The V2X year consists of integer values from zero to 4095 representing the year according to the Gregorian calendar date system. The value of zero shall represent an unknown value. |
startTime | integer (0–527040, int32) | Yes | Start time expresses the number of elapsed minutes of the current year in the time system being used (typically UTC time). The value 527040 shall be used for invalid. |
durationTime | integer (0–32000, int16) | Yes | The duration, in units of whole minutes, that a object persists for. A value of 32000 means that the object persists forever. The range 0..32000 provides for about 22.2 days of maximum duration. |
priority | integer (0–7, int8) | Yes | The relative importance of the sign, on a scale from zero (least important) to seven (most important). |
doNotUse2 | integer (0–31, default: 0, int8) | No | Always set to 0 and carries no meaning. Legacy field maintained for backward compatibility. |
regions | array | Yes | The data frame is used to support the cross-cutting need in many V2X messages to describe arbitrary spatial areas (polygons, boundary lines, and other basic shapes) required by various message types in a small message size. This data frame can describe a complex path or region of arbitrary size using either one of the two supported node offset methods (XY offsets or LL offsets) or using simple geometric projections. |
doNotUse3 | integer (0–31, default: 0, int8) | No | Always set to 0 and carries no meaning. Legacy field maintained for backward compatibility. |
doNotUse4 | integer (0–31, default: 0, int8) | No | Always set to 0 and carries no meaning. Legacy field maintained for backward compatibility. |
content | any | Yes | |
contentNew | any | No | It contains information that extends the original traveler data frame to enable addition of future entities. Friction information is the first entity included in the new part three content. |
