## speed

Speed

* Description: instantaneous speed
* Format: numeric
* Unit: km/h
* Decimal places: 2
  * Data processed by mobway will always have up to 2 decimal places. However, the precision of the original data depends on the automaker. The data may have fewer than 2 decimal places when it ends in 0 due to the automatic formatting of the float type
* Range: 0 to 400 km/h
  * The speed range was defined based on the maximum value that vehicles connected to mobway can reach, including a safety margin
  * Data outside this range is considered erroneous
  * The value is replaced with a null value
  * A flag is generated indicating the error and the original value, in the following format:

```json theme={null}
{
  "speed": {
    "value": 512.54,
    "flag": "out of range"
  }
}
```

* Maximum variation: 50 km/h per second
  * The maximum speed variation was defined based on the maximum acceleration that vehicles connected to mobway can reach, including a safety margin
  * Data with variation above the limit compared to the previous data point is considered erroneous
  * The value is replaced with a null value
  * A flag is generated indicating the error and the original value, in the following format:

```json theme={null}
{
  "speed": {
    "value": 104.17,
    "flag": "variation out of limit"
  }
}
```

* Missing data
  * A flag is generated indicating that the original data was missing, in the following format:

```json theme={null}
{
  "speed": {
    "flag": "missing data"
  }
}
```

* Example:

```json theme={null}
{
  "speed": 78.45
}
```
