Derived data

Current consensus

Derived data are data created as a result of processing that involves steps other than or in addition to direct retrieval and validation of information from raw data.

Explanation

Derived data are obtained by transforming raw data into more directly usable data through, for instance: data fusion, filtering, classification, and reduction. They typically contain derived measures (such as, for instance, time-headway, which derives from both longitudinal speed and headway), and performance indicators (PI), referring to time- and location-based segments such as particular events.
