An apparatus configured to generate a transition variability index related to autonomous driving, the apparatus comprising processing circuitry and at least one memory including computer program code instructions, the computer program code instructions configured to, when executed by the processing circuitry, cause the apparatus to:
- calculate a transition variability index that comprises first variability data associated with a first degree of variability in relation to transition of vehicles from respective autonomous levels while traveling proximate a first spatial reference point during different intervals of time, and second variability data associated with a second degree of variability in relation to transition of vehicles from respective autonomous levels while traveling along proximate a second spatial reference point during the different intervals of time;
- prioritize updating of transition data associated with one of the first and second spatial reference points relative to another one of the first and second spatial reference points based on a comparison between the first variability data for the first spatial reference point and the second variability data for the second spatial reference point;
- and
- encode the transition data that has been updated for the one of the first and second spatial reference points in a database to facilitate autonomous driving proximate the one of the first and second spatial reference points.
