class [DistanceDrivenEvaluator](classsimulation__framework_1_1evaluator_1_1DistanceDrivenEvaluator.md#classsimulation__framework_1_1evaluator_1_1DistanceDrivenEvaluator)

Definition of [DistanceDrivenEvaluator](classsimulation__framework_1_1evaluator_1_1DistanceDrivenEvaluator.md#classsimulation__framework_1_1evaluator_1_1DistanceDrivenEvaluator) class to To fulfill this we want to implement a KPI evaluator that aggregates the distance driven by the ego vehicle over the course of the simulation.

**Inherits from**:

- [simulation\_framework::core::kpi::IKpi< osi3::GroundTruth >](classsimulation__framework_1_1core_1_1kpi_1_1IKpi.md#classsimulation__framework_1_1core_1_1kpi_1_1IKpi)
