Evaluation of mapping accuracy performance on the Sequence 4 dataset, focusing on marking and lane accuracy metrics (APE).

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Mapping Accuracy Evaluation |
| Dataset (including any stated split) | Sequence 4 |
| Metric | Marking APE |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 7 of 7 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Marking APE](<https://www.sota2.com/research/sota/mapping-accuracy-evaluation-on-sequence-4.md?metric=Marking%20APE>): Lower is better; unit: SCALAR.

- [Lane APE](<https://www.sota2.com/research/sota/mapping-accuracy-evaluation-on-sequence-4.md?metric=Lane%20APE>): Lower is better; unit: SCALAR.
