Evaluation of Lane line mapping performance on the 'Sequence 4 Long \>1000 m' subset, measured using Average Positional Error (APE) for markings and lanes.

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 | Lane line mapping |
| Dataset (including any stated split) | Sequence 4 Long \>1000 m |
| Metric | APE (Lanes) |
| 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

- [APE (Lanes)](<https://www.sota2.com/research/sota/lane-line-mapping-on-sequence-4-long-1000-m.md?metric=APE%20(Lanes)>): Lower is better; unit: SCALAR.

- [APE (Markings)](<https://www.sota2.com/research/sota/lane-line-mapping-on-sequence-4-long-1000-m.md?metric=APE%20(Markings)>): Lower is better; unit: SCALAR.
