Evaluation of sidewalk width estimation performance using data from the Washington D.C. dataset, typically measured using Mean Absolute Error (MAE) and error thresholds (e.g., \<0.25m, \<0.50m).

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 | Sidewalk width estimation |
| Dataset (including any stated split) | Washington D.C. |
| Metric | MAE |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 4 of 4 |
| 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

- [MAE](<https://www.sota2.com/research/sota/sidewalk-width-estimation-on-washington-d-c.md?metric=MAE>): Lower is better; unit: SCALAR.

- [Accuracy (\<0.25 m)](<https://www.sota2.com/research/sota/sidewalk-width-estimation-on-washington-d-c.md?metric=Accuracy%20(%3C0.25%20m)>): Higher is better; unit: PERCENT.

- [Accuracy (\<0.50 m)](<https://www.sota2.com/research/sota/sidewalk-width-estimation-on-washington-d-c.md?metric=Accuracy%20(%3C0.50%20m)>): Higher is better; unit: PERCENT.
