We drove the detours the map predicted.
On 2026-11-01 arcroad drove modelled places on Hyderabad's west corridor with a GPS recording. Of 5 direction(s) that could be compared with the model, 5 matched it within the tolerance fixed before the drive. Every pass is listed, including the ones that did not count.
Every pass
| Place | Direction | Straight across | Model | Driven | Time | Verdict | Evidence level | Evidence kinds |
|---|---|---|---|---|---|---|---|---|
| T2 | A → B | — | — | 3.08 km | 10.6 min | No model route to compare | Modelled | S · candidate |
| T2 | B → A | — | — | 3.89 km | 13.5 min | No model route to compare | Modelled | S · candidate |
| S16 | B → A | 19 m | 2.38 km | 2.30 km | 9.0 min | Matched the model | Driven by arcroad | S · candidate |
| S18 | A → B | 13 m | 1.57 km | 1.58 km | 3.2 min | Matched the model | Driven by arcroad | S · candidate |
| S18 | B → A | 13 m | 1.38 km | 1.55 km | 11.5 min | Matched the model | Driven by arcroad | S+P · corroborated |
| S23 | B → A | 20 m | — | 11.34 km | 13.1 min | No model route to compare | Modelled | S · candidate |

| S24 | B → A | 20 m | 10.49 km | 11.60 km | 25.2 min | Matched the model | Driven by arcroad | S · candidate |
Evidence kinds: S a timed drive, P a usable photo at the place during the pass, R a repeat pass. One kind is a candidate, two corroborated, three with a photo or an official record triangulated. Times include waits at signals and U-turn queues (Sunday afternoon and evening).
Rejected passes
- S17 B → A: driven shorter than the straight line: not a crossing
Visited but not scored
- S01: reached within 4 m of one side and 15 m of the other; the gate needs 10 m on both, so no pass is counted
- S04: reached within 5 m of one side and 15 m of the other; no pass counted
- S11: visited (geotagged photos 18:37-18:39) while the GPS recording was stopped; no measured pass
- S14: visited (geotagged photos 19:06-19:07) while the GPS recording was stopped; no measured pass
- S12: not reached
Limits
- One day, one driver, one car. A single pass per direction is a candidate under the triangulation rule until repeated or photographed.
- Phone GPS at 1 Hz; distances carry roughly ±50 m of noise on a 1-3 km loop.
- S23 and S24 lie on the Outer Ring Road, an access-controlled expressway: turning round there by design needs an interchange or service road. Road class is not yet separated in the figures.
- Times include waits at signals and U-turn queues on a Sunday afternoon and evening; weekday peaks will differ.
- Raw tracks and photos are private; only these per-pass summaries are published.
How this was scored
Thresholds were written before the drive and are not changed after seeing results. A drive matches when it is within the larger of 150 m or 25% of the model's distance. The code is public: pipeline/fieldscore.py, pipeline/groundtruth.py, pipeline/evidence.py; docs/ENGINE.md triangulation rule. The raw recordings stay private; only these per-pass numbers are published. See the places on the 3D map · arcroad home
