Routes
Route Coverage
| ATLAS stops matched by GTFS routes | 42,583 / 54,945 | 77.5% |
| OSM stops with routes coverage | 36,863 | 75.1% |
ATLAS coverage here is stop-side route coverage. The GTFS mapping block below reports the separate GTFS stop_id to ATLAS sloid mapping coverage.

OSM Route Family Grouping Method
How OSM route relations are grouped into line families. Priority order: route_master → GTFS route ID → (route, ref, operator, network) → per-relation fallback.
| Grouping Method | Families | % of Families | Relations |
|---|---|---|---|
| route_master (explicit OSM grouping) | 2,636 | 92.6% | 7,860 |
| Normalized GTFS route ID | 5 | 0.2% | 7 |
| Synthetic key (route, ref, operator, network) | 207 | 7.3% | 254 |
| Per-relation fallback (no grouping key) | 0 | 0.0% | 0 |

Matching Paths
① Direct SLOID match
Matches where original_stop_id directly contains a valid ATLAS SLOID.
40,768
Assignments
② Strict matching
Matches on (UIC number, local ref) = (number, designation) in ATLAS.
19
Assignments
③ Coordinate proximity
For remaining: ATLAS stops with the same UIC number within 0.5m (must be unambiguous).
1,181
Assignments
④ Unique-number fallback
For remaining: if a UIC number maps to exactly one ATLAS row, use that sloid.
