Provisional results, published evidence
When is this route reliable?
Every hour below is backed by this route’s settled arrivals. “On time” means no more than five minutes early or late, so a bus that leaves very early counts as a failure for the waiting rider.
Patterns by hour (0)
Not enough arrivals yet to split this route by hour.
No repeated pattern below 70% is yet established across at least three service days.
Scheduled bus, but not observed in realtime
0 / 6 scheduled trips published at least one position across 3 service days (0.0%).
This is not a confirmed no-show. A missing position can mean a cancelled or missed bus, but it can also mean an unassigned trip ID or an operator-feed gap. Otranspo publishes the gap because it matters to riders while keeping the conclusion honest.
Method: last prediction within ten minutes of each arrival; one arrival per trip, stop and service date. Trip coverage: GTFS schedule compared with any GTFS-RT position carrying the same trip and local service date. Sources and limitations.

What is being shown
The current public route group, its published schedule variants and stop patterns, current operations, and matching observed reliability where available.
How it was produced
1 current GTFS route record variants are grouped by operator and public route number. Stop patterns remain tied to their published variant; aggregated reliability records are not merged into an invented percentile.
Evidence dates
- Computed or assembled
- Sample
- No matching settled-arrival reliability sample is currently published for this public route.
- Coverage
- 2 published stop patterns containing 40 stop calls are available on this page.
- Method or data version
- last-prediction-within-ten-minutes-v1; f503960e30cc6164b028c6c9caa192dc500a6da15913bd3c57a3b654dc0649d9

Limits to keep in mind
- Schedule variants can apply on different dates. A grouped route is not a claim that every pattern operates today.
- Accessibility fields report only what the operator publishes; an unknown value is not confirmation of access.
