Markers move between GPS fixes using measured progress along the published route. They pause after one measured reporting interval, on a measured standstill, or when evidence becomes stale.

Repeated problem stops: CARLETON A, TRANSITWAY / TERMINAL, SOUTHVALE / RUSSELL, SOUTHVALE / AD. 2450, SOUTHVALE / ERINBROOK and 1 more. These are highlighted from route-specific settled arrivals with at least 60 observations over 3 days; the pattern does not prove a cause.

Would you count on route 48?

No sign-in needed. A vote from a device that is not signed in counts a little less than one from an account, and a person who rates many routes counts a little less on each, so no one voice outweighs the rest.

Verdict

What this route needs

Timetable short by 3.1 min in 1 hours of the day.

08:00 drops to 64% on time, against 86% the rest of the day.

Scenario: 3 min more running time on 86 trips. The schedule-block model adds no buses; fleet and workforce feasibility are unverified.

Assumptions: published departure times, trip blocks and service pattern stay fixed while running time changes. A scheduler must test headways, transfers, recovery, fleet circulation, operator shifts, labour rules and cost before use.

Route check

How route 48 is doing

A plain-language summary of the strongest evidence we have. We say when the data cannot answer a question.

Bottom line

Usually close to schedule, but check the problem times below.

81 in 100 arrivals were within 5 minutes of schedule · 69,280 arrivals checked

Confidence in this summary: High

Based on 69,280 arrivals over 20 weekdays, from Aug 20, 2026 to Sep 19, 2026.

Updated Sep 19, 2026, 1:32 p.m.

Where and when does it keep going wrong?

These are repeated patterns, not one bad day or an unverified rider report. They are measured the same way as the verdict above, over the same arrivals, but they are counted per stop rather than per hour, so the two lists need not match line for line.

  1. 8 a.m.–9 a.m.: 36 in 100 arrivals were more than 5 minutes early or late (3,559 arrivals over 11 days).
  2. 4 p.m.–5 p.m.: 31 in 100 arrivals were more than 5 minutes early or late (3,912 arrivals over 12 days).
  3. 2 p.m.–3 p.m.: 31 in 100 arrivals were more than 5 minutes early or late (2,356 arrivals over 12 days).

Schedule change check

Published schedule: before and after

This compares the current retained official schedule with the prior retained version. Schedule changes are facts about what was planned; they do not prove that a trip ran.

Current published schedule began September 18, 2026

Selected service day from each published schedule

We check the first Monday after the new schedule began and the Monday one week earlier. Every figure comes from the retained official GTFS versions named below.

At least one selected date uses added or removed calendar-date service. Treat this as holiday or special-service context, not ordinary weekday growth.

Did service improve after the change?

We will compare settled arrivals for the 14 days before and after the change. We publish the comparison only after both sides have at least 7 service days and 200 arrivals.

Still collecting: before has 46,693 arrivals over 14 days; after has 4,762 arrivals over 1 days. No improvement or decline is claimed yet.

Checksums let anyone verify which retained timetable produced the counts. A changed count does not identify a cause, cancellation, operator decision, or passenger impact.

How this route is judged: Regular all-stop route

We compare observed arrivals with the official schedule. A result needs at least 200 arrivals. Within 5 minutes is the rider-facing target used here.

What this data cannot prove

The public feed does not provide dependable passenger counts or passed-up-rider events. A missing position does not by itself prove a cancellation, no-show, short turn or cause.

See the definitions, thresholds and evidence order
  1. Official current feed: explicit cancellations, skipped stops and active notices.
  2. Matched observations: vehicle positions and settled predictions tied to the official schedule.
  3. Official timetable: what was planned, kept separate from what was observed.
  4. Rider and operator reports: leads about routes, times and places to investigate, not numeric proof by themselves.

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.

Scheduled bus, but not observed in realtime

506 / 616 scheduled trips published at least one position across 1 service days (82.1%).

  • 10:006 / 28 trips without a position78.6%
  • 19:006 / 28 trips without a position78.6%
  • 16:0010 / 48 trips without a position79.2%

  • 04:002 / 10 trips without a position80.0%
  • 07:009 / 45 trips without a position80.0%

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.

Arrival check: the last prediction within ten minutes of arrival, counted once per trip, stop and service date. Trip check: the timetable kept before each service day, matched to recorded positions. Exact IDs are preferred; an OC timetable suffix is matched only to one trip on the same route and date with an overlapping time window. Missing timetables, ambiguous matches and feed gaps stay labelled; they are not confirmed no-shows. Sources and limitations.

  • 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.
