Open dated evidence

Evidence period: 2026年10月28日 – 2026年11月3日

Scheduled trips with cancellation notices

Trips in the published timetable marked cancelled without qualifying later matching vehicle observations in our archive. This does not prove the trip did not operate. Not counted: 6 trips with qualifying later matching vehicle observations. Trips with any notice: 11.

Trips needing investigation

4 of 468 trips with a usable feed window (0.9%) had no matching position.

These counts may overlap; do not add them. A missing position confirms neither cancellation nor a no-show.

464 with position · 4 to investigate · 0 excluded · 468 scheduled trips

Current feed. No explicit notice for this route in the current feed; this does not guarantee service. Observed: 2026年11月4日下午2:56.

Coverage, exclusions and sources

0 of 12 endpoint departures scheduled in the next four hours carried an explicit cancellation at the last check.

0 scheduled trips were excluded from the position check for feed or identity gaps.

Published position coverage: 464 / 468 (99.1%). This is not a delivered-service rate. 7 service days in this source.

Timetables retained before the service day: 7 / 7 requested days · 0 missing days.

Historical calculation: 2026年11月4日下午2:09

Method: explicit provider notices, archived trip windows and retained timetables. Predictions and positions alone do not prove that a bus ran or was missed.

What this route needs

Median provider predictions are 3 to 3.6 min later than the timetable in 6 hours of the day.

Predictions near the start are about 3.5 min later than the timetable, with a similar difference near the end. This does not establish the cause.

Next investigation: test terminal recovery and the preceding trip against operational records. Predictions alone do not establish the cause.

這是我們所知內容的簡短摘要。如果無法回答某個問題，我們會說明。

重點結論

營運機構的預測常與時刻表不同；實際到站時間沒有獨立量測。

71 in 100 eligible predictions were within 5 minutes of the timetable · 146,779 predictions checked

預測樣本數: 樣本較大

Based on 146,779 eligible provider predictions over 27 measured days, from 2026年10月6日 to 2026年11月3日.

Updated 2026年11月4日下午2:32

預測在哪些地點和時間多次出現差異？

這些是預測與班表之間反覆出現的差異，並非獨立測得的服務失誤。它們使用與上方結果相同的合格預測，但按站點而非時段分組，因此兩份清單不一定逐行相符。

17時–18時: 45 in 100 eligible predictions differed from the timetable by more than 5 minutes (4,784 predictions over 14 days).
18時–19時: 43 in 100 eligible predictions differed from the timetable by more than 5 minutes (4,796 predictions over 14 days).
16時–17時: 39 in 100 eligible predictions differed from the timetable by more than 5 minutes (4,570 predictions over 14 days).
15時–16時: 35 in 100 eligible predictions differed from the timetable by more than 5 minutes (4,517 predictions over 14 days).

已發布的時刻表：變更前與變更後

此頁面比較目前保留的官方時刻表與先前保留的版本。時刻表變更只說明原本的計劃,不能證明某個班次已經行駛。

從每份已發布時刻表中選出的服務日

我們會檢查新時刻表開始後的第一個星期一，以及一週前的星期一。所有數字都來自下列保留的官方 GTFS 版本。

所選日期中，至少有一個日期有新增或取消的特定日期服務。請將此視為假日或特別服務的情況，而不是平日一般的服務增加。

變更後，服務有改善嗎？

我們會比較變更前後各 14 天已確認的到站紀錄。只有在變更前後兩段時間都至少有 7 個服務日和 200 次到站紀錄時，我們才會公布比較結果。

校驗碼可讓任何人核對，是哪一份留存的時刻表產生這些數量。數量有變動，並不能說明原因、取消、營運單位的決定或對乘客的影響。

如何評估這條路線: 每站停靠的一般路線

我們把每個預定到達班次的最後一筆合資格業者預測，與官方時刻表比較。這些不是獨立量測的到達時間。結果至少需要 200 筆合資格預測。這裡採用乘客角度的目標：誤差在 5 分鐘內。

這些數據無法證明的事

公開資料來源沒有提供可靠的乘客人數，也沒有提供漏載乘客的事件。缺少車輛位置，本身並不能證明班次取消、未出車、中途折返或其原因。

這不是已確認的未發車。 找不到車輛位置，可能是班次取消或漏班，也可能是班次編號未指派，或是營運單位的資料來源出現缺口。Otranspo 公布這項缺口，因為這對乘客很重要，同時也會如實處理，不作過度推論。

Prediction check: the last eligible provider prediction no earlier than ten minutes before the scheduled arrival, counted once per trip, stop and scheduled Toronto calendar date. It is compared with the timetable, not an independently measured arrival. Trip-position 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. 來源與限制.
