Verdict
What would fix transit here
Worked out from the routes that serve this ward. Each item names the route, when it happens, and what would change it.
39 of 49 show repeated provider predictions later than the timetable, consistent with a possible scheduled running-time shortfall. A scheduler should test that scenario against operations; labour, fleet, recovery and transfer impacts are not established here.
Worst here: route 12, predictions later than timetable 09:00 to 21:00, 4 min late.
Best here: route 67, predictions consistently close to timetable, 90%.

O-Train evidence
What we know about train service here
Trains are not in the public data feed
The bus punctuality reports compare archived arrival predictions with published schedules. They do not count independently measured physical arrivals. Otranspo has no comparable public train-position dataset for these reports, so those bus figures cannot show where a train is or whether Lines 1, 2 and 4 run on time.
Publishing train positions, their timestamps, and the measurement method would help build a separate, verifiable record of rail service. The missing dataset does not establish how the trains performed.
Recent shared train observations
These are rider sightings approved by a moderator. They show a reported time and place. They are not official train positions, a complete train count, or proof of a cause.
No approved rider observation matches this place or line in the last 31 days. That does not mean no train ran or no problem occurred.
How SOMERSET is doing
These indicators separate repeated delay from variation in the operator’s arrival predictions. They suggest questions for planners and operations staff; they do not establish the cause or prove when buses arrived. Each figure shows its route-hour sample.
Measured over 724 route-hours. 11 more were observed too thinly to count, and are excluded rather than assumed good.
Scheduling
Repeated late predictions can point to a timetable worth reviewing. Check actual arrival and dispatch records before deciding whether running time needs to change.
- Who can fix it
- A service planner
- What it costs
- Cost unavailable until fleet, labour, recovery and transfer effects are tested.
Predictions close to the timetable
77.5%
Route-hours where the median eligible arrival prediction is less than one minute early and less than three minutes late.
Route-hours with repeated late predictions
162of 724
Route-hours where the median eligible arrival prediction is at least three minutes late. Review running time against actual operating records.
Route-hours with early predictions
1of 724
Route-hours where the median eligible arrival prediction is at least one minute early. This does not establish that buses departed early.
Typical predicted delay
3.9min
The typical median predicted delay in flagged route-hours; not a validated amount to add to the timetable.
Operations
Wide variation in arrival predictions calls for an operational review. Traffic, dispatch, boarding and timetable design may contribute; these predictions alone cannot identify the cause or the remedy.
- Who can fix it
- Operations, and often the road itself
- What it costs
- Cost unavailable until the operational cause and remedy are established.
Prediction gap below twenty minutes
98.5%
Route-hours where the 95th-percentile eligible prediction is less than twenty minutes later than the median.
Route-hours with wide prediction gaps
11of 724
Route-hours where the 95th-percentile eligible prediction is at least twenty minutes later than the median. The cause needs investigation.
Typical prediction gap
21.8min
The typical gap between the 95th-percentile eligible prediction and the median in flagged route-hours.

Provider prediction agreement
69.2% of eligible provider predictions were within five minutes of the timetable. 245,864 of 355,464 settled trip-stop predictions at stops inside this ward matched that range across 20 weekdays with feed evidence, from Oct 3, 2026 to Nov 3, 2026. These are provider predictions, not independently observed arrivals.

Vehicle visibility to investigate
The current summary uses seven days. For every route, you can also open yesterday, the last 7 days, or the last 30 days and inspect the day, scheduled trip, excluded feed gaps, and every observed public vehicle ID. An absence does not prove a vehicle fault or operator decision.

A ward boundary, route inventory, destination list, population count or employment count supplies civic context. None of those values alone measures passenger demand, household trip effects, transfers or daily attendance.
Ottawa wards are municipal wards. They are not Gatineau electoral districts, and results from the two boundary systems are not interchangeable.
Evidence behind this pageOpen the definition, method, sources, dates, coverage, and known limits.
What is being shown
A ward-level inventory of scheduled transit, public washrooms, drinking-water locations, and eligible final OC Transpo provider predictions at stops inside the ward.
How it was produced
Current imported records are assigned by point-in-polygon to the sourced ward boundary. Reliability uses one eligible final provider prediction per trip, stop, and service date in the latest 28 completed service days. Within five minutes is measured against the timetable, not a physical arrival. Publication requires 20 weekdays with prediction evidence and 500 eligible predictions.

Limits to keep in mind
- Counts describe the published inventory inside the boundary, not service quality or access from every address.
- Reliability covers final OC Transpo provider predictions at geographically assigned stops; physical arrivals are not independently measured. Rail and trips without eligible prediction evidence are not represented.
- An unavailable count remains unavailable. It is not changed to zero.
How we measure this
For each trip, stop and service date at stops inside the ward, we keep the last eligible OC Transpo prediction and compare it with the timetable. It counts as within five minutes when the two are no more than five minutes apart. This is not a physical arrival.
The window is the latest 28 completed service days. A result is published only with 20 weekdays of prediction evidence and 500 eligible predictions. Route results cover each whole route, not only the part inside the ward.
