To find out which bus to take, where it goes and when it should arrive right now in Aracaju, the most useful approach is to combine two channels. The SMTT bus lookup is the reference for searching a line and checking its route and timetable. The Cittamobi service for Aracaju brings together schedules, routes, stops and real-time arrival predictions when those data are available. In short: SMTT helps confirm the planned service; Cittamobi is more useful for deciding whether it is time to head to the stop.
SMTT or Cittamobi? The short answer
| What you need to know | Most useful channel | How to read the information |
|---|---|---|
| What route the line follows | SMTT | Use the official lookup to check the registered route for the line. |
| What the line’s scheduled times are | SMTT | Treat the timetable as the planned service, not as a guarantee of the exact arrival time at your stop. |
| How many minutes until the bus arrives | Cittamobi | Use the real-time prediction when it is shown for the selected stop and line. |
| Where the vehicle is and which stops come next | Cittamobi | The app may show location, stops, route and operational information depending on data availability. |
| Whether there is a detour, roadwork, event or temporary change | SMTT | Check recent news and notices, because an operational change may temporarily replace the normal route. |
How to check a schedule and route on the SMTT website
The official SMTT page has a section called Consulta de Linhas de Ônibus (Bus Line Lookup). It lets users search for a line and switch between Itinerário (Route) and Horários (Schedules). This is the best starting point when you already know the line number or name and want to verify what is officially registered.
- Open Itinerário e Horário de Ônibus — SMTT Aracaju.
- Search by line number or name.
- Confirm the correct direction. The same line number may appear in opposite directions.
- Open Itinerário to check where the line runs.
- Open Horários to check the planned operating times.
Before relying on a time, also check the type of day. Public transport lines may have different timetables for weekdays, Saturdays, Sundays or holidays. If your goal is to know whether the bus is arriving now, the official timetable is a baseline and should be supplemented with real-time information.
How to use Cittamobi to see when the bus is arriving
Cittamobi has a page dedicated to public transport in Aracaju and says users can check lines, schedules, routes, operational alerts and real-time arrival predictions. Mais Aracaju also directs passengers to the app to check bus routes and line times in real time.
- Open Cittamobi and make sure Aracaju is the selected city.
- Search by line number, line name or destination.
- Choose the correct direction.
- Select the stop where you intend to board.
- Check whether a prediction in minutes or vehicle location is available.
- Use the map and stop list to confirm that the bus serves the section you need.
If a real-time prediction is not available, do not treat a displayed scheduled time as a promise of exact arrival. The platform itself notes that predictions and operational data depend on availability in the local operation.
Scheduled time and real-time prediction are not the same thing
A scheduled time is the planned timetable for the line. It is useful for planning a trip, comparing service windows and understanding expected frequency. A real-time prediction is an estimate linked to the operation taking place at that moment. It can therefore respond better to traffic, spacing between vehicles and the bus’s current position, but it can also change or disappear when data are unavailable.
In practice, use this rule: plan with the timetable and leave home while checking the prediction. If you are still deciding which line reaches your destination, start with SMTT or Cittamobi’s route planner. If you already know the line and are about to board, prioritize the prediction for your stop in the app.
What to do when SMTT and Cittamobi seem to disagree
A difference does not necessarily mean that one channel is wrong. Often, each screen is answering a different question. Check the following:
- Confirm the direction: outbound and return trips may have different routes and times.
- Check the day: do not compare a weekday timetable with Saturday, Sunday or holiday service.
- Check the stop: a minutes-to-arrival prediction is linked to the selected stop; another stop will show another time.
- Look for an operational notice: an event, roadwork or closure may temporarily change the route.
- Separate timetable from prediction: a scheduled time and a live estimate do not have to match minute by minute.
SMTT continued to publish temporary route changes in 2026 because of races, events, construction work and terminal changes. On major-event or road-closure days, it is worth opening the SMTT website and checking recent news before assuming that the normal route is operating.
If there is a temporary route change
When SMTT announces a detour, the normal route may stop applying for a few hours or for the duration of construction work. In that situation, the latest operational notice should be considered together with what the app shows. Cittamobi may reflect part of the live operation, but official communication is the best place to understand why the route changed, which streets are affected and when normal service is expected to resume.
If the app shows a vehicle approaching but the bus does not appear at the usual stop during a closure, check whether the stop has been temporarily relocated. Platform changes at terminals can also happen even when the line number stays the same.
30-second checklist before you leave
- Confirm the line number and name.
- Check the correct direction.
- Review the official route if you are unsure where the bus goes.
- Confirm the day type used by the timetable.
- In Cittamobi, select the exact stop and check the real-time prediction when available.
- If there is an event, roadwork or closure, check recent SMTT notices.

For a quick check, the logic is simple: SMTT to confirm the line, route and timetable; Cittamobi to track the arrival now; SMTT again to check temporary changes. Using the three steps reduces the risk of choosing the wrong direction, waiting based on a timetable that does not reflect current operations, or following a route that has been temporarily diverted.
