SBS Transit - Travel info & alerts

About the app

The SBS Transit application, formerly referred to as iris, offers essential travel information aimed at improving the commuting experience for users of SBS Transit’s buses and trains.

In addition to providing real-time bus arrival times, the SBS Transit app delivers a variety of useful information, including specifics about bus routes, notifications regarding delayed or diverted bus services, and updates on any alterations to regular bus operating hours.

Furthermore, users can access information about the first and last train departure times, anticipated modifications to train service schedules, and notifications in cases of delays or disruptions in train services.

FAQs

Sometimes, two buses of the same service arrive at the same time with one bus being overcrowded and the other almost empty. Why?

The reason for this is largely due to adverse traffic conditions on the road and other conditions such as road closure, diversions, weather, accidents etc. Indeed, more than 70% of our delays or bunching are due to these reasons.

For example, assuming 3 buses started out being 10min apart which was sufficient to cater to the demand along the route (see below).

Bus 1 did not meet any problems and hence, was able to run on schedule. Bus 2 encountered a jam while Bus 3 did not encounter any problems. Hence, the time between Bus 1 and Bus 2 was lengthened, while the time between Bus 2 and Bus 3 was shortened (see below).

By taking more than its share of passengers Bus 2 slowed down as a result, while Bus 3 picked up fewer passengers which caused it to speed up. Bus 2 was thus caught in a vicious cycle that came to a head when the third bus caught up.

To the passenger on the ground, he would have waited 15min and it would seem that Bus 2 was crowded while Bus 3 was relatively empty. In the above situation, adding more buses is not a solution, as the same buses will end up being caught in the jam. More bunching will occur when they do eventually emerge from the traffic slowdown.

We assure our commuters that we try as far as possible to ensure that our buses arrive at regular intervals including adjusting the assignment of buses to suit real time conditions though there is a limit to how changes can be made.

It is easier for me to alight from the bus if I stand near the exit door, why should I move to the rear of the bus?

The capacity of a bus is a combination of its seating and standing capacity. When passengers fail to move to the rear and prefer to stand near the exit door, the flow of passengers becomes restricted within the bus. This will cause delay as the Bus Captain would have to appeal to passengers to move in to make space for others to board.

Not only is this tiring for the Bus Captain, it also causes delay to all passengers on the bus as well as those wanting to take the bus along the route. We urge our passengers to move to the rear to allow others to board the bus.

Likewise, we also urge our passengers to take the seat near the window if no one is occupying and not put their belongings on any empty seats.

Why does the Bus Captain drive so slowly?

We hope commuters can appreciate that traffic conditions on the road can vary. Our schedules, however, can only be planned to meet what is usually the expected traffic condition at the various times of the day. There will be times when the traffic conditions are unusually clear or congested and this often results in buses being too early or late.

When traffic conditions are especially clear, our Bus Captains are required to regulate speed if they notice that they are ahead of schedule. This ensures that the Bus Captains keep the arrival times at the bus stops as close to the planned schedule as possible to avoid any disruption like bus bunching.

From the perspective of the passengers on board the bus, the journey seems slow but to the passengers waiting at the bus stops along the route, they expect their bus to arrive on time as scheduled. Nonetheless, we will monitor our buses closely and make appropriate adjustments to the running time when necessary. 

Some of the air-conditioned buses are either too cold or too warm. Why can't the Bus Captain adjust the temperature?

The Bus Captains are not able to adjust the temperature. The temperature is automatically adjusted using climatic control. It is a fact that generally, you will feel colder in the morning and not as cold in the afternoon in the air-conditioned bus due to the external ambient temperature although the settings of the air-condition remained unchanged.

We have rigorous maintenance program for bus air-conditioning. If the air-conditioning in the bus is found to be faulty, it will be sent for repair immediately. We welcome our passengers to call our feed back hotline, 1800-287 2727 should they find the air-conditioning in our buses to be malfunctioning.
