SINGAPORE - Commuters now have more accurate bus arrival timings on their mobile apps and on information panels at bus stops.

The Land Transport Authority (LTA) said on Thursday that with a fine-tuning of its bus arrival information system, 95 per cent of estimated timings now fall within three minutes of the actual arrival time.

This is an improvement from about 80 per cent in April 2015, when the LTA launched its system. Before that, public transport operators SBS Transit and SMRT operated their own bus arrival information systems.

The LTA's system uses location data transmitted by all 4,700 buses on the roads via GPS devices.

The data collected is transmitted every 20 seconds to the LTA's system, which then predicts the bus arrival timings based on real-time bus location data, bus route information, bus timetables and historical travel times.

LTA said that over the past two months, it has received commuter feedback about inaccurate bus timings on certain routes. It has since improved on the software prediction algorithms and the transmitter software.

The LTA said it receives over 10 million download requests for bus arrival timings every day.

Commuters can get bus arrival information either through LTA's own MyTransport.SG app or through third-party applications such as SG NextBus, SG Buses, bus@sg .
