SBS Transit, the biggest public bus operator in Singapore, and Stratio, the leading provider of predictive maintenance for public transport, today announced a strategic collaboration that will boost service reliability of SBS Transit’s buses through a fleet-wide implementation of predictive maintenance technology. This marks the first-ever deployment of predictive maintenance of this scale representing 62% of Singapore’s public bus fleet.

Powered by Artificial Intelligence (AI) and Machine Learning (ML) algorithms, SBS Transit started installing this system on 1,000 of its buses and, has experienced at least a 20% drop in bus breakdowns.

In April 2022, SBS Transit started installing this system on 1,000 of its buses and experienced at least a 20% drop in bus breakdowns.  With positive feedback, it has begun to install it fleet-wide where work is expected to complete by end-2024. With the deployment of this technology across more than 3,000 SBS Transit’s buses, its maintenance teams will gain real-time visibility over critical systems and components such as brakes, electric systems, and fluid levels, and will be able to remotely monitor data from over 200 vehicle parameters. This will effectively minimise downtime, save costs, and enhance passengers’ experience.

With this new phase of roll-out, the system will also be equipped with the ability to predict faults with the bus air-conditioning system where failures related to it rank among the top three leading causes of bus repairs. Being able to spot early signs of trouble to intervene would improve the commuters’ experience. With this added feature, which was jointly developed successfully between both partners in the initial phase, SBS Transit’s technicians will receive detailed fault reports whenever a deviation in the bus internal temperature is detected to enable them to carry out corrective works to maintain passenger comfort.

The Stratio bus condition monitoring system will also be piloted on the electric buses that SBS Transit operates. This will mark a first for electric buses to be installed with a bus condition monitoring system locally. Significantly, it will monitor the state of health of the bus’ battery pack for operational efficiency and effectiveness. As part of the collaboration, both partners will also work on refining condition monitoring features that are better suited to Singapore’s weather and road conditions that could extend their lifecycle, support operations, and ensure a successful transition to zero emission buses. This will involve collecting relevant data as part of the process and this project is expected to complete by end-2025.

Mr Jeffrey Sim, Group Chief Executive Officer of SBS Transit, said: 

“We are committed to bus service reliability as part of our efforts to promote public transport usage. It is also aligned with our sustainable mobility roadmap. With this bus condition monitoring system, we are able to anticipate faults and undertake predictive maintenance and contribute to better service reliability and elevate our passengers’ travel experience.

As a leading public transport operator, we have also taken a step forward by extending this predictive maintenance technology to our fleet of electric buses where 50% of Singapore’s public fleet will be green by 2030. Our investment in this system will enable us to do a better job at operating and maintaining these zero-emission vehicles and we will continue to set the standards for the industry.”

“SBS Transit is at the forefront of a global revolution in transport technology. We are thrilled to extend our partnership to expand cost savings and efficiency gains to their entire Singapore operation,” said Rui Sales, President and co-founder of Stratio. “This collaboration reinforces Singapore’s reputation for having one of the finest transportation systems globally,” he added.
