SBS to explore SG's first intelligent bus braking system
14 May 2025|20 views
Even when aiming to avoid a collision or an accident, the application of a bus' emergency brakes can still cause some pretty serious injuries. For instance, a recent incident saw a woman thrown forward, breaking the glass panel in front of her and requiring five stitches on her arm.
Ostensibly to prevent such further incidents, SBS Transit has signed a Memorandum of Understanding (MoU) with Streamax and TNT Surveillance to develop a Responsive and Adaptive Braking System (RABS), set to become Singapore's first, for buses.
In conventional emergency braking systems, applying the brake often causes it to lock, leading to sharp, sudden jolts. RABS, in contrast, is designed to deliver more controlled and gradual deceleration. This approach not only helps prevent collisions but also significantly reduces the likelihood of passengers being thrown off balance or injured.
RABS will also use radar sensors and cameras to continuously monitor the vehicle's surroundings, detecting hazards and responding within 40 milliseconds - more than 35 times faster than the average human reaction time - to help avert accidents with minimal disruption to passengers.
More importantly, RABS will be designed to handle the dynamic nature of traffic by constantly adjusting its braking parameters based on the traffic conditions and speed of the bus. However, in situations where a collision is unavoidable, RABS will automatically respond by moderating the braking force to lessen the impact and help reduce the risk of injury and minimise damage to the vehicle.
Beyond its immediate safety benefits, RABS will also transmit real-time data directly to the Bus Operations Control Centre, enabling quicker response times and providing SBS Transit's operations team with improved situational awareness during critical moments.
Scheduled for a pilot launch in the first half of 2026, RABS will further strengthen SBS Transit's comprehensive suite of advanced safety technologies by working in tandem with existing systems like Golden Eye, Mobileye, and the 360 Surround View System.
