SINGAPORE – Get ready to wave your hands at traffic lights instead of pushing buttons! From the fourth quarter of 2025, the Land Transport Authority (LTA) will be replacing all mechanical pedestrian push buttons with touchless microwave sensors. That’s right—no more germ-riddled buttons for us!
Touchless Technology in Action
Pedestrians will simply wave their hands in front of these new sensors to activate the traffic lights. With around 11,500 push buttons at approximately 2,790 traffic junctions across the island, this upgrade is set to take about six years to complete.
Improved Hygiene and Accessibility
- Less touch, more cleanliness: This change stems from concerns over hygiene, especially in light of the Covid-19 pandemic.
- Inclusive design: The new sensors will cater to visually impaired individuals with Braille that says “Touch to activate,” along with an auditory signal when activated.
How It Works
The trials began in 2022, where two types of sensors—infrared and microwave—were tested. While both met the LTA’s performance standards, microwave sensors were selected for their superior adaptability in varying weather conditions. This technology will likely result in reduced maintenance costs as well.
A Debate on Accessibility
However, not everyone is convinced. Some, like 28-year-old Shalom Lim, who suffers from Duchenne muscular dystrophy, expressed concerns that waving a hand might not be practical for everyone. Lim suggests that further innovations, like using near-field communication, could enhance accessibility for those with limited mobility.
Global Trends Followed
Other countries, including Australia, the USA, and Canada, have already begun implementing similar touchless systems, highlighting a trend towards improved hygiene and accessibility. The LTA’s new sensors not only make things easier for pedestrians but can also reduce maintenance issues linked to mechanical buttons that tend to wear out with continuous use.
The Road Ahead
With tender processes already underway, the winning contractor is expected to design the new sensor systems that will soon become a familiar sight at Singapore’s junctions. Completion of this ambitious upgrade project could make Singapore a leader in pedestrian safety and hygiene.
