Why is Singapore replacing pedestrian push buttons?

Question

Accepted Answer

Singapore is replacing pedestrian push buttons with touchless microwave sensors to improve hygiene and accessibility.

Singapore's Land Transport Authority (LTA) will begin replacing its 11,500 mechanical pedestrian push buttons with touchless microwave sensors from the fourth quarter of 2025. This initiative is driven by a desire to reduce physical touch points and enhance public hygiene, a move that was informed by trials conducted in 2022 and 2023. The new system will also incorporate features to assist visually impaired pedestrians, ensuring a more inclusive crossing experience.
Enhanced Hygiene and Reduced Touch Points

The primary motivation behind the transition to touchless microwave sensors is to minimise contact with public surfaces, thereby improving overall hygiene. This decision follows successful trials that demonstrated the effectiveness of such technology in reducing the need for physical interaction with pedestrian signals.
Superior Technology for Reliability

Microwave sensors were selected over other technologies, such as infrared, due to their demonstrated accuracy and reliability across a range of weather conditions. This choice ensures that the system will function dependably, regardless of environmental factors, providing a consistent user experience.
Accessibility Features for Visually Impaired

The new sensors will include specific accommodations for visually impaired pedestrians, such as Braille instructions and auditory signals. These features were developed in consultation with the Singapore Association of the Visually Handicapped, ensuring that the updated crossings are accessible to all members of the community.
Phased Implementation Over Six Years

The complete rollout of the new motion sensor crossings is a significant undertaking, with the installation process expected to span a period of six years. This phased approach will allow for systematic replacement across the island, ensuring a smooth transition to the new touchless system.
