Written Reply to Parliamentary Question

Mr Fadli Fawzi asked the Acting Minister for Transport as of January 2026

a.           what are the top 10 traffic junctions with the highest volume of peak hour traffic and congestion in Singapore; and

b.           whether any steps will be taken to relieve congestion at these traffic junctions, such as reviewing traffic light timings.

Reply by Acting Minister for Transport Jeffrey Siow:

1.           Major junctions near expressways or major arterial roads leading to and from key commercial and industrial zones typically have the highest peak hour traffic volume.

2.           Our adaptive traffic light system, Green Link Determining System (GLIDE), adjusts traffic light signals based on prevailing traffic conditions to improve traffic flow. The Land Transport Authority (LTA) will continue to leverage on technology, such as predictive artificial intelligence, to enhance traffic management.
