Mr Lim Biow Chuan asked the Minister for Transport whether there are any plans to implement the green link determining (GLIDE) traffic system for all roads and to align standalone pedestrian crossings to the same GLIDE traffic system.
Reply by Minister for Transport Ong Ye Kung:
1. All traffic lights at junctions and standalone pedestrian crossings have been connected to the Green Link Determining (GLIDE) system.
2. GLIDE adjusts traffic signal timings dynamically to balance traffic demands between motorists and pedestrians. However, it is an old system with its limitations, as it measures traffic volume using detectors installed under the road surface at traffic junctions, which may not be sufficient. Our intention is to upgrade the technology and more details will be announced when ready.
