The Green Link Determining (GLIDE) System controls all traffic signals in Singapore. As traffic flow changes, it responds by adjusting the green time accordingly.
GLIDE also links adjacent traffic signals to allow vehicles to travel from one junction to another with minimal stops.
What are the benefits of GLIDE?
GLIDE provides these benefits for road users:
- Allocates green time for motorists and pedestrians based on demand
- Provides "green wave" link between adjacent junctions to minimise the number of stops by vehicles
- Allows traffic signal faults to be rectified quickly
How does GLIDE work?
The GLIDE system detects the presence of vehicles and pedestrians at the junctions of major roads. It allocates green time based on the traffic volume in each direction.
